Hi
well this weekend I will be repairing my 3rd 525i transmission for a friend.

Previously I removed the valve body and sent it to china to be serviced and fitted with new solenoids.

This weekend I will do it all myself

The reason I am rebuilding the valve body is the same as my previous repairs.

Hard changing, slipping into safe mode and not always selecting reverse.

I will let you know how it went

I also have to remove the transmission on my 525i to change the leaking rear main seal

A busy weekend

 

Keep us updated, I just installed my valve body that was repaired and all solenoids changed but I'm still having issues. I keep getting this code "4f8a gear ratio monitoring, 4-5 gearshift "
