109,000 Had the problem when I bought it in June. Changed the fluid and filter. Problem didn't get any better. When I "jump" on it in reverse the truck will shudder somewhat. Might be the worn clutch you mentioned. I assume reverse will eventually go away altogether. For now I baby it as much as I can when using reverse. am I prolonging the inevitable? Also will the reverse problem cause any other issues with the forward gears?
Thanks for the reply!!!
