Have a previous discussion about my trans issue:
Then decide to have a rebuild and still have shift issue between 20 mph and 40 mph. Engine rev high about 2500 when it accelerates from below 20 to below 40. the rpm stays about 2000 and does not come down even the gas pedal is not pressed. if pressing the gas hard, the rpm rev high around 2500 until I feel the shift and rmp drops to about 1500. I guess that rpm should be right with speed below 40 mph. even that, the car does not move that crispy. feel like stuck there like glue.
Speed over 40 mph feels reasonable.
Need to open up the shift cable cover to see if the TC has been replaced by mechanic or not.
