Re: Gearbox Solenoid Change - Jerking Problem Solved - E90
Hi I'm a Beemer newbie, just bought a 2006 E90 with 130k on the clock very pleased with the drive. Did notice the slight jerk when almost coming to a halt, thought it was my poor braking technique LOL. Have just changed the ATF and will continue to monitor. If the problem only occurs when gear 2 downshift to gear 1 why change all the solenoids why not just change the offending unit? Thanks for any advice.

Thanks Zincman, actually the previous owner has been servicing with R2D for the previous 30,000 km (I have the service records). Wonder that they did not pick this up or may be its my bad luck and its a recent development. Like a previous bro mentioned, when I tested the car I did not notice anything amiss, sent for AA inspection also nothing mentioned.

Re: Gearbox Solenoid Change - Jerking Problem Solved - E90
That time, my car also have this jerking problem , went to BXX to do other rectifications like replacing of suspensions and settle oil leak and they help me to reset the error for me and ask me try it out.To be frank, it was totally fine no jerking but after 3 weeks, the jerking comes back again.No choice bite the bullet and replace the solenoids.So far so good and i changed ATF regularly.If not you can call Ellipse Auto Transmission .Specialise in gearbox for 2nd opinion.

I note that R2D used Millers ATF with Lubeguard at the 110k service. At my ws they flushed and used Luquimoly TopTec1800 which conforms to BMW's ATF spec for my transmission, touchwood the hardshifting from 2 to 1 seems to have much improved, fingers crossed ...

Re: Gearbox Solenoid Change - Jerking Problem Solved - E90
I am quite sure u have the same problem.
Please do a gear box re calibrate to try solve this problem.
If u cannot solve it, then u have to follow my thread to solve it.
To answer ur question, all the solenoids have similar life span after being used together in ur gear box, should one of them break down, the rest would almost break down soon.
U will incur double the down time and labour cost should u choose to only change one solenoid and by the way, the solenoids don't sell in separate parts too.

Re: Gearbox Solenoid Change - Jerking Problem Solved - E90
Thanks Aaron, I do notice that for many transmission problems encountered in German cars often the first "solution" offered is software reprogramming cf the VW DSG saga. But if root cause is a mechanical hardware failure isn't this a rather pointless fix? Unless you tell me that it is common for the software program to drift over time and therefore need regular reprogramming.

Re: Gearbox Solenoid Change - Jerking Problem Solved - E90
Yes, the cheapest way and highest possible method to solve the problem instantly would be to re calibrate first.
Should this fail, then u spend $ to change the hard wares.
There are many cases where the car works fine for a long duration after re calibration and this pro long the usage and saves the $$$ till further damages.

Tks they were looking after this ride for the last 30k since it emerged from PM care at 95k. After seeing the black death photos I got nightmare thinking of what condition my engine will be in under PM extended oil change protocol

Just get workshop to open up engine cover (usually for engine cover gasket change), or bottom oil pan (change oil sensor).
Either way, you can then see for yourself how sludge up your engine is.
