Issues with tranny - SOLVED

[wacuna]

I'd like to share a experience I have with my tranny and how I fixed it. I have a 2008 X5 3.00si. The tranny was acting up and had no reverse. I used carly and I got the following codes:

507B PARKING GEAR SENSOR IMPLAUSIBLE
4F82 RATIO MONITORING CLUTCH E
4F84 RATIO MONITORING CLUTCH D

After I opened the Mechatronic and found out that the bridge seal (rubber block) between the Mechatronic (valve body) and the transmission housing, had a crack.
I replaced the rubber block and problem solved.
Part number 0501 215 783 01 (ZF part number)

If you have any of those codes or even just one, it's very likely is the part number that is compromised.
I hope this help X5 owners here.
