I have a 2002 Ford Escape V6 auto transmission with 91,000 miles. When it shifts it is a bit rough. I don’t remember this always being there but maybe it was and is just a bit more noticeable. I have been told this is a Volvo transmission. I pull a trailer with an ATV occasionnally but the the thump is the same with or without the trailer. Thanks for any help in diagnosing this! DebG47 ---

I can count about 10 things off the top my head that will “thump.” Can you describe the problem better? Is the thump always associated with shifting, for instance? ---

When this happened to me I was told by my local independent trans shop it could be a worn pressure solenoid. He dropped the pan, drained the fluid and changed the filter, refilled it and the harsh shift disappeared. (some vehicle trannies don’t use filters, but use a screen instead) For about 2k miles. It wouldn’t clunk after sitting parked for a short time, but then it would shift harshly periodically. It hasn’t done it since last June, but I change the tranny fluid/filter every 30k miles anyway.
