auto transmission shutter, 2 to 3

Ive got an 03 Tib auto, at 50,000 it started shifting harshly and hesitating between 1st and 2nd, 2nd and third. I took to Hyundai under warranty, they put in a new tranny. After 1000 miles, it started doing the same exact thing. I took it in again and said I had heard of a TSB on this issue and it was computer related, they said no its not and put in ANOTHER new trans and guess what, now its doing it again!!!! Anyone know of the TSB or what is causing this, thanks. They say no codes are showing.

what could be happening is that they are not resetting the adaptive learning process for the trans. and like you said the car could have an ecu reprogram that they are not performing. i will check on it for you when i get back to work.

yes, there is a TSB for the 03 Tiby, it may need a TCM replacement

thanks for your input... They put in a new transmission control module this time, and voila, its still doing it from 2nd to 3rd. They say its only doing it when the car warms up, now they want to put in a third transmission in three months..... wtf?????

well if they replaced the tranny and tcm then that means there is an electrical problem with the harness.
