Sorry for being new here and jumping in with a question but here it goes.

My transmission does a few weird things. At 60mph light throttle I can see the engine rpm jump from 2000 to 2300 with a little jerky motion in the car. A couple of other things the car does, sometimes when I am going about 45 with very little throttle the car studders until I gas it and it downshifts. Sometimes I also notice vibration at a stop in drive. This vibration goes away when if I shift into neutral.

I replaced the filter, fluid (mobil synthetic, but not a full flush) and diff fluid. Prior to replacing the diff fluid I noticed a little binding on tight turns in the parking lot but that seems better now..

Any ideas on what I need to do.

Thanks, Jason
