Gary, I have an 09 550i with the 6hp28. 76k miles. I had the jolt/slip when kicking down into 4th gear when overtaking someone on the highway. It was going on for about 5k miles, but I did my best to limit the occurrences and it never threw a fault code. Finally in February it started slipping out of 5th and into 6th when in sport mode. That was not registering on the speedometer but I could feel it and tell by the RPMs. I got curious and went through gears 4, 5, and 6 individually in steptronic mode just to see if any were acting funny. Every time it was locked in 5th gear and I tried to give it moderate throttle, it would slip into 6th. It was a smooth slip, though. You’d only notice if you paid attention to the RPMs. I repeated the process a few times just to see if it was consistent and after the 4th time it went into limp home mode with a transmission malfunction on the idrive. I scanned it with ISTA+ Rheingold, and it had one code: 4F85 gear monitoring clutches B & E. It was the first time it had ever thrown a code for the gearbox (I am proficient in BMW coding and read the fault memory quite often). It wasn’t a hard code, either. 1st occurrence. I immediately stopped driving the car and I rebuilt the valve body with a Sonnax Zip Kit, new solenoids, all mechatronics seals & sleeves, and ZF Lifeguard 6. The car drives fine now. Better than fine actually. But it didn’t at first. I didn’t reset the adaptations immediately after. When i took it out for some spirited driving it still jolted and slipped. No fault codes thrown. I just did the adaptation procedure last night and it seems to have done the trick. My question is, do I need to rebuild the internals or can I get away with just doing the valve body rebuild?

@@GaryFerraro that’s what I was thinking, but I wanted to get an expert opinion. My valve body separator plate was completely delaminated on one side when I disassembled the unit.

The figure-eight shaped mechatronic seal was falling apart basically. The rubber gaskets completely separated from the hard plastic. I think I did the right thing by immediately parking the vehicle after the code was thrown. I only drove it down the street to my buddy’s shop where I rebuilt the valve body.

I did the exact same repair on my 2009 X5 3.0si (6hp19 trans) with the same clutch monitoring codes….I too did not reset adaption immediately, but once I did, the trans acted brand new….for about 2 years and 25k miles.…and here I am again. Throwing the same clutch-e codes with a 4-5 flare only when car (trans) heats up. I’m looking to replace the rear stator bushing now.

Make sure you get the correct plate code( example A053 or other side B053), Be careful when you lift the plate off where all the check balls are. When putting the 2 valvebody halves together, put a few bolts in and then install the TCM, that has the line up pins

That really depends on the trans, clutches should be changed and if the steels are ok, put them back if they are burnt you will have to replace. If your for instance working on a honda with 5 clutch packs, you will need to measure the thickness and in some cases you will not need to

You would literally look at rear mirror. It shifts into parking even if speed is up to something like 5 km/h - The moment you shift back into reverse or drive it will keep going back into parking and prevent you from driving. Car lifted in workshop and following was noticed as per them: - Particles of aluminum/metal shavings noted with in the oil pan (multiple small dots, nothing major). Oil brown and not bad. - They tried replacing the whole control unit (Except its black ECU) with two other complete used units and problem still persist. - They said the return hose of oil was too hot and recommended to replace heat exchanger + transmission thermostat + the whole gearbox with a used one. They suspected maybe the problem is from the heat or control box ECU damaged from heat or something else inside gearbox. Now I am confused what to do every workshop just recommend to replace the whole gearbox because in here it is cheaper than fixing. Computer test (ISTA-D) reported transmission oil fluid temperature of 67 °C only while in parking for over 10 minutes with engine at 102 °C and error code was coming so it didn't flag high temperature and the control unit ECU seems to be communicating fine.

Halo Gary I'm getting the same codes on my bmw too bt mine Dosent move at all I bought it like that idn if I replace the seal and oil would it fix it

Hello Gary, I must say you are a master at the ZF transmissions. I have been watching your videos for a long time and have found them to be very educational. My transmission has been acting up for the last few months now. I have a 2007 BMW 335i It has the ZFHP19 transmission. The issue is when when the car pull off from a stop the engine speed up and the transmission engages with a light thud. Also as the car come to a stop, it comes to a stop with a slight thud.feels like if some one taps you in the rear. When I took it ion to a garage. They replace the bridge seal and the four black rubber tubes, new lifeguard 6 fluid (complete flush} and new filter. Unfortunately, the problem is still there. Any ideas of what ‘tis might be? I have 95,000 Kms (about 60,000 miles on the car) I appreciate any advice you could offer. Kind regards!

Hi gary my dad has a 6hp26 and there was a rattling knocking sound from the transmission when the car is in neutral and it got louder when in drive we teardown the transmission and there is nothing disturbing exept the bushings are a little worn could this problem be from the torque converter.

Hi Gary, it has been a while since the last time I commented on your videos or asked you for valuable advice. it is very valuable to me because with it and by watching some of your videos I was able to rebuild my transmission on my 05 BMW 545i it's a ZF6HP26 6 speed automatic. well I took it out for a test run and it ran great!, gears shifted smooth and all for first 200 miles, and today I just got a message of transmission malfunction on the I drive and the car jerked from 3rd to 4th. I pulled code 4F85, all steels and frictions were replaced as well as all seals and bushings, valve body intermediate plate and dampers were also replaced, New solenoids were installed too. One thing I did not do since the valve body was from a different transmission was to program the control unit to my car's VIN #. Is this necessary to program the Mechatronics unit and the new solenoids The valve body was from a 05 BMW 545 as well but different VIN # and all solenoids were new I replaced the valve body and mechatronics unit because plastic was cracked. What programming procedure was needed in this case Gary

@AUTOdidact77

Yes, my car's (Jaguar S-Type, equipped with the same trans) workshop manual repeats the "filled for life" nonsense usual in the 2000s, but at least recommends a fluid change each 30.000 miles in case of "heavy use". ZF itself recommends changing the fluid at least every 100.000 km (around 60.000 miles). Besides that driving habits may have an even bigger influence on the lifetime of an auto trans - if you abuse it, regular fluid changes won't help a lot... I added this last sentence because you are a BMW driver (just kidding) 😎

Hi Gary can I conclude if my bushings are worn by looking diagnostic data? I mean gearbox pressure values. All are in range mostly negative values. Have codes 4F85, 4F82 and 4F8A. Any help would be appreciated. I have learn a lot watching your videos thx :)

@@GaryFerraro Hi Gary, I have a slightly better than basic scan tool by Autel, it shows no codes in the TCM. I do have a couple other tidbits... Vehicle did have trans fluid change about 18 months ago with Motorcraft SP, but the adaptation values were not reset (Didn't know they might need to be done). Vehicle has ~150k miles (mostly highway / I'm not a light foot & not a heavy foot driver). I notice the trans seems to unlock from OD just as the load lightens, then the RPMs wander by as much as 600 rpm. Sometimes it will re-engage quickly, sometimes not. An example would be going up a very very slight incline when the OD is locked, then cresting the incline to level, it unlocks from OD. It is very subtle, when it comes out, but I notice it because I'm paying attention. Again, could you speculate? Is there anything I could try before pulling the Trans & TC? I know the bridge seal is a common part to replace, as are the 4 smaller seals above the valvebody. Either of those repairs would be easy for me to accomplish. But going any further into the trans is above my paygrade... LOL!

It drives perfectly fine when cold but as it starts to warm up, the transmission faulty shows up on the idrive and the code is cleared once i restart the car.
