XJ Transmission Thump

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?

There are several things that would cause a harsh shift into drive; low fluid, throttle linkage misadjusted,u-joints worn/broken, axle back lash incorrect, hydraulic pressure incorrect, band mis-adjustment, clutch, band planetary component damage, or the converter clutch faulty. Coasty

Plus a bad engine or tranny mount, specifically I would look at the driver's side first. It is near the exhaust and can get heat affected.

sounds like a very fast idle speed to me
