Welcome to the club ..

Please introduce yourself in the new member section .. which is a must for the new members ..

your issue is wtih the gearbox itself .. so either you have the wrong gearbox fitted to your car ( for example : you have V8 4.4L engine and they replaced your gear with V8 4.0L engine ) or you have a faulty valve body . no one will be able to give you the right answer , so the best option for you is to take it to a BMW Specialist ..

good luck

You have to re-adapt the new valve(gearbox) body to your car !
This is done with the aid of a GT1!
Providing that the gearbox is the correct spec for your car?

Bro as I said in the post you need to hook it up to GT1 only and not to a generic scanner !

You must also realise that there is a very unique way to change the gearbox oil and it can only be done through a GT1 at certain temperatures and then you adapt the valve body!

Have you checked your gearbox oil level and has it been changed with the aid of a GT1 ?

You can not just change the oil like a conventional gearbox ! the gears would just not shift ? This is what I have been taught !

Once again get it hooked up to a GT1 you will know a alot more regarding your issues!

i have the same simptoms, it all started with a "TRANS FAILSAFE PROG" in the dash -which abviously was a dead Battery thing.
battery was replaced but now the car will not shift unless it reaches to RPM 4 and then hard shift is happening.


Please keep me posted if any update.

Hello,

UPDATE,


mine turned out the the guy who was working in the car has mixed up the throttle body connectors "Black" with the ICV connector "white", which resulted a rough idle. -See the pic-.

for the gear shifting after RPM 4, it was the connectors as well where 2 connectors were not connected properly, disconnecting and reconnecting them resolved the issue.

now the beast is again on the streets :)

good luck with yours.
