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.

Thanks. Illustrations are very helpful. So it's pretty easy to get to the sleeve once oil panel removed?

Sometimes my car suffers a big jerk while driving and once it gave this error "transmission failure". So I need to replace the mentioned mactronix adaptor to get rid of this jerk issue?

Hi folks, I would really appreciate an expert reply, my car gives a very annoying jerk usually while driving in low gear. Initially it was rare but now it has become more frequent. Sometime the jerk is followed by transmission fail alarm taking car in safe mode. The alarm is cleared once it is restarted after sometime (not immediately).
My mechanic suggested there is a problem with valve body but later he found it is okay and the problem is inside gear!
The mechanic suggests to open the gear box and make overall but costs a lot.

Any expert opinion will be highly appreciated.

Thanx in advance

E65 Transmission Fail Safe Mode

I had the same problem ...how does he know its the gear problem inside. ? .. Why does he say this ? .. My problem. Was caused by the previous owner having wrong oil in it .. I put BMW oil and replaced pan ( always replace the sump) .. And the mechatronic seal ) problems all gone now . When the wrong oil was inside in the morning when the car is started when I put in reverse the car would go fwd ( cuz the oil was thicker and caused problems) .. So investigate on that first and also rest the transmission adaption settings

Previous owner is friend so I know he had the wrong oil - even when the numbers matched the oem specifications !
