Hi guys,My bro is having the infamous 'lurch' (car jumps before it comes to a standstill) with his x5. I have done a tonne of research (as I was the one who 'racun' him to buy a BMW ) and it seems to be quite a common problem with BMW's with ZF gearbox. The gearbox in his x5 is a 6hp26.Anyhow the following has already been done:-1)Change ATF2)Reset the gearbox3)Drive for few days, still the same4)Update the gearbox software. The newer software was suppose to solve the problem, but still the same :sleep:So finally my mechanic (actually I went to 2 different mechanics to get different opinions) said that its the solenoid in the valve body. The cost of replacing it will be around RM2.5k. However he can't guarantee that it will solve the problem, and he might need to send the valve body for servicing which will cost another RM3k. I found another gearbox specialist in Motortrader (suppose to be ZF authorised reseller) called Hi-Tech Recond Auto Parts which sells recond valve body for around RM4k. Does anyone here have any experience with them? I have had some bad experience with recond parts and am slightly concerned.
