ZF 6HP19 Mechatronics Sleeves & Solenoid Replacement - E90 BMW 335i DIY

The ZF 6HP19 transmission has it's common problems just like any other unit, the main one being that the mechatronics sleeves tend to crack and need to be replaced at some point. When this happens, you'll likely get harsh downshifts from 2nd to 1st. You could also get gear monitoring codes such as:

4F8D: EGS: Ratio Monitoring, Gearshift 5-4

Sometimes changing the sleeves can fix this error, other times the solenoids need to be changed. In this video I will do both.

WARNING: This transmission takes special fluid. Do not use the red ATF. The proper fluid is gold. Only use the ZF Lifeguard 6 or the Febi 34608!

A good advice to all would be DIY enthusiasts. It is better to own two cars so that you can work on one while the other car is standing by ready to go to harbor freight to buy more tools or parts.

I did my seals without the solenoids in a 2009 E87 with a ZF 6HP21 (in Australia) @ 230Ks young !! I did not reset the adaptations and just drove it. Although the issues caused by the leaking seals had gone.... (slight flaring and not changing down smoothly), the software had "learnt" some poor "new" change patterns while it was flaring and poor changes - all the research I did all said that the software is "programmable" via driving style BUT it also said that it's a good idea to do the adaptations when you buy a used vehicle so it will "learn" your driving/shifting style. I found that after a few days of driving the software learnt my style and everything smoothed out anyway. I freaking love my BMW's.

So cool to see the E46 in the background. IMHO the best looking 3 series ever. Keep it up Jason!

You will benefit from shifting from park to neutral to reverse to neutral then adaptive shift from 1st tot 2nd and repeat that process twice with a 3 second delay between each shift. This is done with the oil temp at 40 deg celcius. This ensures that the transmission will have the exact correct amount of fluid as per ZF fluid fill instructions. After you reset the adaptations the vehicle will relearn the best shift pressures over approximately 60 klm of normal stop start traffic driving. Great video.

Dude! You just saved my car! God Bless! BTW, YOU MUST PUT IN 9 to 10 LITERS IN! Look at the BMW/ZF service manual for this. 6 Liters is NOT ENOUGH!

Slush box work seemed intimidating but your video made it less so. Thanks.

I bought my E46 6 years ago at 131k and your videos are the reason why It runs better now than it did when I bought it! 210k and running strong! I'm here now just to learn new tricks from a great teacher!

TOO ALL OF YOU WATCHING THIS. this is the rwd model without xdrive. if you have xdrive some more stuff has to come off to get the mechtronic sleeve out and the new one in. exhaust has to come off, as well as heat shield, and transfer case mounting bracket, as well as the front wheels driveshaft (only need to remove the end near the tc. replace those 4 bolts though as they are stretch tty bolts. since the tc bracket has to come off, might as well change that tc fluid too (takes bmw -df spec fluid which is about 40 usd a quart)

Wow, you're a very talented instructor, and very easy to listen to. Can't believe anyone could possibly give this video a thumbs down.

[steeldesk]

Awesome video, thank you for your contributions to the car enthusiastic mechanics out there.

[chuggalueroifan]

Glad you’re back I missed the realism of your videos

[bonganiblacksmith]

Very helpful and informative video 😃. I have an E90 whose transmission needs servicing. I appreciate this video. I live in an area wherein mechanics who don't really know what they're doing are willing and eager to experiment with your car.

I took my car to replace my bad turbocharger some months ago, that is the day I came back and decided to do it myself - Videos like these are really helpful. Thanks 😊

Good vid, going to be a lot of people having to do this job in the near future as more of these cars get to the bmw diy community.

I wish I had an English version of INPA. Nice job 👍
