the nv4500 transmission behind the cummins diesel does suck! without proper upgrades and updated parts! here is what failed on my nv4500! from my 98.5 cummins dually 4x4
![SPECIAL TOOLS NEEDED - NV4500 Transmission Teardown Video [CHEVY MOPAR]](/img/1.gif)
I'm taking a wild guess Im thinking with driving it like that for awhile possible the chunk of fork did the gear in. Then maybe that's when the splines got loose on the shaft. Gotta think that cover is not very big and road bumps or reversing could have moved that chunk around in the back and it made contact. Then with the diesel engine torque it crunched it in the gear a possibility. I see welds too on the ring not great welds but It does work to keep the ring on.
I would agree with all of those, but I do think the splines being loose was my oringial noise problem then it got worse from there lol
@@floridafenceland1137 i am getting nv4500 trans and planning to tac weld the 5th gear retainer.
Anything else you recomend?
I would do that for sure
@@FirstLast-tx3yj updated shaft, collar with the allen bolt and tack weld it. Should be good. Also don't lug the transmission, keep it above 1600 cruising
Regardless of this videos title, the NV4500 is a great transmission! What sucks is people's driving skills or lack thereof. Pretty apparent that the previous owners rode it hard and put it away wet! Lugging the engine in 5th (especially while towing) is the biggest cause of 5th going out. You don't even need to use the clutch with an NV4500 if you know how to shift properly. Mine just rolled over 250k, has towed in excess of 24k on multiple occasions and is still going strong 😎
Just bought a dodge with a built 5.7 for my bussiness. Thing tows 6 golf carts without a second thought. Shifts fine, first pops out sometimes. 210k miles.
It’s easy
Whats about the KM145 86 5speed
@@travischaddock4826 You have a Ram 2500 with a Hemi and a speed? I thought I was the only one.
@@DobermansRock i did. I sold it when I closed my business. It turn 37x13.50 tires pretty well. Never used overdrive though, inputshaft bearing got pretty bad but it got a leak and ran low on fluid for a few months til I noticed.
People never fail to amaze me. There are people out there that no transmission will ever hold up to. I dont care what it is, if you’re hard on it, it’ll break.
Pretty sure this is a solid transmission. Mated to everything from a 4.3 Chevy to a 12v Cummins and even ready for a Chevy LS.
It is a fantastic transmission.
Years ago my 5pd went out after 289000 miles on it. The failure was a ball bearing assembly breaking and dumping the balls into the oil and the gears got chipped up and the primary shaft got out of round.
I rebuilt myself over 2 weeks in my garage and the parts were purchased from the dealership for $800.00.
Truck is still on the road with over 357000 miles on it.
My next project is to rebuild the motor.
Great trucks 🛻😃
do they suck because you want a transmission you never have to put new oil in?
OH SO TRUE SIR BLACK
MUCK DRIZZLING OUT THE BOTTOM😆🙄🤣🤣 I HAVE ONE WITH OVEE 400K ON IT N IT'S NEVER BEEN OUT OF THE TRUCK
Looks like pretty thin oil too, not the 75w-90 synthetic recommendation
“ IDK how the teeth broke off!”
Said every kid that abused their car!
The reason why I rebuilt mine was because I wanted to rebuild it to a higher standard than a cheapo shop rebuilt unit . So that ment a new bigger imput shaft , new updated 5 the gear and retaining system. Also the best bearings and synchros I could find, still only cost me 1100 ish.
Funny thing is, new venture is not a dodge transmission, it was USED by gm and dodge. Actually it a pretty good transmission if has no fifth gear nut issues
The NV4500 is an awesome transmission, where people do the most damage is when changing the oil like in this video it's so obvious you have the wrong oil in it. Another bad decision people make is when pulling a load they will run 5th gear lugging the engine that's what tears out the 5th gear. These transmissions have a lot of brass in them, 90W gear oil is the worst thing you can do to it, a lot of your parts houses will tell you the synchromesh oil is what you're supposed to do, another bad decision Synchromesh oil is definitely the wrong oil. The GM 75W-85 GL-4 is expensive and is NOTHING like synchromesh oil. Synchromesh is basically 5/30 synthetic motor oil, not good in the NV4500. The ONLY substitute for the right GM oil is Red Line Synthetic MT-85 it is the exact same stuff. This oil is almost clear, and trust me put some on you finger and do the same to the other hand with regular oil you will feel the difference.
I run royal purple 75w-90 in mine, no issues with wear. Had a leak and the input and counter shafts ate each other. Synchros still look like new, but replacing them since it's torn apart anyway.
If the 5th gear nut is fixed like mine was. A nv4500 is a badass transmission
I agree 100% bud!
The NV4500 is barely adequate behind a 4.3L V-6 gas engine. With updates they are fine behind a small block gas engine or a stock 160HP 12V Cummins. Any more torque than that chews 'em up and spits out the pieces, just like this one. 5th gear isn't the only failure. They are known to clean the teeth off 3rd gear as well behind anything more than a bone stock 24V.
Yeah I could see that happening for sure
Greg Pierce whatever
@@gregpierce5296 Yeah, towing 32,000 gross every day on the NV4500HD with 453,000 miles on it. All summer long towing my backhoe around from job to job. Yeah, horrible trans lol........... See if a ZF5 can do that.
The nv4500 is a very good trans and it came in not only dodge but gm products. The only real weak point it 5th gear and 90 percent of issues are with the diesel when doing alot of lugging the engine in 5th gear. Got my 98 dodge fairly cheap cause 5th gear was gone. Replaced 5th gear about 10 ys ago in 1 day with soecial retainer and has served me very well ever since.
This guy probably think steak and money sucks too.
Yeah
That trans was rebuilt by some grade school kid. Thats your first problem. Second one is the wrong oil was put in it. You don't use 90W gear oil in an NV4500. It takes a special lubricant. Third problem is, and I speculate here, F F & L probably lugs his diesel at too low an rpm. The power strokes at low rpm act like a big impact wrench on that retaining nut. The title of this video is what really sucks.
N.V. was a partnership company of Dodge & G.M. That G.M. & DODGE & others contracted with? That is no longer in business. Today FORD & G.M. designed the new 10 speed automatic & have agreements.
I have the NV4500 behind my 04 6.0 gmc 2500hd, and I’m starting to have trouble with shifting while it’s cold.
raider42day switch your oil to redline MT-85.
Hope you followed previous advise, MT-85 is your oil
lol ive been driving around for a few months with a nasty growl coming from 2nd and 3rd in my 94 12v, just waiting for the day it completely grenades itself haha, very informative video thank you
Hahah yeah mine was bad, I just let it go til I couldn’t anymore lol
I have a 94 12 valve and 3rd grids real bad going in and 5th makes a nasty noise while cruising
Wtf are you talking about. Nv4500 is one of the best.. and is not only in dodge trucks... should re-title "why I dont know how to run my shit right"
😂😂😂
@@floridafenceland1137 over 400,000 on my oldest unit untoutched haha. Scoff at that goof, these things make me money everyday
That’s funny, My 12 valve has 500,000km and the 5th gear is just fine. You don’t tow in 5th, and you don’t lug the engine in 5th under 1250rpm.
The automatic sucks.. manual is the way to go! Especially on the 5.9 Cummins
red neck work table. If you get an old lift gate truck you can fix lawnmowers on it too.
Dunno man, I've got one with 300,000 miles on it. I wouldn't call that sucking.
We may have been able to buy it cheaper before but now good luck trying to find an NV4500 4 less than 3 Grand without a core charge my rebuild is 2500-3k
So true man
they aren’t meant to be romped on. you try to drag race this is what happens lol
like they are clearly stated to be one of the toughest if you drive it like it should be driven
Drag race in 5th gear? In a dually? Yeah that’s what I was doing
Wayyyyyy cheaper to rebuild yourself than to buy a new one. $500 to rebuilt vs $2000 new. What ones cheaper? I’m pikckin $500 all day
I have no clue what I’m looking at but your pretty cool
Thank you!
Mine is a 99 5 speed but no issues, 185,000 and no leaks even the axles .🙏
Idk NV4500s are one of the toughest transmissions out their, but some get unlucky. Change out the fluid at proper intervals and don't tow in 5th gear, simple.
I'm at 2000 rpms in 4th gear at 60 mph, what more could you want? Cummins will sit there forever.
If your truck doesn't have a 3.55 rear end then we'll Oops. Some people out here running 4.11s which force you to use over drive, that kills them.
Yeah got one in my 95 cummins with 342,880 miles on it Yeah they suck.
Mine is just fine and rolling on 370k miles with zero issues 😎
Mine Didn’t make it this far lol
@@floridafenceland1137 have been really dang lucky hahah
So you buy the updated shaft rebuild it and never look back atleast they make a fix.
Yeah I just replaced the whole trans
Gm used th nv4500 with the 6.5 turbo diesel. It was great for me. Never had a problem. It lasted longer than the engine.
Put them behind the 350 too in heavy duty trucks.
You do realize the NV transmissions aren't made by dodge right? Dodge Chevy Ford even Toyota used them. All same trans different cases/tails/bell housing.
Yes of course it’s click bait
I think it is the way the driver drives. Haha my opinion. My '01 speed still good haha
3:37 he became Venom
don't lug in 5th gear below 1500 rpm, dont tow in 5th even unless flats really
So witch is the beast kinda transmission for a 2nd gen Cummins cuz the 47 an 48 re suck. So NV4500 or Allison 1000 NV5600, G56. What is the best my transmission is fucked my cummins wont even move so plz I have no clue what to go with so can you help with some options Manuel or automatic.
I would stay away from auto, but nv5600 or g56 are top dog!
@@floridafenceland1137 an one more question , on a diesel manual do u have to down shit or can you go from 40mph 3 gear an just throw it in N to stop?
Just get an nv4500 and don't drive it like a dumbass, nv5600 are expensive and have the same final drive, it just gives and extra gear, did I mention they are expensive?
Owner fualt not the transmission , do lack of maintaining and you keep driving it when started making noise.
Maybe change your oil once inawhile
Oil?
Nv4500 when they are updated, they ain't too bad(synchros STILL SUCK) but if they are stock....🤮
Happen to know where I can find one of these transmissions for cheap? My dad has a 2000 dodge ram 3500 that has a automatic transmission. I'm looking for at least a 5 speed to see what's out there.
I’d look at Allstate gear.com
Good luck with that.
What motor are you running??
Hey man. You ever done a head gasket fix on a '01 ram 1500. Any advice? Or vids? Haha
I haven’t at all man I’m sorry!
Biggest question I have is what oil should I use for a nv4500? Seen a lot of controversy on this.
I think I used 85-140 in mine
@@floridafenceland1137 My question was more in respects to the brand of oil, i've used royal purple 85 -140 but i've heard you're supposed to use a certain make of oil. The oil from what I can tell is not provided or produced anymore.
No controversy. Redline MT-85 is the only lube that matches the Castrol Syntorq LT. It's actually better than the Castrol, IMO. My 4500 shifts better with the Redline than it did with the Castrol, and it shifted great with the Castrol. Even GM recommends using MT-85 in the NV4500. If a 4500 gets a fluid change or repair at a GM dealership, that is what they fill it with. Not sure about Ram dealers, but I'd be very surprised if they didn't use it.
@@WTFChuk Thanks for the help! Gonna write this down for later use...
Amsoil makes one for NV4500 specifically
It's not only dodge and the 3500 is worse
Do the nv4500 have oil pump of any kind?
They do not the gears them selves along the oil around
WHY ❓ THEY DON'T NEED THEM THE LUBE CHASES UP THE GEARS WHILE IT'S RUNNING OR IT'S SELF CIRCULATING
Great video. Thanks 👍
No problem! Thank you!
What did you end up doing with the trans?
Sold it locally to guy
Cummins make that transmission??? or does .. new process ???
New venture makes it
who does work like. i thought my truck was the victim of the worst jack leg in the world. but yours is even worse.
😂😂
@@floridafenceland1137 just pulled mine today. got bad sincrenizers, gonna put overhaul kit in it. 98 k 2500 350 cid
This isn’t even that bad 😂
It's dead, Jim.
She gone lol
Good luck ever getting one of those to hold together I went through 9 of these transmissions in my dodge when I was hot shooting I was under cdl so under 26,000lbs and I never got one to go past 40k miles. I was also only 275hp not all turned up like most these guys. Yes I had full splined mainshafts and tryed all the different style nuts I even tryed a slip on nut retainer that does behind the nut only to destroy my transfercase because it came loose and put pressure on the input on the t case. What a joke of a transmission. If I wasn’t blowing 5th up I blew up 3rd gear and has countless bearing failures even with the dang pto coolers and still being over full of fluid. It the nv4500s defense I was running a 4:10 truck so it was in 5th 90% of the time.
Oh ya most the time the nut never came loose It usually chewed the gear up due to the bearing on the main shaft going out due to lack of support
Good to know, still Going strong but I’ll Keep that in mind
Swell. I have one of those same retainers on mine. I am swapping to a 6 speed Allison before the end of the year. I hope the retainer doesn't break and wipe out my t-case before then.
Keith Miller aWell there’s your problem lady. Running in 5th while hotshotting a load of cars....
@@prevost8686 the problem is that the trans is a crap design. All the gears need to be inside the case, between the support bearings, not overhung off the back side. Also, the 5th countershaft gear should be pressed on to splines and constantly driven just like the 3rd countershaft gear. 5th speed gear should run on needle bearings like the rest to the mainshaft gears, and engaged to the mainshaft by a conventional slide coupler arrangement. It would have been simple to combine it and reverse with the same coupler being as they use the same shifter rail.
Instead of doing the above, they tried to cobble a 5th gear onto the ass end of a 4 speed trans. The result was predictably dismal. They have an adequate life span behind a gas engine, but the large torque pulses of the 6 cylinder diesel just beats the pitiful 5th gear to death.
An ole boy told me about his truck I believe he has a old chevy 3500 350 4 speed he told me the nv4500 was made by Mazda and we all no Mazda about being kinda cheap
Yeah it was made new venture, deffinetly not mazda
Made by new venture. And they're 5 speed not 4.
@@trevenjones7168 it was a 1990 they started using the 5 speeds in 1991
@@oldcroneysgarage9739 an nv4500 is not a 4 speed and absolutely not made by fuckin Mazda
supersticks!
Only way to go bud!
fifth gear nut comes loose fix it and dog clutches go out next and once again no 5th. even under best treatment bearings and syncros go out around 300k miles. Just too much torque from diesel engine
I agree would rather have a g56 but oh well lol
Donald Tinney 300K behind a diesel isn’t bad.
holy crap
Yes it was so bad!
She was borked
Big time lol
Oil bath
Still A LOT better than an automatic haha
You are 1000% right
I have one with 380k miles on it still pulling a gooseneck hauling equipment and loads of steel almost daily, but I don't drive like a dipshit.....
1998 3500 dodge did all the updates, bought 4 of them. Garbage..
Damn that’s badddddddddd
So bad lol
So true....every trans they came out with was a turd.....just like the....5.7 hemi...another junker
dumb fucking asshole
Your mom
@@floridafenceland1137 I can't remember why I posted that. Probably drunk. But I stand by my word. Was this the video where the guy fucks up his transmission but it's totally not his fault?
I mean the 5th year ecploded and I swapped the trans so idk lol
