Awesome presentation. I havn't had the joy of owning a Beemer with an ZF 8 speed yet, only the ZF6HP28 6 speed and it has been bulletproof. ZF is a great company with heritage dating to the Zepplin. Reliability is the highest priority.
I too have a Jeep GC with ZF8 box, fantastic tow vehicle, dont use 8th gear for towing. I am a little concerned with vehicles with 10 speed boxes and towing, might be keeping the Jeep a little longer
Not at all. So for example lets see how good it is after a running time from 500.000 Miles compared to an realy good Transmission like the World best Japanese AISIN Transmissions. For example i owned also a AISIN 5speed Transmission with 4 Overdrive Gears and it runs, shifting like a pure dream fast, very direct absolutely without shiftlegs. And without any oil changing after 6 Years lifetime. Also Hyundai Transmissions are in the Average decent too, but my 5speed of course not that good as my 5speed AISIN in the drive feeling BUT in the quality my Hyundai Transmission is very reliable and very strong. But i guaranteeing no ZF Transmission will by far not gets the same lifetime like a AISIN there is no Arguing that. With a equal, same maintenance no ZF can mess in lifetime with a AISIN. It starts already with that primitive Plastik pan, ground cover on the ZF 8speed As far i know AISIN doesn't use such a plastic crap for example for the oil pan part. But if such a plastic sh... will may eveen come on ASINS i be sure, than are the Plastik parts from the European, German Manufacturers way way more trashi, crappie than Japanese ones are. This is, what it shows in the history allways in that way. So i don't expecting already here a long lifetime and a maintain less payable lifetime from those ZF crap. Thats normally the way, how it is. Regards Jay
@@JWORLDKINGyou cannot compare smoothness and shift speed to Aisin boxes, ZF 8 is number 1 by far. Most used gearbox in the market for a reason. Same reason the biggest brands use it.
Thanks great video. From ZF service manual: ZF 5-, 6-, 8- and 9-speed as well as the ZF 4HP20 automatic transmissions are filled maintenance-free with specially developed semi-synthetic ATF oils. However, due to the many factors influencing the service life of transmissions in individual operation, ZF recommends an oil change after 150,000 km for its transmissions. In operating conditions with high temperatures and loads, or with unknown vehicle use in the past, it can make sense to change the transmission oil at shorter intervals. In each case, only released ATF oil may be used for oil changes. And oil changes must be performed in accordance with the relevant specifications. The exception is the ZF 5HP18 automatic transmission which must be filled differently depending
I have this transmission in my 2012 BMW X5 35i and it is extremely smooth but yet if you need it to turn into a quick shifting performance machine you can slap it into sport and it transforms it.
8hp has been in service in the 3 series for 8 years but it came out a lot earlier. First application was in 2008 7 series. Basically came out at the same time gen 2 6hp came out
Definitely agree that this tranny is a keeper. I'm a 20 years experienced tech and I have one in my 2013 ram 1500. Not one problem with the trans since buying the truck brand new. I've done one full service, changed the pan/filter with mopar and amsoil ATF spec'd for it at around 75k km, and just drained and filled it every 75k km since. At around 225k km now and it drives like it did on day one. I'll be doing another full service soon with a new pan/filter. Nothing required other than the regular maintenance, not even so much as a leak.
@@4-Runner I kept the original from the original pan when I did the first full service. Haven't needed it yet after any of the drain and fills. Could probably just change the O-ring on it if you find you have a leak after removing and reinstalling. The one thing to mention is it's an Allen 10mm I think, but being plastic it doesn't work so shit hot. Use a torx 45, or whatever size fits best, 50 maybe I can't remember, on it to remove it.
ZF is an amazing transmission and shifts very smoothly, and when it comes time to change the pan/filter on my Chrysler 300, I will make sure to get the proper ZF fluid and filter kit! 😊
My BMW Indy changed my transmission fluid and filter with a kit I bought from FCPEURO. It’s on an F30 and I had 80k miles. He commented about how clean the old fluid was. Now to do the E89 auto trans....
My broke at 300.000 km, grooves in one planetary set were torn. It was a common problem and upgraded version of this was installed. It was not expensive at all, together with oil and filter the repair was 1,100€. Now I have 330.000 km and I wonder how many more are there before breakdown. When I first drove this car on a test drive I almost couldn't believe how smooth everything works.
When I ordered transmission kit from FCP, I got also 3 rubber tubes for replacement as well as electric line new sleeve. All replace and works awesome!
I agree the ZF 8-speed is a fantastic transmission, very quick and smooth gearchanges. It was a bit confusing in the beginning where you first very clearly recommend the original ZF filter unit and then later, underneath the car it sounds as if you say you don’t recommend it «because it’s made by Philtrans»…, which is correct? I can buy a kit from ZF or Meyle, where Meyle is actually a bit more expensive. Meyle is a reputable manufacturer, although ZF seems the better choice as the original manufacturer. Also, is there a similar instruction video on actually changing the transmission oil?
We had a 2016 X3 3.5i that went through 2 of these in a month because they would not stop leaking from everywhere. Like they were building up pressure internally or something. Luckily it was all dealer warranty work. Ended up getting rid of it for a Grand Cherokee 5.7 with the same trans and haven’t had any problems with it this time around.
Thanks for this excellent video. I'm looking at buying a BMW with one. Once I do buy my first Euro car, I know FCP Euro is the ~only~ place to consider when buying needed supplies. Again, awesome job!
In Australia we have the 6HP in our Ford Falcons and it was a reasonably common problem where the transmission cooler failed internally, However I have never heard of a ZF gearbox failing without reason aside from the cooler. I would like to know more about the sound they make on their upshift, I gather its the brief unloading of the engine to allow for a safe/smooth shift saving the input shaft, But I would like to nerd out on more information about this and why it happens, and why you don't hear the same noise in other automatics, apart from DSGs - Which the ZF isn't.

The pan I purchased to service my ZF8HP on a 2017 BMW X5 has the latest revision with the white transluscent filter casing. The pan is co-branded Hengst and ZF.
Nice.. What type of car? Might want to get a fluid / filter change done soon. Getting my Q5 TDI done now at 180k.. Was factory. Curious to learn the state of it. Audi saying these were good for "life" but cheaper to service than full replace.
What could cause rough shifting? I notice it most in the middle most used gears. From 4 > 5 > 6 and back. More noticeable with cold engine / transmission.
Great video! Is there a datasheet with the recommended service interval for every fluid, spark plugs etc in one place? If not could you compile one? :) I have a 435i xD with 30k miles and I would love to have pointers on what is next on the maintenance. Thanks!
Great video - thanks... Maybe you can guide me here.. Over the past weeks I have discovered problems with the transmission... Worse when the temperature is below freezing... gets better when the engine is hot and even better shen the weather temp gets higher... Difficult to set into Reverse - have to put it into Drive mode first and then Reverse... When I start drive the rpm goes higher before shifting, and 40 miles an hour with 3000 rpm, does not get the transmission to shift... It's like only the first 3 or 4 gears are being used... Manual gear is not possible... One day is totally crazy - the next day it runs without any issues... Yesterday the oil level was checked and was ok - the oil was dark but not black.. not clear... The car has just turned 100 K miles.. I drove the car to a workshop specializing in automatic transmissions, and they said worst case scenario is a new transmission.... My car is a BMW F31 from 2017 - well seems like a huge expense on a relatively new car.. Any comments/ideas :-) and happy new year to all...
Hey there, a shop claims that they have to drop the entire mechatronic to change that wire sleeve. Is that true? Is it easy to change it? Seems like mine is leaking
Evening guys, I have the 8hp 45 in my 2011 5 series yBMW. I’m suffering quite badly with a very sluggish gear box with hanging onto gears, getting nudges when down shifting esp from 2nd to 1st. I carried out an oil service with new pan and ZF lifeguard 8 oil approx 2 years ago and have since drained and refilled the box twice to try and flush with fresh fluid. The car feels really lazy and is weak to take up torque. It’s done 170k miles now. Any ideas? Thanks
Can you make a video about the transfer-case ? Btw i have the transmission in my bmw , and it can jerk between first and second gear especially when the gearbox is cold. The car has 100K miles and as far as i know has not had a transmission service . Is a transmission service advisable at this point ? ps Love the videos, keep up the good work
This could possibly just be that you’re low on transmission fluid.... I got liqui moly in mine after my trans was serviced. Bottle is about $7 from FCP
100k miles = 160000km. ZF recommend the oil and filter change every 80-120k km. So here it's your answer: do the service! And use ONLY the HP8 oil, not any dexron stuff.
@@thebmwfan Yes, that one is compatible as it has the 9.55550-AV5 certification. To be added to these: Petronas Tutela AS8 / ZF LifeGuard Fluid 8 (code: S671.090.312) / Vaico ATF 8HP V60-0264 or RAVENOL ATF 8HP Fluid They are green, not red.
If BMW had just replaced the oil and filter in my F30`s ZF 8 Speed Auto transmission , they wouldnt have had to pay almost 70% of the value of the car for replacing the transmission that failed . Annoying but gratefull that it was still under its motorplan / Warranty .
I used your video from the X5 8HP service to do the fluid and filter change on my 228i xDrive - messy without a lift but it was a surprisingly straightforward job. Your complete kit was exactly what I needed - I just wish the ZF Lifeguard fluid wasn't so costly. Have you & others had good luck with the Liqui Moly Top Tech 1800 fluid instead?
@@patrickdunn6701 it doesnt. multi vehicle atf meets requirements for more common automatic transmissions like ford’s mercon lv. do not put that in ur zf8. lifeguard 8 is not like normal atf and has different viscocity at different temp points
Here is the thing , No mechanic have found my ZF tranny issues .. * It makes whining noise when pass 2,500 rpms "sound like a supercharger belt" *Some times loss torque just when change from 1st to 2d gear no always * Highway or city speed no issues * Fluid and pan was replaced at 100k miles * Problem starts with 115k miles *Filled with original Mopar fluid All mechanic says never heard that issue
newer (2021+ MY i believe) now have a metal pan with a separate filter. i have tried it yet, but the shape is the same, so you should be able to snag one of those pans and save the $200+ for a pan/filter
@@michaelnikprelaj6679 it's mostly with the diesels, but they are pretty weak with the splines on the rear output drive flange shearing, and the clutches wearing.
Hi, do you recommend replacing the pan with an aluminum one? It seems that the updated pan is aluminum, what are the benefits of replacing it to a more expensive aluminum pan?
Thanks for the video! I have noticed if I start my car F30 from cold, and set off within 10-15 seconds, the first up shift from 1-2 is pretty delayed and sounds like it’s slipping. If I idle for 30 seconds it does not do this. Otherwise the transmission operates normal. What do you think is the problem?
It’s completely normal. Mine does it too and I got my valve body completely overhauled + flushed with 11l of new oil. I heard this from a lot of people and it seems to be normal
I have the same situation on 2017 X5. The service adviser at BMW said it would be to hold gears 1-2 a little longer to warm up the cats a little faster to reduce emissions caused on cold start.
A question to Gareth and the Community: I had an appointment at a ZF service point to flush and change the transmission oil of my ZF 8HP45 after 85k km. My F20 is changing gears like a brand new car since then. However, when the transmission gets hot, it starts to smell quite badly via the air vents. This issues occured right after the oil change. After two weeks it is not gone yet, althoug it has improved slightly. The service staff double-checked the transmission. No leakages were found and no oil was outside the gear box. They told me, it is quite common that the F20 or F10 series from BMW tends to smell due to the fresh oil. It should stop smelling after a while. Have you experienced something similar so far? Thanks.
Great video!!! I have Audi Q7 4M model, from 2015-2021. It has ZF 8 speed automatic transmission. I have 170 thousand kilometers on it. I don’t know if a previous owners done the transmission fluid change. Do you recommend me doing this at this stage? Also, which transmission fluid you recommend, original from Audi dealer or ZF one? Thanks for your reply 😉👍
Wish all videos were as well explained! I have a 2016 Audi Q7, 100k miles, oil never changed I think… every now and again only when down shifting I think around 3-2nd gear it kind of does it sharply… sort of a shunt if u get me… only does it now and again. Would a gearbox service sort this or is it more like a solenoid etc? Would greatly appreciate your input and u seem very well educated on this gearboxes!
GREAT Video!!! Do you know what causes the "Service Shifter" message? Mine was on for years without any problems but one day my 2017 Jeep Grand Cherokee just stopped moving. The PRNDL on the dash flashes and the Jeep just stays in neutral even though the shifter and dash says Drive? Had a new Valve Body installed and the Jeep ran for about 40 miles but really HARD downshifting, poor mileage and higher tranny temp than usual... 220/230 as high as 240 within 10 minutes on highway? Then the Jeep went into LIMP mode. Took it home and now 2 days later check engine light gone and it's driving fine??? WTF? Last thing, do you recommend a TCM reset??? Thanks!
Hello, After I changed the fluid in 2018 q7, the car randomly does not want to go to park and give the P07BE00 Parking switch A/B correlation code. Went to the dealer they said the fluid might not be at the correct level and want 1k to redo the fluid. Any suggestions would greatly appreciated. The car run at 90C after 30-40 min which is in the normal temperature range....
hi mate, i've found a lower leak (not near the input shaft) on my ZF8 only 27k miles on the clock. my garage will be changing the pan over but he also said it's extremely unusual for the ZF to leak at that mileage. Does it sound any more sinister than just a fan replacement and re seal ?
Hi Gareth, thanks for the video from the UK, its been about 45 years since I stripped an engine and gearbox. ZF transmission is unbelievable in my Alfa Stelvio. Only slight issue is in auto it sometimes won't shift up in the normal rev range from a standing start until I paddle/Stick Any ideas?
Thanks for the video. I have one in my Ram 1500. It’s having issues when the fluid temp is below 90 degrees. It has little milli second slipping almost timed, it’s weird not the typical slip of transmissions of the past. When it warms up the little throttle jump/transmission slip goes away, but the shift is not as aggressive as it was prior to this. I was going to start with a filter and fluid change before taking to dealer. How many quarts of fluid does it “usually” take? Thanks!
What do you think about using the oem ZF 8HP90 for drag racing? Mine in my Hellcat was ruined by bad tuning I believe and I need to replace it. I’m either gonna go with a new oem or have one “built” by d&b in Memphis.
Got my transmission fluid changed. BMW. Now when down shifting (to a point of 21 km/hr), it feels a slight jerk. Sometimes harder, sometimes barely perceptible. It could be low fluid?
I'm at 293k miles 2015 chrysler should I change my fluid?? I know it's super high mileage prolly the highest in the country.. shifts smoothly no issues
i know you guys do mostly bmw's and the sort, But I think it would be interesting if you guys have any knowledge on the Ferrari/Maserati F1 transmission system. I know a lot of people would be interested in an expert doing a clear video going over it.
Thank you for the knowledge, I'm using F30 ActiveHybrid 3 using GA8P70H there is an electric oil pump which the diag Code showing up I guess it's broken. I try to find the part but I couldn't find it. Any suggestion ?
Great video. I do have issue with my ZF8 and any advise would be much appreciated. When car is cold the gearbox is smooth but after 10-20min or when car reaches full temp the gearbox stating to play around little bit. Gears are changing not smoothly and under moderate acceleration shuddering can be felt between 1500rpm and 2000rpm. Shuddering is not strong but car is not accelerating smoothly and wonder if fluid and filter change is required? Anyone had issue like this? My car is F15 M50D
@@lenorolkos18 I’ve done ATF and filter change myself but this didn’t resolve issue btw. Most likely is tires. Quattro and Xdrive are very sensitive and allow only 1% tire difference between front and back.

Garth touched on this in the video and mentioned the connector as a possible fault if there was a leak in its seal. You don't give any specifics however such as miles on the car etc...
Hey there. Coming in late, but I have a question with a Charger 8HP. Could oil getting into the electric connector cause an issue like a gear change hanging? Meaning it feels like it goes into neutral for a second before going into the next gear. I've been coming across that lately and Dodge doesn't seem to be fixing it. Thanks
Thank you for this video. I watched the other vido on changing the transmission pan/filter and oil, purchased from FCP for my 2012 BMW 535i xDrive.

The pan I purchased to service my ZF8HP on a 2017 BMW X5 has the latest revision with the white transluscent filter casing. The pan is co-branded Hengst and ZF.
Great transmissio; 270k km still with the factory oil, no issues 👍
Nice.. What type of car? Might want to get a fluid / filter change done soon.
Getting my Q5 TDI done now at 180k.. Was factory. Curious to learn the state of it. Audi saying these were good for "life" but cheaper to service than full replace.
What could cause rough shifting? I notice it most in the middle most used gears. From 4 > 5 > 6 and back. More noticeable with cold engine / transmission.
thumbs up - love these videos, keep pumping them out FCP!
Have it in my ram and it's amazing. German engineering.
BRO !!!!!! CAN YOU EXPLAIN HOW TO REMOVE MECHATRONIC VALVE SLEEVE FROM 2011 F10 N55..... WHAT IS LOCKING THE PIECE IN??????????????????????????
Great video! Is there a datasheet with the recommended service interval for every fluid, spark plugs etc in one place? If not could you compile one? :) I have a 435i xD with 30k miles and I would love to have pointers on what is next on the maintenance. Thanks!
See the car manual.
Thank you for the information!
Great video - thanks... Maybe you can guide me here.. Over the past weeks I have discovered problems with the transmission... Worse when the temperature is below freezing... gets better when the engine is hot and even better shen the weather temp gets higher... Difficult to set into Reverse - have to put it into Drive mode first and then Reverse... When I start drive the rpm goes higher before shifting, and 40 miles an hour with 3000 rpm, does not get the transmission to shift... It's like only the first 3 or 4 gears are being used... Manual gear is not possible...
One day is totally crazy - the next day it runs without any issues...
Yesterday the oil level was checked and was ok - the oil was dark but not black.. not clear... The car has just turned 100 K miles..
I drove the car to a workshop specializing in automatic transmissions, and they said worst case scenario is a new transmission.... My car is a BMW F31 from 2017 - well seems like a huge expense on a relatively new car..
Any comments/ideas :-) and happy new year to all...
To replace 7 or 11 litters by pumping out all qty?
Awesome video and technical insight ✅👌
Legendary Germany Powered. ZF series automatic tranmissions!
very thank you for this video
Hey there, a shop claims that they have to drop the entire mechatronic to change that wire sleeve. Is that true? Is it easy to change it? Seems like mine is leaking
Great Video. Thanks for sharing
Evening guys, I have the 8hp 45 in my 2011 5 series yBMW. I’m suffering quite badly with a very sluggish gear box with hanging onto gears, getting nudges when down shifting esp from 2nd to 1st. I carried out an oil service with new pan and ZF lifeguard 8 oil approx 2 years ago and have since drained and refilled the box twice to try and flush with fresh fluid. The car feels really lazy and is weak to take up torque. It’s done 170k miles now. Any ideas? Thanks
Can you make a video about the transfer-case ? Btw i have the transmission in my bmw , and it can jerk between first and second gear especially when the gearbox is cold. The car has 100K miles and as far as i know has not had a transmission service . Is a transmission service advisable at this point ?
ps
Love the videos, keep up the good work
I always thought it was weird how the transmission kind of jerks on 1st & 2nd as well. 58k on mine
This could possibly just be that you’re low on transmission fluid.... I got liqui moly in mine after my trans was serviced. Bottle is about $7 from FCP
100k miles = 160000km. ZF recommend the oil and filter change every 80-120k km. So here it's your answer: do the service! And use ONLY the HP8 oil, not any dexron stuff.
@@AlessandroGenTLe I was planning on using liqui moly atf1800 , as it for the 8hp
@@thebmwfan Yes, that one is compatible as it has the 9.55550-AV5 certification. To be added to these: Petronas Tutela AS8 / ZF LifeGuard Fluid 8 (code: S671.090.312) / Vaico ATF 8HP V60-0264 or RAVENOL ATF 8HP Fluid
They are green, not red.
Hi, really appreciate the video, is there a manual process of checking the oil temperature? Also how much oil does a 520d 8 speed tran takes.
If BMW had just replaced the oil and filter in my F30`s ZF 8 Speed Auto transmission , they wouldnt have had to pay almost 70% of the value of the car for replacing the transmission that failed . Annoying but gratefull that it was still under its motorplan / Warranty .
what about the 8HP70? have you done any work on those?
Yes very educational..
I used your video from the X5 8HP service to do the fluid and filter change on my 228i xDrive - messy without a lift but it was a surprisingly straightforward job. Your complete kit was exactly what I needed - I just wish the ZF Lifeguard fluid wasn't so costly. Have you & others had good luck with the Liqui Moly Top Tech 1800 fluid instead?
No - use chevron fully synthetic multi-vehicle ATF which meets / exceeds the spec for the OEM fluid at 1/4 the price !
@@patrickdunn6701 it doesnt. multi vehicle atf meets requirements for more common automatic transmissions like ford’s mercon lv. do not put that in ur zf8. lifeguard 8 is not like normal atf and has different viscocity at different temp points
Will Sasso does transmissions !?
Excellent!
Once we saw him in Super Troopers 2 we knew we had to bring him in for DIY work.
Here is the thing , No mechanic have found my ZF tranny issues ..
* It makes whining noise when pass 2,500 rpms "sound like a supercharger belt"
*Some times loss torque just when change from 1st to 2d gear no always
* Highway or city speed no issues
* Fluid and pan was replaced at 100k miles
* Problem starts with 115k miles
*Filled with original Mopar fluid
All mechanic says never heard that issue
newer (2021+ MY i believe) now have a metal pan with a separate filter. i have tried it yet, but the shape is the same, so you should be able to snag one of those pans and save the $200+ for a pan/filter
Now only if the ATC35L Transfer case was just as robust.
I do agree though the 8HP is amazing, and simple to take care of.
What’s wrong with the T-case?
@@michaelnikprelaj6679 it's mostly with the diesels, but they are pretty weak with the splines on the rear output drive flange shearing, and the clutches wearing.
Would to see fcp do a transmission swap video for the 328i
Great content. Do you recommend doing the mechatronic & Can bus seals at the same time?
Hi, do you recommend replacing the pan with an aluminum one? It seems that the updated pan is aluminum, what are the benefits of replacing it to a more expensive aluminum pan?
Thanks for the video! I have noticed if I start my car F30 from cold, and set off within 10-15 seconds, the first up shift from 1-2 is pretty delayed and sounds like it’s slipping. If I idle for 30 seconds it does not do this. Otherwise the transmission operates normal. What do you think is the problem?
It’s completely normal. Mine does it too and I got my valve body completely overhauled + flushed with 11l of new oil. I heard this from a lot of people and it seems to be normal
@@iPlayzz I don’t think it’s normal but I think he should get a fluid change just incase it hasn’t had one.
I have the same situation on 2017 X5. The service adviser at BMW said it would be to hold gears 1-2 a little longer to warm up the cats a little faster to reduce emissions caused on cold start.
A question to Gareth and the Community:
I had an appointment at a ZF service point to flush and change the transmission oil of my ZF 8HP45 after 85k km. My F20 is changing gears like a brand new car since then. However, when the transmission gets hot, it starts to smell quite badly via the air vents. This issues occured right after the oil change. After two weeks it is not gone yet, althoug it has improved slightly. The service staff double-checked the transmission. No leakages were found and no oil was outside the gear box. They told me, it is quite common that the F20 or F10 series from BMW tends to smell due to the fresh oil. It should stop smelling after a while.
Have you experienced something similar so far?
Thanks.
Yes , its OK
You are the best!!!
Nice shirt
Mine just broke at 80k miles… 2015 bmw 328i. Im getting a used one installed tmrw
Thank you for info good man
Any time!
Great video!!! I have Audi Q7 4M model, from 2015-2021. It has ZF 8 speed automatic transmission. I have 170 thousand kilometers on it. I don’t know if a previous owners done the transmission fluid change. Do you recommend me doing this at this stage? Also, which transmission fluid you recommend, original from Audi dealer or ZF one? Thanks for your reply 😉👍
I'm guessing the trans service would be the same for 2016 535i Auto ZF8?
i bought Audi A8 2016 v6 supercharger has 128,000km do you recommended to change transmission oil I don’t know if it has been changed before or not
Yes!
Wish all videos were as well explained! I have a 2016 Audi Q7, 100k miles, oil never changed I think… every now and again only when down shifting I think around 3-2nd gear it kind of does it sharply… sort of a shunt if u get me… only does it now and again. Would a gearbox service sort this or is it more like a solenoid etc? Would greatly appreciate your input and u seem very well educated on this gearboxes!
GREAT Video!!! Do you know what causes the "Service Shifter" message? Mine was on for years without any problems but one day my 2017 Jeep Grand Cherokee just stopped moving. The PRNDL on the dash flashes and the Jeep just stays in neutral even though the shifter and dash says Drive? Had a new Valve Body installed and the Jeep ran for about 40 miles but really HARD downshifting, poor mileage and higher tranny temp than usual... 220/230 as high as 240 within 10 minutes on highway? Then the Jeep went into LIMP mode. Took it home and now 2 days later check engine light gone and it's driving fine??? WTF? Last thing, do you recommend a TCM reset??? Thanks!
Hello, After I changed the fluid in 2018 q7, the car randomly does not want to go to park and give the P07BE00 Parking switch A/B correlation code. Went to the dealer they said the fluid might not be at the correct level and want 1k to redo the fluid. Any suggestions would greatly appreciated. The car run at 90C after 30-40 min which is in the normal temperature range....
hi mate, i've found a lower leak (not near the input shaft) on my ZF8 only 27k miles on the clock. my garage will be changing the pan over but he also said it's extremely unusual for the ZF to leak at that mileage. Does it sound any more sinister than just a fan replacement and re seal ?
How many quarts of ZF oil should i put in the oil pan when i do an oil change on this automatic transmission ??? Thanks
Did this today on a 2014 Durango 3.6 awd. I only got about 4 qt back in. Seems like it should be more.
Hi Gareth, thanks for the video from the UK, its been about 45 years since I stripped an engine and gearbox. ZF transmission is unbelievable in my Alfa Stelvio. Only slight issue is in auto it sometimes won't shift up in the normal rev range from a standing start until I paddle/Stick Any ideas?
Hi,can I ask you an advice?on a 100 miles no maintenance gearbox should I flush process or only ordinare oil change?Thanks!!!!
Thanks for the video. I have one in my Ram 1500. It’s having issues when the fluid temp is below 90 degrees. It has little milli second slipping almost timed, it’s weird not the typical slip of transmissions of the past. When it warms up the little throttle jump/transmission slip goes away, but the shift is not as aggressive as it was prior to this. I was going to start with a filter and fluid change before taking to dealer. How many quarts of fluid does it “usually” take? Thanks!
Expect 8qt of oil for your ZF8HP
What do you think about using the oem ZF 8HP90 for drag racing? Mine in my Hellcat was ruined by bad tuning I believe and I need to replace it. I’m either gonna go with a new oem or have one “built” by d&b in Memphis.
Pure transmissions make awesome zf builds. Check them out.
get that heat shield cleared from drive shaft?
Got my transmission fluid changed. BMW.
Now when down shifting (to a point of 21 km/hr), it feels a slight jerk. Sometimes harder, sometimes barely perceptible.
It could be low fluid?
I'm at 293k miles 2015 chrysler should I change my fluid?? I know it's super high mileage prolly the highest in the country.. shifts smoothly no issues
i know you guys do mostly bmw's and the sort, But I think it would be interesting if you guys have any knowledge on the Ferrari/Maserati F1 transmission system. I know a lot of people would be interested in an expert doing a clear video going over it.
3:43 recommends zf brand. 4:23 “really don’t want to use the zf branded”?🤔 I’m confused..
He said "really only wanna use the ZF pan"
Thank you for the knowledge,
I'm using F30 ActiveHybrid 3 using GA8P70H there is an electric oil pump
which the diag Code showing up I guess it's broken. I try to find the part but I couldn't find it.
Any suggestion ?
Great video. I do have issue with my ZF8 and any advise would be much appreciated. When car is cold the gearbox is smooth but after 10-20min or when car reaches full temp the gearbox stating to play around little bit. Gears are changing not smoothly and under moderate acceleration shuddering can be felt between 1500rpm and 2000rpm. Shuddering is not strong but car is not accelerating smoothly and wonder if fluid and filter change is required? Anyone had issue like this? My car is F15 M50D
I got exact same issue, don't know the solution yet
@@lenorolkos18 is you car 4x4 or xdrive etc? did you recently change tires?
@@lenorolkos18 I’ve done ATF and filter change myself but this didn’t resolve issue btw. Most likely is tires. Quattro and Xdrive are very sensitive and allow only 1% tire difference between front and back. Haven’t changed mine yet but my started “shaking” when I’ve changed front tires and kept rear ones as they were good. Learned now that when changing tires on xdrive all 4 needs changing no matter if let’s say rear ones are still good. It’s stupidly stupid invention that unfortunately requires us to spend unnecessarily extra $$$ otherwise if tires are not changed we risking transfer case problems or failure
2013 F30, 220k km, no any problem with trans. Wanna another 10 years and 200k km, change pan/fluid now or not? what's the worst situation if change? any suggestions?
Hi I have a BMW F32 435 AT 8 speed, Quick question when you put the car on sports plus and on manual mode, and you floor the throttle from gear 1, does your car go into overrev or does it automatically shift up to second gear?
Does a 19 ram rebel have a transmission thermostat? please add link for upgrade.
2013 my14 335i m sport the drive gear on the on the dash the sqaure around it was flashing and the d gear on the shifterbwas flashing mate is saying it might need oil flush and pan hopefully its just the that but id like to hear ur opinion sir
My f30 328i xdrive has 76k miles should I consider servicing it
Question for you is it a bad idea to get the ZF gearbox on the BMW G30 530d xdrive flashed. I was considering the Alpina flash for mine before I get the engine map done. Any help would be greatly appreciated. Thanks.
What about when swapping a 8 speed transmission with a used one. Is there anyway around the coding?
Hi if a f series auto isn't going into drive ...where would you recommend starting...? In terms of eliminating fault...ool change and filter first
Garth touched on this in the video and mentioned the connector as a possible fault if there was a leak in its seal. You don't give any specifics however such as miles on the car etc...
Hey there. Coming in late, but I have a question with a Charger 8HP. Could oil getting into the electric connector cause an issue like a gear change hanging? Meaning it feels like it goes into neutral for a second before going into the next gear. I've been coming across that lately and Dodge doesn't seem to be fixing it. Thanks
Thank you for this video. I watched the other vido on changing the transmission pan/filter and oil, purchased from FCP for my 2012 BMW 535i xDrive. Question: My car is still downshifting hard and bucking a bit in gear under load. Do you think I could replace the mechatronics unit on this my car to correct? Other than transmission, 130 miles and running like a top. Appreciate your input!
What about the start stop system pump? Maintanance
