that out of nowhere started clunky/harsh 3 > 2 shift. Even though the car is almost new I have no warranty because it was imported to my country. I am alone in this. 
I read that reprogramming or resetting the TCM can help to solve, how can I do this? The only option is to pay a fortune for the HP Tuners? I just want to reset to see if my transmission is back to normal.
I have not been doing well for a few months now and I am selling my stuff, and this just happens to me. I want to fix the fault to try to sell the car so I can stay alive. Thanks |
I posted in the other thread but...
Try this because it may not be the transmission. Have your mechanic check for a loose axle nut. I had the same issue where it was clunking on downshifts and thought it was the transmission. Was just a loose axle nut clanging on certain downshifts.
