Last fall I purchased a used 2001 Jeep Cherokee with about 60,000 miles and no towing hitch. The transmission has a significant thump when it is shifted into drive when warm.
In the morning there is no thump - the engine and transmission are cold. But if I am running around town doing errands, every time I shift into drive there is a noticeable noise and slight lurch. Sometimes it will even thump after sitting in the parking lot 8-10 hours after work.
Last winter is wasn't so bad because the engine and transmission would cool down much more quickly.
Any ideas or comments?
