I put this post in the Diesel section since the car is an '80300SD, but I didn't get any replies that answered my question. So, I will try here.

I just got the 300SD out of the garage for the first time this year and I noticed that the shift lever won't go into park when the engine is running. As soon as the engine is shut off, it goes into park easily.

Anybody have an explanation?
