Re: Gearbox Solenoid Change - Jerking Problem Solved - E90
Unfortunately, even after replacing the 7 pcs solenoids it does not fix this problem.
According to Doc Rod, fiction plate worn off. Overhaul can fix this problem.
Hope this help..

Re: Gearbox Solenoid Change - Jerking Problem Solved - E90
If decided to do a transmission overhaul, may consider WCA which many of fellow bros went over to. I was quoted RM7k downtime est 1 week.. parts replace take abt 2-3 days, the rest are testing, so could be shorter. below sgd3000... Save at least sgd1k plus..
I am still thinking whether to do it or just leave with it..

Aaron_BMW;949010 said:Dear all,
This post is especially for those who have gear box jerking problem and are at a lost at what to do.
For those whom are deciding to buy a pre-owned BMW and yet you have hear of scary tales of the expensive gear box repair, this post is to assure you that having to maintain a BMW is not so bad and I do recommend you to go ahead with the purchase of a BMW and join our big family.
Problem:
My BMW jerked forward when coming to a complete stop.
It’s not a very bad jerk but I do not enjoy it.
This is also known as common problem for E90 and I would deem this under fair wear and tear of the gear box solenoid.
Solution:
Simply replace the solenoid and with a reprogramming of the gear box.
My gear box works perfectly fine immediately after replacing the solenoids.
Function of solenoids:
Simply for the gear change from 1 to 6 and the 7th solenoid is for reverse.
Value for money recommendation:
Our BMW has a 40,000 KM gear oil change interval together with the oil pan which is actually the in-build gear oil filter. So I recommend to do the solenoid replacement together with the gear oil change as part of the servicing.
Items needed:
Please see pics below.
Oil pan with build in oil filter
Gear oil * 7 bottles
Replacement solenoid to solve the jerking problem.
Conclusion:
Our gear box is still great and should last us for a long time. The solenoid in the gear box might not last as long but this does not mean our gear box is damaged unless proven otherwise that the gear box is really damaged and needs to overhaul. I hope this sharing helps to assure a lot of our bros and sis here for our BMW.
Please feel free to PM me if u need to ask anything as this is easier for me to reply.

Re: Gearbox Solenoid Change - Jerking Problem Solved - E90
Are these pre GST or GST inclusive prices? Either way seems to be cheaper than ES.
I was quoted $550 for solenoids, and gear oil was $22/L. Either way your stockist sounds cheaper. Which stockist is this? Looks like I'll go there instead of ES in future.
