So I put a new tranny mount in because the stockie was broke in two peices. That solved it for a while.. but now I have a giant clunking comming from the rear again.. its like when im decelerating and tap the gas it goes CLUNK and then accelerates. There is a definite lag in acceleration.. I think it might be the ring gear going out... when accelerating its like im holding the clutch 1/2 in.. accelerating then letting it out smoothly. EXCEPT its an auto.. but that still doesnt explain the clunking. I think im going to have to throw down some serious cash on this. QUESTION: Could this be the converter going out as well???

This might needed to be moved into drivetrain but I want as much exposure as possible.

Any and all thoughts/opinions/advice will help
