Hyundai accent transmission acting up was created by Automaton09
Hi.
Please I have one question.
We replaced the ECU in a 2014 Hyundai accent only to discover that the transmission does not change properly and causes the car to jerk after gear 2.
It is possible that the ECU is not compartable.

Thanks

Do you have a bi-directional scantool? You, likely, just need to reset the PCM/TCM Adaptive Values.

The PCM or TCM contains logic to adjust solenoid duty and line pressure as needed to compensate for normal clutch wear over the life of the transaxle.

I am assuming it is a used ECU.

I use the aultel elite. I think this should be able to do that. I've never done it before, can I have the steps.

I am not familiar with Autel (or Hyundai, for that matter), But it should be under Transmission control. Look for "Functional Tests", or something similar. You are looking for "Adaptives Reset", or something similar.
