Idk what I rev at. Mine doesnt even have a tach. I feel like buying a small one, just to know wtf the idle is doing. It seems normal, but Im curious to know, the cold, warm, driving, shifting, etc...
What do you mean tranny clunk?
You should check the pedal assembly. When I bought it, it was grinding gears because the clutch rod wasnt being depressed all of the way because the clutch assembly had worn enough to have some play in it. It eventually snapped and I had to get a new pedal assembly. I guess this happens to a lot of Rangers from different years... the pedal assembly is aluminum. I think the guy sold it to me thinking it had a tranny problem, because he lubed it enough for me to get home and not notice. It was bathed in grease.
