E65 Transmission Fail Safe Mode

Hello,

My E65 started having Transmission Fail Safe Mode where I cannot go Reverese. If I restart the car most of the time I will be okay. But I noticed the hotter the engine is (the longer it has run) the more difficult it is to place it in Reverse, even after restart. When the car/engine is cold, I have no issues. So yes, after 20-30 mins of driving the problem starts.
I read few posts about different solutions, but I have not read a post where it was confirmed what the issue is/was.

If it is the Mechatronic Seal Adapter, can someone tell me how I replace it myself? How do I get to it?
Any pictures would be VERY helpful.

Thanks!

I would start there. Replace the mechtronix sealing sleeve an the adapter. You have to remove the valve body in order to replace the adapter if I remember correctly. As for the sleeve its rather the easy part. Also change the filter an pan while you there. I think some one did a DIY on this.

Do you have an illustration how to replace the adaptor?

I Don't even know where or what the adaptor looks like
