Hi, i needed help with my e60 523i having issues with reverse. The problem occur after a short or long drive it just won’t reverse/stall unless i turn off the engine and turn back on.

I did change the oil, new filter, all the seal and also solenoids. I scanned using obd it says monitoring clutch B-D

 

Do you know if the fluid was low before doing the service? What was the actual code? Do you have any slipping?

 

Did you top off the trans fluid with the engine RUNNING? If not, you are low on trans fluid.

 

I’m not really sure but when i did everything myself i guess the oil pretty much came out 4-5 litre.

The code 4f82 - Monitoring clutch B and i forget the other code but its monitoring clutch B-D.

 

I did. Two steps process, first without the engine running and second with the engine running. Now i’m clueless and lost hope 😩

 

I done a lot of research in which, i can’t really find the right answer. Im thinking of doing overhaul or maybe changing valve body separator plate with sonnex kit

 

You are short a couple liters. Did you follow the fill process. If you didn't I would follow it to get the correct amount of fluid in. You should of had to put almost 7 liters in the transmission. Once filled correctly then do a relearn on the transmission via INPA. Drive a couple hundred miles not flooring it and report back

 

Thank you, will do that and will update soon.
