Hi, I am having a problem with the gear changing. Usually is between 1st to 2nd or 2nd to 3th and 3th to 4th. It kicks and some times feel that is not the correct time to change the gear. feel like gear slides. Also when am at low speed 20km - 10km from 2nd gear to 1st and then stop it feels like a big kick that somebody hit you in the back. Some more information is that my TCU plate failed and has being repaired, but the problem there was before the plate failed and after it has being repaired is still happen. Also the gearbox oil-filter has being change every 40-50k km. Also i made a TCU reset with the kickdown pedal procedure and reset the TCU throttle through icarsoft MB ii. There are no error codes and my mechanic cannot find the problem.
Is there any chance to be something else ? Injectors? boost sensors? gearbox converter?
Please advice
