The ujoints don't clunk and the transmission doesn't jump when I change from Drive to Reverse, or Reverse to Drive.

sorry i seam to have dropped your question.this seams to be a internal problem in the trans.its more noticed when your at higher speeds.youll need to take it to a trans shop and let a specialist drive it.fyi you only test the motor mounts with the rev to drive test.use a pry bar to check if the trans mount is broken and u joints can clunk if they get bad enough.ty for using 2carpros

I have replaced the Throttle Position Sensor and the transmission now shifts 3-4 and 4-3 mormally.
