Just a note on the TCM - my brother-in-law has an '07 Duramax that started having the intermittent shift issues. It looked, smelled, and quacked like a failing TCM, so he replaced the TCM. It fixed it for all of one day, then the problem came back. A few days later his son noticed that something looked queer with one of the speed sensors on the transmission. Replacing that speed sensor fixed the shifting problem. Don't forget that with most electronic control systems, you need to check both the sensors and the actuators, as well as the controller and the wiring between everything.

I cannot stress enough this video is as good as it gets! This is real information from those who live DURAMAX. Thank you immensely. ...liked and subscribed.
Really impressed with Ryan and his shop. More I hear/see the more depressed I get because I don't have a specialty diesel shop like his near me in OH ...
I'm not a mechanic but speaking from experience on my Duramax and had this issue time and time again. FIRST place I would check is this..check the fuel filter/head assembly. For some reason mine seems to collect contaminants and foul up the filter/head assembly. Remove the fuel filter. If that is the issue you will certainly see all the buildup on it and know it needs cleaning.
I have got to add a commentary if Ryan isn’t a chip off the block I don’t know what. You can tell this young man has spent some time in his dad’s shadow and has definitely learned a thing or three. It’s great to see a young man who has some of his old mans style. Me and my brothers used to break balls by saying “Oh, you’re just like dad!” We smile at each other now and say thank you because we had a great dad. I know they drive us crazy when we’re teenagers I mean who’s dad didn’t come off with a “don’t make me put a foot in your ass or I’m looking for a place to park my foot and your ass is looking pretty good!” but they are doing everything because they love us. So I tip my hat to your father.
More duramax talk! L5P please! I daily mine and I don't tow a lot. I am going to add an edge insight to one of my next mods so I can manually regen it. Then banks rear diff cover. Thanks!!!!!
Yes it was the idler and belt tension pulley that got me stranded. Tension-er seized up at 70 MPH and you were right Scary. No brakes,or power steering.
A couple things on the LLY tractor comment. I cant remember the millisecond necessary to trip your engine into the mode where it cancels out 4 cylinders but it is minute. I dont agree with not bracing the wiring harness, on your FICM, by cutting the wire ties. Those wires are small as all get out and need the stability. What I did is cut a rubber hose to the length needed and split it up one side. Put it around the harness and resecure the harness back to the bracket. It wont rub through and reinforces the harness as a whole. Also on the left front side of the engine, on #2 cylinder, there is a wire that runs down the front of your engine that is connected to your injector wiring harness. That wire is not secure and stresses your #2 injector plug. Stabilize that wire with a wire tie so it doesnt allow it to rattle the harness when going over bumps. If #2 detects that lost contact it will cancel out #2, 8, 3, and 5. If #7 detects lost contact it will cancel #1, 7, 4, and 6. Either will give you the tractor effect. On #2 and #7 I took a plastic tooth pic, the flat part, wedged them into the connectors on the back side in the plug, cut them off flush, and tightened the fit of the contact. Have not had that problem again for over 200k now and I didnt have to cut the harness to fix it.
I bought one of these a few months ago. My TCM failed today idling in a parking lot. Was able to get home going about 40mph. No highway so that was good. I'll change it out tomorrow. No down time!! Thanks guys!
Swapped my TCM to the Ryan's Diesel Service pre-programmed unit and back on the road. Great product guys! Buy yours now before supply chain issues get worse.
I work at an indy shop, we don't see too many newer duramaxs but when we do it's nearly always dpf related.. we have a few farmers that let them idle a lot and are not on the highway much like you guys were taking about, these trucks don't like it. I've done a few def tank heaters, couple def injectors, and some egt/nox sensors as well. One of our customers has a 2015 and it's in the shop about every 6 to 9 months because it just won't regen.
Glow plugs . I had one bad one . I decided to change all of them at one time . I found three different makes . Lbz 2007 classic I got it at 100k . I love my truck .
From watching this video, looks like im going to do a little bit of insurance shopping with this Ryan's shop just to have in the glove or tool box. Such as getting a spare TCM, and replacing the idler pulleys etc. Great video. Seems like the LBZ dodged a lot of the problems mentioned here, although we are not immortal 100%. But its encouraging no less.
Many of the reasons i went with the 6.0 gasser when i bought my new 2500HD back in '16. It's no powerhouse, but it gets the job done consistently, without all the headaches.
@@jredd801 This was my first 6.0. I've literally had zero problems with it in this first 5 years. I still have an old '93 Chevy 2500 with the 6.5 turbo diesel. But it's a manual trans, mechanical injection pump, zero emissions regulations..the way they should be! 375,000 + miles
I have a 02 with 298,000 on it an 3/4 of them miles are towing a 32' gooseneck, injectors, front end rebuild, rear axle seals an now a new key switch ignition, an another set of infectors, only things done, more fuel, air, tuned has been a good truck.i bought with 20,000 on it. Always carry a spare belt an one or two idler pulley in the tool box
All great stuff 🤘🏼 LMM owner here, and love my Edge Insight CTS II monitor. About to start a project with some hardware from ProFab, HSP, and a couple other things. Can't wait!
I have had my LLY since May 2013 with 178k miles.....the only major problem was a fuel regulator switch 2 weeks after I bought it. The dealer charged me over a $1000 for the repair. That's the only major problem I've had.....now have 296k miles with just basic maintenance. I love my LLY!!!
@@danielellis2271 I had the same deal , pressure regulator replaced it myself also did the water pump and my egr cooler was plugged up nothing easy to fix but not to bad if you have some ability.
I got an alarm on DEF. My shop replaced a sensor upstream of the regen box because it was wasting diesel. It would not reset the panel. Turns out the outlet sensor was slow to react and had to be replaced to allow the panel to reset. Took my shop almost 2 weeks to hunt this issue down.
Test drove a 2009 GMC Duramax the other day with only 70,000 miles on it and previous owner only used for towing 5th wheel. First time I got on it check engine light came on and transmission was stuck in seemed like 3rdish gear. Dealer called next day and said low battery caused the issue. Ever heard of this?
I would love an lly hour. Trying to learn how to make my late husband's 05 c4500 last forever. He loved that truck, only has 50k on it. Found your channel about 3 weeks ago and love it. My dream is for you and Ryan to work your magic. Keep up the awesome work!
My son and I each have ‘03 LB7s in mid-200K’s. I did fuel injectors and lift pumps on both (tough work, but I’m not a mechanic and I got it done) and they’re both strong trucks. Yes, old diesels need maintenance, but few gas trucks will last this long at all, and the LB7s get great fuel economy compared to gas. If you don’t want to but a new truck every 10-15 years, diesel is king.
Oh yeah! Had mine go out 50 Miles from home. TCM is a must when your Duramax is completely different and not shifting and All 🏁 Great information video thanks Brothers 👍
Great info!! I know there are many videos out there, but knowledge is power. It would be great to have engine specific fixes (LMM, LBZ, etc) Keep up the good work!
Thanks guys for sharing all your knowledge , I do know my way around Non diesel cars , but I don't know much about diesel. I have adquired a 2006 duramax that I plan on fixing up as a father and Son Project . Thanks again keep up the good work. And you guys got all my support. God bless.
Thanks for the video! Hey, do a video of the same and talk about the LB7, LML, LLY, etc.etc, and discuss the vulnerabilities and the advantage of each! And, include the L5P, that's my new baby!!
Own a 04 LB7 since new ,use Howes fuel conditioner since new 276k on the truck , still running factory injectors , no smoke , no fuel in crank case , always use the best fuel filters every 10k . Great truck
I own 2 Duramaxes, 1 is a 04 with over 260,000 miles zero engine/gear issues, the other is a 15 with 120,000 miles, installed lift pump, converted CP4 to CP3, had exhaust issues twice, problem fixed now, no more issues.
Great video guys. Keep em coming ! I carry a new spare serpentine belt in a sealed plastic baggy. One time I started the truck and heard a big whummp and my belt broke. Turned out a squirrel was in there. May he rest in peace, or two pieces I mean.
Great video guys! I would definitely like an LMM specific video on Fuel Pressure issues and Limp Mode. I have almost a million Kilometers on my 2007.5 stock and only started having problems recently. Got rid of the old exhaust and put just pipe and muffler on. Runs much better now but still goes into Limp Mode a lot due to Low Fuel Rail Pressure.
Put a lift pump on it like FASS or AirDog. It’s leaking air into the head unit of the factory fuel filter primer pump. The gaskets get old and leak air and drop fuel rail pressure and put it into limp mode. Replace those gaskets also.
@chip7522 if I'm not mistaken also check your fuel lines. They like to kink especially with that much use and time on em. But lift pump like you said will just make his life better.
Hi Zachary, I did replace fuel lines several months ago and made no difference. I am also in the process of replacing small lines on top of engine compartment now. We'll see what that does I guess.
I have a 2002 GMC Sierra 3500 with 310,000 miles and I love it it’s been a great truck very reliable it has plenty of power almost daily I pull a trailer with it
Bought my first Duramax a few years ago now and have to say, the most vital thing a new owner can do is watch your channel religiously, that’s no BS. You guys nailed it on this video, I’ve had, and more importantly solved every single issue you’ve covered. Would have dumped enough money to buy another truck had it not been for your videos showing me how to deal with all of it myself.
Have a lly dually, pressure release valve was releasing at 13000psi causing limp mode. Truck is stock. Replaced fuel pressure regulator and replaced fpr valve with stock piece. Still got limp mode. Now replaced fpr valve with blank plug. No more limp mode. Discovered that injector pump has built in release for over pressure so a second fpr valve not needed. This only works for stock built engines not modified engines. Truck now runs like new.
I've got a low mileage 67k 2015 LML Duramax. Have went into reduced power mode twice towing heavy with no warning. First time was a bad DEF temp sensor at 45k and second time was 9th injector failure at 65k. I was able to clear the code a couple times each and drive to my destination. However both times were freeways speeds on grades with traffic. The pucker factor is huge when you hear a ding, get a reduce power message and go from 70 mph to 20 mph right now.
I have a 2013 one ton dually I live in east Lansing Mi it has 97000 miles about 23000 miles we pulled a Airstream trailer it weighs 6600 pounds. I’m very impressed with you guys maybe once good weather comes around I will make a appointment and have do some PM thank you 😊
I love the Duramax talk especially about the older models in 2005 she been talking about the 2006 is and 2010s I'm looking at buying me one so I need to know as much information that I can possibly get cuz I own it a Ford and they kept on breaking down the 6.0 the 6.2 the 6.4 stayed in the shop so I'm looking at a GMC instead of buying a new model 2020 I rather work with a older model and do majority work myself instead of being in the shop all the time and upgrade that engine like I want to so I appreciate everything you talking about continue to do what you do doing a wonderful and amazing job
Love this type of video, I have a 02 lb7 with 192000 on it . It still runs good but I'm getting nervous. I've owned it 8 years and never had one issue so I know something is coming. Its completely stalk other than a 2 in suspension lift.
I like your comment about buy a gas engine. I think the consumer grade diesel engines are such a rip off. They are too complicated for the basic mechanic, parts are way to expensive. These trucks are not reliable. You are almost better off buying a class 6 or class 8 truck. It will get the same mileage. The fact that the industry is forced to try to clean up the exhaust can add $10,000 to $15,000 operating cost over the life of the vehicle. I am a fleet manager. I have lots of Power Strokes, Duramax..... Sorry, that's just my opinion.
I’m expecting delivery of a new Chevrolet 3500 High Country L5P powered dually next month that I ordered in March and a dual remote oil bypass system from Amsoil first thing and then figure out what the best route of tuning/deleting to go but look forward to the journey and getting all the knowledge I can gain in the process!!!! Thanks for the videos I have gained a bunch of information right here already!!!!
LML Duramax, deleted and tuned thought had ECM/PCM issue, no comms with OBD scanner at times/ stabilitrak, traction control on dash and no crank. Was almost certain ECM was bricked and was going to replace when I took off driver side wheel well and just moved the engine wiring harness around and then the truck would start. It was intermittent and an electrical automotive shop already replaced the fuse box on the driver side a year before for the same sporadic behavior while driving. I used to think it was a fuel rail pressure or fuel prime issue but it was electrical all along. The company that made the tuner is out of business, my concern was replacing the ECM and having to have a different tune installed that's supported because of the EGR delete... Thankfully its not the case, hope no one else has that issue with the engine harness
Hello again Guys! Thank you for the reply. I should have mentioned that I already added a Lift pump and it still does the same thing. I also eliminated the filter pump and new seals. Again, same issue. Bob
Thank you for the information on all duramaxs. 04.5 lly owner(inherited,and happy!) I've learned so much from you. Really want to work on trucks,especially duramax. Subscribed to both channels to keep up.
I always love diesel talk I hope you guys make a nother video on the Duramax I like to have the knowledge of what to expect if something happens with my truck
2012 Lml...low miles 85k, I've had most of those issues, nox, pipe, def heater, and TCM. Also a big thanks to Ryan's for the TCM shipped to Texas. What was the Bosch CP4 plug for insurance?
Awesome content!! I always like this kind of information, so that I can be prepared. Thank you both for sharing the knowledge. Please do more videos on these topics. My LLY and myself will be happy.
Good video.. How bout you do a vid like this with the truck that started it all...2001 LB7 with all its quirks and phantom limps..limps with codes..2001 factory programming issues..etc..etc..
I have a 2013 LML. It has a mini max and deleted with 4 inch exhaust. When I first bought it it would run like a scalded dog in performance mode (like spin the tires at 60mph when punched kind of fast) I have since added an air dog 65gph lift pump, egt and tranny temp gauge and exergy fuel system saver and have now noticed it doesn’t “seem” or sound as fast, it still runs fine as a daily driver though and for towing but won’t spin the tires at all (I did put new tires on though so that may be part of it) . It Also it used to make a loud hiss as it cycled the turbo during start up that now doesn’t do it as loud at all. I am leaning towards either time for a new air filter (or has the AFE power air filter) or maybe some metal shavings got into the turbo when I drilled the exhaust for the egt probe...or it’s the fuel saver (I’ve heard others say they removed them because it robbed power). Anyway, what are your thoughts on this? Thank you in advance.
Transfer case pump rub up through the 07 Classic. Leaking power steering and transmission lines. Glow plugs LBZ. Seals in the fuel filter heads after a period of years.
I have a 2005 Duramax LLY, I remember because it reminds me of “Lilly”… I have 206,000 miles pulling a 10k lb 5th wheel trailer and now I’m having issues overheating while climbing hills in hot weather. I had to pull over every 35 miles as my engine overheated and low cool warnings came on. I drove 150 miles adding about 10-12 gallons of coolant sometimes after only 5 miles. I made it home but realized I blew a head gasket which I’m not looking forward to paying for the repairs. Just FYI. Time for a new truck I think.
Here is another tip on Duramax cooling systems. You are dealing with a lot of aluminum in the system. Its highly susceptible to corrosion. You want your coolant to have a neutral PH. Most tap water water is acidic. Distilled is the best. First off get rid of that red coolant!! That garbage clogs things up. Second, after switching to green, put in 2 bottles of Napa Cool 4056. It will stabilize your coolant PH. I have taken out water pumps and not had to change the housing because there was no corrosion on systems that were neutral. You can check your PH with a guage or litmus paper that you can pick up at any plant store.
Gonna be on the road so will take off with all sorts of preventive items. ...some of the stuff in your description that was used on the truck Mods. ...and tools, spare parts, rescue stuff, name it. TCM definitely. Was going to get the GM TECH 2, but now I have seen this video, I am holding off. I am new at this shtuff, thankful to get any information to consolidate my understanding. ...aware of the CP4 Achilles' heel! ...and the fuel pre-filter issues, and how bad fuel can destroy a DURAMAX! My 2011 6.6 LGH Express 4500 (Cutaway minibus) is not roadworthy. LGH is the fuel friendly 'detuned' DML - 260hp instead of 365hp 160K runs well, cranks instantly (when it cranks)... has intermittent black-outs - coast and park on roadside a couple of minutes and it cranks again... that's dangerous and needs to be fixed. The [ short nose/van dog house setup ] is murder on accessing anything without taking apart the house(roof, walls and foundation) to reach anything. ...and a lot of this stuff requires new fasteners since they don't survive dismantling!!! I am definitely contemplating turning the front-end into a removable GLAVAL-like reverse hood/fenders style, so the engine can be accessed freely! REGEN: One thing about the manual regen tools (CTS 2-3) I do not like is that the engine is made to run at high rpm while standing(no load on the engine); I think is a bad idea. I once had a magnificent Pontiac Bonneville, that was used but could be placed on a dealers lot and sold as new, 55K miles. I made the mistake of over-caring for it and let a shop run the-horrible-giant-stinking-cloud-loud-as-smitten-engine-racing-as-if-is-going-to-blow-up-process, trusting the procedure is ok, as it is recommended periodically... within 6 months the engine blew up... a perfect car I had driven for years with ZERO problems! not even a light bulb... yeah! 'pissed' does not come close! I say much better to do this under load, vehicle on an express-way with little traffic! SCANNERs: OEMtools - Connected Automotive Systems carries a scanner that is laptop based(WIN10) oemtools.com/about-us/ Is it overkill, will the tools in this video suffice? I am wondering how that compares to the scanners mentioned in the video? Anyone ? who might have info on, knowledge on that? CTS original no good!? CTS 2 and 3 good for regen... I would never do under no-load. Edge does that see all issues in all modules? Is it bidirectional besides resetting codes? ...good to clear the limp code, as temporary rescue. Hmmm! If the Edge ends up costing an arm and a leg, why not get a Thinktool Pro S and have it all? ...or the OEMTools solution?
Wanted an LBZ , but ordered a 2022 f250 instead. I’ve Heard some horror stories on these too already. It’s mainly emission crap , but don’t want to void warranty already. Love your videos man 👍🏼 The ending clips were great
This is a great video, if you would do another diesel talk video it would be greatly appreciated. I found the information from the video was very helpful.
I work at a dealer and we get a lot of trucks that are seriously fu$$ed because of local private shops. Our diesel mechanics are good dudes for the most part. I support small businesses but where I live most the private shops fit the negative stereotypes. It's unfortunate.
I have a duramax with Allison transmission, I have 90,000 miles pull a 14,000 lb 5th wheel. Absolutely no problems, I do keep up with maintenance but it has been a great engine and transmission. 2010.
I Will testify to the CP4 , 107k miles it decided to die on my on the side of the road 12K to fix that plus all the tows and owing friends beer for help. I got the cp3 conversion good information guys
Is there anyway you can help me out with mine Durmax? I seen where you done a Veterans pick up and it was awesome. Thank you for all the help you do. God bless you Chaplain Dale Stearns
Talking about the TCM fault mine was when I went to go crank my truck and it wouldn’t fire just crank over. Had a crank sensor fault and and TCM fault. Come to find out my crank sensor and MAF sensor was shorting out the system. Had both replaced and no more issues.
I recently replaced my engine and all injectors in my LLY. Would love to see a video on what to do with the break-in and any tuning updates that may need to be done.... Thanks from Dallas...🤠

Have not had that problem again for over 200k now and I didnt have to cut the harness to fix it.

@@jredd801 This was my first 6.0. I've literally had zero problems with it in this first 5 years. I still have an old '93 Chevy 2500 with the 6.5 turbo diesel. But it's a manual trans, mechanical injection pump, zero emissions regulations..the way they should be! 375,000 + miles
I have a 02 with 298,000 on it an 3/4 of them miles are towing a 32' gooseneck, injectors, front end rebuild, rear axle seals an now a new key switch ignition, an another set of infectors, only things done, more fuel, air, tuned has been a good truck.i bought with 20,000 on it. Always carry a spare belt an one or two idler pulley in the tool box
All great stuff 🤘🏼
LMM owner here, and love my Edge Insight CTS II monitor. About to start a project with some hardware from ProFab, HSP, and a couple other things. Can't wait!
Wow. I can't believe I've never had ANY of these "common problems".. 07.5 lmm, 192,000 miles.. I must not haul enough or beat on it.. lucky me!
If you have the time you should make a video on each model and the common problems with each as well as some of the benefits to each model
Awesome video! I own a LLY. I've replaced so much stuff, including the HSP bundle kit. These trucks are not cheap to own!
You got that right
I have had my LLY since May 2013 with 178k miles.....the only major problem was a fuel regulator switch 2 weeks after I bought it. The dealer charged me over a $1000 for the repair. That's the only major problem I've had.....now have 296k miles with just basic maintenance. I love my LLY!!!
@@danielellis2271 I had the same deal , pressure regulator replaced it myself also did the water pump and my egr cooler was plugged up nothing easy to fix but not to bad if you have some ability.
I got an alarm on DEF. My shop replaced a sensor upstream of the regen box because it was wasting diesel. It would not reset the panel. Turns out the outlet sensor was slow to react and had to be replaced to allow the panel to reset. Took my shop almost 2 weeks to hunt this issue down.
Test drove a 2009 GMC Duramax the other day with only 70,000 miles on it and previous owner only used for towing 5th wheel. First time I got on it check engine light came on and transmission was stuck in seemed like 3rdish gear. Dealer called next day and said low battery caused the issue. Ever heard of this?
Very helpful thank you guys I know where my oil and smoke is coming from now😊😁
I don’t have a duramax but I like them all, they all seem to have problems, I appreciate the knowledge you guys shared 👍😁
Thanks
I would love an lly hour. Trying to learn how to make my late husband's 05 c4500 last forever. He loved that truck, only has 50k on it. Found your channel about 3 weeks ago and love it. My dream is for you and Ryan to work your magic. Keep up the awesome work!
My son and I each have ‘03 LB7s in mid-200K’s. I did fuel injectors and lift pumps on both (tough work, but I’m not a mechanic and I got it done) and they’re both strong trucks. Yes, old diesels need maintenance, but few gas trucks will last this long at all, and the LB7s get great fuel economy compared to gas. If you don’t want to but a new truck every 10-15 years, diesel is king.
I have a box stock LB7 I tow with. Would love to see more on potential problems, and performance upgrades that will improve my life on the highway.
Oh yeah! Had mine go out 50 Miles from home. TCM is a must when your Duramax is completely different and not shifting and All 🏁 Great information video thanks Brothers 👍
Can you do a break down of each year of the Duramax’s? Pros & cons of each Duramax engine?? Love the videos, keep up the great work! 🤘🏻🇺🇸
if you go back into his channel he actually has a video on that its just down the list quite a bit but its a great video full of information.
Thanks
@@TruckMaster what you think about the 3.0 duramax ? I try to decide between 5.3 or 3.0.
You should make a video on just LBZ Duramax. That one would be great !
Great info!! I know there are many videos out there, but knowledge is power. It would be great to have engine specific fixes (LMM, LBZ, etc)
Keep up the good work!
Thanks
Love that my 2010 Dodge Ram 2500 Cummins 6 speed manual doesn't know what word issue means. Never left me stranded and it proves it's reliability!
Thanks guys for sharing all your knowledge , I do know my way around
Non diesel cars , but I don't know much about diesel.
I have adquired a 2006 duramax that I plan on fixing up as a father and Son Project .
Thanks again keep up the good work.
And you guys got all my support.
God bless.
Thanks for the video! Hey, do a video of the same and talk about the LB7, LML, LLY, etc.etc, and discuss the vulnerabilities and the advantage of each! And, include the L5P, that's my new baby!!
Thanks
Ill never understand why manufacturers don’t mount ecm and tcm in the cab somewhere. Heat and cold cycles are horrible on computer equipment.
Own a 04 LB7 since new ,use Howes fuel conditioner since new
276k on the truck , still running factory injectors , no smoke , no fuel in crank case , always use the best fuel filters every 10k .
Great truck
I own 2 Duramaxes, 1 is a 04 with over 260,000 miles zero engine/gear issues, the other is a 15 with 120,000 miles, installed lift pump, converted CP4 to CP3, had exhaust issues twice, problem fixed now, no more issues.
Great video guys. Keep em coming ! I carry a new spare serpentine belt in a sealed plastic baggy. One time I started the truck and heard a big whummp and my belt broke. Turned out a squirrel was in there. May he rest in peace, or two pieces I mean.
Ha. I love animals, but that squirrel got what it deserved.
Great video guys!
I would definitely like an LMM specific video on Fuel Pressure issues and Limp Mode. I have almost a million Kilometers on my 2007.5 stock and only started having problems recently. Got rid of the old exhaust and put just pipe and muffler on. Runs much better now but still goes into Limp Mode a lot due to Low Fuel Rail Pressure.
Put a lift pump on it like FASS or AirDog. It’s leaking air into the head unit of the factory fuel filter primer pump. The gaskets get old and leak air and drop fuel rail pressure and put it into limp mode. Replace those gaskets also.
@chip7522 if I'm not mistaken also check your fuel lines. They like to kink especially with that much use and time on em. But lift pump like you said will just make his life better.
@@zacharyhernandez1483
Hi Zachary, I did replace fuel lines several months ago and made no difference. I am also in the process of replacing small lines on top of engine compartment now. We'll see what that does I guess.
Yes! LB7 is king! And yes more on the Duramax!
I have a 2002 GMC Sierra 3500 with 310,000 miles and I love it it’s been a great truck very reliable it has plenty of power almost daily I pull a trailer with it
Hell yeah brother!! Great vid. I will definitely watch this more than once…
I did a cp4 repair under warranty and we had 10k in parts under warranty. Just got rid of mine and it was like a weight lifted off my shoulders. lol
Nice 👍
Bought my first Duramax a few years ago now and have to say, the most vital thing a new owner can do is watch your channel religiously, that’s no BS.
You guys nailed it on this video, I’ve had, and more importantly solved every single issue you’ve covered. Would have dumped enough money to buy another truck had it not been for your videos showing me how to deal with all of it myself.
Thanks for the awesome support watching the channel and good luck with the truck 👍
Undersized radiator on some models , big one !
The Dorman comment is spot on !
much appreciated guys and yes! please toss out some more videos
Thanks for the tip on the idler pulleys, bought new ones and replaced them and yes 162,000 miles they were at their end of life
👍
I wanna hear alot more about lml’s please
LML LIST'S P L E A S E, EXAMPLE: "5 RECOMMENDED UPGRADES" "5 MUST DO'S" PLEASE
Have a lly dually, pressure release valve was releasing at 13000psi causing limp mode. Truck is stock. Replaced fuel pressure regulator and replaced fpr valve with stock piece. Still got limp mode. Now replaced fpr valve with blank plug. No more limp mode. Discovered that injector pump has built in release for over pressure so a second fpr valve not needed. This only works for stock built engines not modified engines. Truck now runs like new.
I've got a low mileage 67k 2015 LML Duramax. Have went into reduced power mode twice towing heavy with no warning. First time was a bad DEF temp sensor at 45k and second time was 9th injector failure at 65k. I was able to clear the code a couple times each and drive to my destination. However both times were freeways speeds on grades with traffic. The pucker factor is huge when you hear a ding, get a reduce power message and go from 70 mph to 20 mph right now.
Love my lb7. That throaty sound. Just wanna upgrade turbo to a 64. And build my trans.
That’s a great plan
Putting a monitor and wrench kit in the truck. My 2019 Duramax is still pretty solid, But I like your ideology on fix it before it breaks!
I have a 2013 one ton dually I live in east Lansing Mi it has 97000 miles about 23000 miles we pulled a Airstream trailer it weighs 6600 pounds. I’m very impressed with you guys maybe once good weather comes around I will make a appointment and have do some PM thank you 😊
I love the Duramax talk especially about the older models in 2005 she been talking about the 2006 is and 2010s I'm looking at buying me one so I need to know as much information that I can possibly get cuz I own it a Ford and they kept on breaking down the 6.0 the 6.2 the 6.4 stayed in the shop so I'm looking at a GMC instead of buying a new model 2020 I rather work with a older model and do majority work myself instead of being in the shop all the time and upgrade that engine like I want to so I appreciate everything you talking about continue to do what you do doing a wonderful and amazing job
Love this type of video, I have a 02 lb7 with 192000 on it . It still runs good but I'm getting nervous. I've owned it 8 years and never had one issue so I know something is coming. Its completely stalk other than a 2 in suspension lift.
I'm at 210k injectors and upgrades!!! Rebuilding the front suspension, it wasnt sloppy but is 2002 with 210k on it lol. No problems here!!!
I had a 98 6.5 for 11 years. No engine or transmission problems. Bought an 01 lb7. Needed new injectors 3 mo later. Truck was under 140k miles.
I’m an owner of a 06 LBZ . With 46000 miles ? Thank you I appreciate!
I like your comment about buy a gas engine. I think the consumer grade diesel engines are such a rip off. They are too complicated for the basic mechanic, parts are way to expensive. These trucks are not reliable. You are almost better off buying a class 6 or class 8 truck. It will get the same mileage. The fact that the industry is forced to try to clean up the exhaust can add $10,000 to $15,000 operating cost over the life of the vehicle. I am a fleet manager. I have lots of Power Strokes, Duramax..... Sorry, that's just my opinion.
I’m expecting delivery of a new Chevrolet 3500 High Country L5P powered dually next month that I ordered in March and a dual remote oil bypass system from Amsoil first thing and then figure out what the best route of tuning/deleting to go but look forward to the journey and getting all the knowledge I can gain in the process!!!! Thanks for the videos I have gained a bunch of information right here already!!!!
Oem fuel filter housing issues. I went through it and ended up adding an LP. Best product I’ve bought for my truck aside from my insite.
LML Duramax, deleted and tuned thought had ECM/PCM issue, no comms with OBD scanner at times/ stabilitrak, traction control on dash and no crank. Was almost certain ECM was bricked and was going to replace when I took off driver side wheel well and just moved the engine wiring harness around and then the truck would start. It was intermittent and an electrical automotive shop already replaced the fuse box on the driver side a year before for the same sporadic behavior while driving. I used to think it was a fuel rail pressure or fuel prime issue but it was electrical all along. The company that made the tuner is out of business, my concern was replacing the ECM and having to have a different tune installed that's supported because of the EGR delete... Thankfully its not the case, hope no one else has that issue with the engine harness
Everything you can give to preemptively do I want to hear. Thanks a ton! 👍
Hello again Guys!
Thank you for the reply. I should have mentioned that I already added a Lift pump and it still does the same thing. I also eliminated the filter pump and new seals. Again, same issue.
Bob
Thank you for the information on all duramaxs. 04.5 lly owner(inherited,and happy!) I've learned so much from you. Really want to work on trucks,especially duramax. Subscribed to both channels to keep up.
I always love diesel talk I hope you guys make a nother video on the Duramax I like to have the knowledge of what to expect if something happens with my truck
2012 Lml...low miles 85k, I've had most of those issues, nox, pipe, def heater, and TCM. Also a big thanks to Ryan's for the TCM shipped to Texas. What was the Bosch CP4 plug for insurance?
Awesome content!! I always like this kind of information, so that I can be prepared. Thank you both for sharing the knowledge. Please do more videos on these topics. My LLY and myself will be happy.
Roger that 👍
I want to know more about LB7 Duramaxs and problems please
The main lb7 problem is injectors. Air gets in em and the body of the injector cracks and dumps diesel into the oil. A good lift pump solves the issue
Good video.. How bout you do a vid like this with the truck that started it all...2001 LB7 with all its quirks and phantom limps..limps with codes..2001 factory programming issues..etc..etc..
I have a 2013 LML. It has a mini max and deleted with 4 inch exhaust. When I first bought it it would run like a scalded dog in performance mode (like spin the tires at 60mph when punched kind of fast) I have since added an air dog 65gph lift pump, egt and tranny temp gauge and exergy fuel system saver and have now noticed it doesn’t “seem” or sound as fast, it still runs fine as a daily driver though and for towing but won’t spin the tires at all (I did put new tires on though so that may be part of it) . It Also it used to make a loud hiss as it cycled the turbo during start up that now doesn’t do it as loud at all. I am leaning towards either time for a new air filter (or has the AFE power air filter) or maybe some metal shavings got into the turbo when I drilled the exhaust for the egt probe...or it’s the fuel saver (I’ve heard others say they removed them because it robbed power). Anyway, what are your thoughts on this? Thank you in advance.
Transfer case pump rub up through the 07 Classic.
Leaking power steering and transmission lines.
Glow plugs LBZ.
Seals in the fuel filter heads after a period of years.
Hearing all these problems with electronics and emissions systems. makes me love my 12v with manual transmission even more!
I have a 2005 Duramax LLY, I remember because it reminds me of “Lilly”… I have 206,000 miles pulling a 10k lb 5th wheel trailer and now I’m having issues overheating while climbing hills in hot weather. I had to pull over every 35 miles as my engine overheated and low cool warnings came on. I drove 150 miles adding about 10-12 gallons of coolant sometimes after only 5 miles. I made it home but realized I blew a head gasket which I’m not looking forward to paying for the repairs. Just FYI. Time for a new truck I think.
Here is another tip on Duramax cooling systems. You are dealing with a lot of aluminum in the system. Its highly susceptible to corrosion. You want your coolant to have a neutral PH. Most tap water water is acidic. Distilled is the best. First off get rid of that red coolant!! That garbage clogs things up. Second, after switching to green, put in 2 bottles of Napa Cool 4056. It will stabilize your coolant PH. I have taken out water pumps and not had to change the housing because there was no corrosion on systems that were neutral. You can check your PH with a guage or litmus paper that you can pick up at any plant store.
Gonna be on the road so will take off with all sorts of preventive items.
...some of the stuff in your description that was used on the truck Mods.
...and tools, spare parts, rescue stuff, name it. TCM definitely.
Was going to get the GM TECH 2, but now I have seen this video, I am holding off.
I am new at this shtuff, thankful to get any information to consolidate my understanding. ...aware of the CP4 Achilles' heel! ...and the fuel pre-filter issues, and how bad fuel can destroy a DURAMAX!
My 2011 6.6 LGH Express 4500 (Cutaway minibus) is not roadworthy.
LGH is the fuel friendly 'detuned' DML - 260hp instead of 365hp
160K runs well, cranks instantly (when it cranks)... has intermittent black-outs - coast and park on roadside a couple of minutes and it cranks again... that's dangerous and needs to be fixed.
The [ short nose/van dog house setup ] is murder on accessing anything without taking apart the house(roof, walls and foundation) to reach anything.
...and a lot of this stuff requires new fasteners since they don't survive dismantling!!!
I am definitely contemplating turning the front-end into a removable GLAVAL-like reverse hood/fenders style, so the engine can be accessed freely!
REGEN:
One thing about the manual regen tools (CTS 2-3) I do not like is that the engine is made to run at high rpm while standing(no load on the engine); I think is a bad idea. I once had a magnificent Pontiac Bonneville, that was used but could be placed on a dealers lot and sold as new, 55K miles.
I made the mistake of over-caring for it and let a shop run the-horrible-giant-stinking-cloud-loud-as-smitten-engine-racing-as-if-is-going-to-blow-up-process, trusting the procedure is ok, as it is recommended periodically... within 6 months the engine blew up... a perfect car I had driven for years with ZERO problems! not even a light bulb... yeah! 'pissed' does not come close!
I say much better to do this under load, vehicle on an express-way with little traffic!
SCANNERs:
OEMtools - Connected Automotive Systems carries a scanner that is laptop based(WIN10)
oemtools.com/about-us/
Is it overkill, will the tools in this video suffice?
I am wondering how that compares to the scanners mentioned in the video?
Anyone ? who might have info on, knowledge on that?
CTS original no good!?
CTS 2 and 3 good for regen... I would never do under no-load.
Edge does that see all issues in all modules?
Is it bidirectional besides resetting codes?
...good to clear the limp code, as temporary rescue. Hmmm!
If the Edge ends up costing an arm and a leg, why not get a Thinktool Pro S and have it all?
...or the OEMTools solution?
Wanted an LBZ , but ordered a 2022 f250 instead. I’ve Heard some horror stories on these too already. It’s mainly emission crap , but don’t want to void warranty already.
Love your videos man 👍🏼
The ending clips were great
Im a life long chevy driver i drive a 02 last one built in usa
Have you/how many times have you done injectors?
@@jonnyg9330 I have an 03 LB7 with 280k and have only replaced the injectors once.
This is a great video, if you would do another diesel talk video it would be greatly appreciated. I found the information from the video was very helpful.
I own a 2008 with 800,000 miles pulling RVs to dealerships. Best ever!
Lost the serpentine belt on a lly when the power steering pump pulley came off. It is now secured with a bolt and a series of correctly sized washers.
I work at a dealer and we get a lot of trucks that are seriously fu$$ed because of local private shops. Our diesel mechanics are good dudes for the most part. I support small businesses but where I live most the private shops fit the negative stereotypes. It's unfortunate.
I replaced mine before having issues, thanks for the piece of mind!
I have a duramax with Allison transmission, I have 90,000 miles pull a 14,000 lb 5th wheel.
Absolutely no problems, I do keep up with maintenance but it has been a great engine and transmission. 2010.
Excellent video. I have an 01 Duramax with 80k miles. Love it.
I don't own a truck with a Duramax diesel but I'm getting ready to buy one so I found this video in good time
I Will testify to the CP4 , 107k miles it decided to die on my on the side of the road 12K to fix that plus all the tows and owing friends beer for help. I got the cp3 conversion good information guys
Love your videos I'm a Duramax first one I've had.
Thanks Dale
Is there anyway you can help me out with mine Durmax? I seen where you done a Veterans pick up and it was awesome. Thank you for all the help you do. God bless you Chaplain Dale Stearns
Talking about the TCM fault mine was when I went to go crank my truck and it wouldn’t fire just crank over. Had a crank sensor fault and and TCM fault. Come to find out my crank sensor and MAF sensor was shorting out the system. Had both replaced and no more issues.
Post more lb7 content they are “king” as said
I have 280k on my LB7 and love it!
I recently replaced my engine and all injectors in my LLY. Would love to see a video on what to do with the break-in and any tuning updates that may need to be done.... Thanks from Dallas...🤠
