I just experienced this problem last week for the first time.
What happens is after I place my shifter into park, the van rolls forward or backward depending on the slope. There is a loud thumping sound till I step on the brake and try to get the shifter into a locking position.
This never happened before in the 17 years I had this van.
My engine is running in good order and the transmission runs very well.
I hate the idea of keeping 2 bricks in the van to block off the wheels when I park.
If there is a solution or a source for repair please touch base A.S.A.P.
