95 s-10 5 speed 2.2 liter 101,000 miles. I'm getting this rattle/grinding noise from the rear of the tranny. This noise happens at an rpm level just above idle(I don't have a tach) in gear or not, with clutch in or out. Driving slowly or sitting still will produce the same noise, but will go away at higher rpms. Any ideas of what may be causing this? I am taking it to a shop tomorrow and would like to be armed with some info. I also checked the fluid and it is ok. Thanks for reading.

throw -out bearing is my best guess, can't hear it from here.

Thanks. It turned out to be the cat converter was coming apart from the inside.

have a 98 s-10 with same engine, same cat problem....man that is a nappy sound you don't soon forget....lol
