1999 ML320 sudden lack of shift
 

Hello

This is posted for a customer.

1999 ML320 sudden lack of shift.

32 point MB dealer service followed by unexplained failure of transmission to shift.

One hour later normal function.

Three hours later parked at mall, came back to vehicle, half way out of clean level parking lot, loud crunch/thump, described as if running over large road junk, transmission stopped shifting, and further attempts are futile.

Suggestions needed.

Computer controlled systems need to be scanned for problems.

Does the trans engage any gear at all???

Answer
 

I just got off the phone with her.


First and reverse, no others....

Since the truck will move...I would have the trans & transfer case computers scanned for codes!

thank you
 

I have sent them to the local MB dealer.
