I'm definitely gonna try a fluid change i'm just scared by doing so will again make the jerkiness worst since It did get a bit better after getting it back from the dealer but I definitely still notice it's there. Do you know if I will have to reprogram after changing transmission fluid?
Thanks!
Hello,
I have gone through so many articles trying to figure out a solution to the jerk of my car.
History:
My car jerks like I got hit from behind when it comes to a stop and it jerks when the MPH hits 5mph which is im guessing when the car goes to first gear. I had to reprogrammed at a local BMW shop and the jerk was not as prominent but it was still there. I took it to another shop and they reprogrammed it again and it seemed to have made the jerkiness worst. I then just got so tired of it that I took it to the BMW dealer. They have checked it out and reset adaptations etc and it definitely made it better and once again it is still there and they said the only way of repairing this issue is by replacing the transmission which is around 10k. It is not worth spending that much. After I picked it up from the dealer, it jerks only when the car starts to run normal temperature whether it being AC on or OFF. It once again has a minimal jerk but still does it when I slow down and MPH hits 5mph. After I picked it up from the dealer it most of the time jerks but minimally and sometimes it doesn't jerk at all.
I am a bit confused on what really is the issue and hoping someone in these forums has come up with a solution or if someone is having the same issue. I have gone through so many articles and they are all dated around 2005 - 2013 the latest. I am just wondering if anyone has a solution now that it is 2016
Only thing I have not tried is changing the transmission oil.
Looking for some assistance.

This is common with the ZF6HP transmissions.
Resetting the tranny adaptations or reprogramming the tranny can reduce the issue TEMPORARILY.
Changing the fluid will not fix the issue. Replacing the transmission is not necessary.
The problem is that the shift solenoids on the mechatronic (valvebody) inside the tranny get lazy as they age.
This leads to the jolt you get when the vehicle slows to a stop and the tranny shifts to 1st.
You can replicate this jolt by entering manual mode and shifting from 1st to 2nd and back while at a stop.
You'll feel the same jolt then too.
Replace the solenoids and this will be fixed. If you don't, the tranny will eventually begin to slip out of gear in between shifts and throw a gear ratio error.
The solenoids can be bought from thectsc.com for $400
You will also need some ZF Auto tranny fluid.
Might as well replace the integrated pan/filter too.
If you are handy, replacing the solenoids is an easy DIY. The hardest part is raising the car and making sure it is level, so you can properly pump the new fluid back in when you are done. Still very easy.
Whatever you do, DO NOT let a shop install a new transmission. That is overkill. Don't get raped on solenoid prices either. Buy them online and send them to your shop or have your shop price match if they are doing the repair.
Your transmission will be better than new when you get done. If you have questions, let me know.

My car has the same exact problem and changing the fluid or pan didn't help. The other day I had a problem were my car got stuck in 3rd gear from doing a 2 hour drive. Do you think the 2-1 slam and the car getting stuck in a gear is caused from the same problem? And I've heard about the getting my solenoids changed too from asking around. Will look into that

Hi Did you ever figure this issue ou? I know a very old post however, I have the same issue. After spending thousands on replacement of brake sensors and trans filter, I am still having same issue.please help
If you have the ZF transmission in your E60 then you also have internal seals that include the bridge seal. These need replacing every 60,000 miles or so along with the fluid and pan. When the seals harden, shrink, or break, they mess with the shifting pressures and can cause your jerking. As for the “reprogramming” you mention in your other post, I bet they just reset the adaptations. If that’s all they did then they are only supposed to do that after a full transmission service.
If you haven’t changed the seals, fluid, and filter, you need to.
