[QUOTE="Bishop, post: 23371, member: 600"] Hi guys,driving E39 523 '99 Double VANOS. My torque converter died on me recently, so my mechanic recommended might as well change the whole gearbox the car already has 230k++ mileage. So he installed rebuilt one. Seems ok at first but after a while(same day) there is a jerk(clunk?) and the Automatic Transmission light came on, then felt that the gear seems to be slipping(like when press half clutch on a manual car). Was worried so pulled the car over and shut down. But after restart everything was ok. After a while again a jerk the the gear was completely free. Again everything fine after restart. Took the car back top the mechanic and he said he forget to reset the ECU. After reseting the same problem occurred twice. Then my Alternator failed. Got a new one to replace. He said problem might be cause by the old faulty alternator cause not enough power to the gearbox(?). Yesterday the Automatic Transmission light appeared again(gear with "!") When the light appears all the gear indication turns off (P/R/N/D...) After restart everything seems fine. What is the problem? Faulty gearbox? Gearbox mounting? Wiring? Electrical?Please help.
