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.

It does not matter whether the GB light is ON or not. The error is recorded and store in the GB module.
You need to clear the alarm and run the engine again. If the GB got problem, the alarm will be generated again.
ECU alarm reset does not clear the GB alarm. Different modules lar.

Bishop, many possible factors go with the cheapest ones first
1. the famous jerk is the atf oil not sufficient, get the oil level check, usuall suspect after gearbox change, first time never right.
2. could be the ecu..some times they are faulty..
3.or get the replaced gearbox changed again..
4. sure the gearbox is the right model for your car, certain models dun match, ayam-itik talk..
alternater is just luck it died, nothing link to gearboxes..
cheers..

your mechanic would have filled them up when the gearbox was done, so a small top up would be 1 to 1.5 liters...
do a small surge test to see if the oil is enough.. do a 50 km/h fast braking, car stops to standstill then, accelerate immediately up. if the car moves, then ok, if hesitates, then less oil...

Gave the option to M1 to either rebuild or replace gearbox when i left my car with them in December. They were initially adamant on replacing with a reconditioned unit while i preferred to rebuild if possible, so i left them the option to choose based on what they diagnose after the gearbox came down.
Collected my car yesterday and kinda remember getting a call earlier that morning (through my medicated state of mind) to say the gearbox was reconditioned.
Total repair bill came to about RM7,800 for the total, out of which RM6500 was for reconditioning of gearbox which included changing the clutch, oil seals, machining the torque converter, and some other things which i can't remember at the moment.
The balance was for workmanship, ATF oil change, tax, etc... overall am ok with the price as long as the gearbox doesn't fail on me in the near future.

For RM5000 to rebuilt i think is exclude rebuilt touque converter. it seem outside there got alot of price. i done my rebulit ar RM8000 but with 2 years warranty.
That happened to me twice, and i had to change the valvebody and clutch on the 2 different occasions. Cost me around RM2.5 k for each. But if i remember correctly the time i changed the clutch they changed the transmission fluid aswell. And the shop told me must use the BMW oil or the gearbox will kaput again. I sent to this guy in Kayu Ara @ Classics. Quite a reliable chap.
