Car rolls in Park

Recently, my '83 300D has started rolling when in Park. This happens even on small inclines.

I would stop, put the car in Park, shutoff, remove my foot from the brake pedal and the car starts to roll backwards. When rolling backwards I hear a clicking sound coming from underneath the car.

Pushing the brake pedal again and applying the emergency brake (left foot) stops the car.

What would cause this?

1...perhaps the parking prowl inside the transmission is busted.
when I shift into park my car will rock a little forward/backward until a clank is heard. that is the parking prowl catching.


2...perhaps when u shift into park, the shifter is not putting the trans into park fully...that would be a problem in ur linkage underneath in the tranny tunnel.

just a guess thou...

I would look at the parking prowl. I had a van that did this and the locking key had been sheared off . This was caused by putting the van in park before the vehicle was completely stopped.

I second the idea to check the linkage. The bushings in your shifter are probably worn out or missing, and not shifting the trans into park. If the shifter is ok, dig deeper.

My 300D did this until after I replaced the bushings in the shifter mechanism (not the bushing underneath the car).

Mine did the same thing, plus would hold the 2-3 shift for a rediculous amount of time. Turned out to be the shifter bushing, which was fixed for 50.00 total at the local indy benz guy. Car shifts waaay better, probably because it had no idea what gear it was in due to the shift selector being out of whack. On these cars, it seems to be little simple things that wear out.

My 300SD starting doing the same thing, crawled underneath and no shift bushings left. Ozarks engineered some from rubber-like fuel line and that worked fine and solved problem.

Here is a website that has a little tool to install the new shifter bushings with: www.**************.com

It definitely would be a good idea to use the parking brake!
