check to see if you don't have too much tranny fluid in your tranny. I recently had a clunking noise when I got mine back from a shop. I didn't ask them too but they had added tranny fluid. WAY TOO MUCH!!!
When I got so annoyed with the clunk and decided to find the source and checked the tranny I was so upset to find the source was the transmission, as the VX was at the shop for an insurance claim not for service.
I started the VX up and opened the fill plug and so much Tranny fluid came out it was about two quarts too much. after that the cluck went away.
Anyother time I had a clunk anywhere it was the driveshaft and ujoints that were in needing of a greesing.
