95 E300 Diesel clunk shifts and some tire roll in park..
 

1995 E300 Diesel 80k miles
124 body style with 606 engine.

I sometimes get a clunking during hi-way shifts, and shifting from park on hills.
I also have a slight rollback shift into park if not on level ground.

I was wondering is this sounds like a Flex disk on drive shaft or something in the transmision or rear end?

How do I diagnose?

Thanks in advance for your thoughts,
Jack

For the slight rollback - it's normal, use the parking brake.

My guess at your shifting noise would be transmission mounts. The clunking only happens at highway speeds? During downshifts or upshifts?

My 95 has slight rollback, the cluck can be as simple as modulator adjustment. I have a slight cluck at time from the ASD but it si not all the time 149,000 original tranny
