I just totally replaced the entire transmission on my H23 '92 'Lude (AUTOMATIC) and now it's over-revving through the start of the gears and having trouble getting a started on acceleration. It will rev up, and then slowly start catching first gear, and then have a pretty jolty shift to second (same through all gears). I only put in about 2.5 quarts of ATF... could this problem be due to not having enough ATF or is it a bad torque converter??? Any help would be greatly appreciated as I've never really dealt with automatic trnasmissions before...

 

start the vehicle and check the trans fluid. if it is low on the dipstick while running fill until at proper level. SHOULD cure the issure, if low.
