[QUOTE="moneytree, post: 12517, member: 12549"] Does anyone know a good workshop that can repair BMW auto transmissions that has some issues with missing gears (not complete failure)? This is for X5 4.4i 2002.I believe it is a ZF 5HP24.Would any otherwise good and recommended workshop be able to handle this task? This is the report:After driving for a while, such as half hour, the transmission does not shift gears properly anymore and misses to upshift at proper RPM. Usual operation at startup is quite good and not any sign or jerkyness or error message.The first 10 to 15 minutes the transmission works better, then it becomes worse as the car warms up.Shifting is also still carried out smooth, however the shifting point is much too high, I need to rev the engine to about 3 to 4K before shifing occurs.
