I was just curious.

If this helps, I have a 1995 Cavalier with a 2.2 I4...almost 181k
First, When I'm around 30-40mph (2nd Gear?) and I take my foot off the gas, then put my foot back on, it seems to be slipping, or what I think of it as slipping (It's making this grinding noise, and I have to step on the brake and slow down to 25mph to get going again.)

Second, My sister has a 95 Saturn SL1 with a 1.9 I4...she's getting rid of it for engine problems. It only has 129k...I was wondering that since Saturn and Chevrolet are both GM, her car is similar in size, with only difference being her car has a smaller engine, is it possible for me to take the trans out of her car and put it in my car?

Thanks.
