Thanks for the help guys.

I know the TC won't cause a misfire but the way my truck act it was the easy explanation .. It only do it around 100km/h going uphill in 5.. If I downshift it's all good.. Or sometime when it's cold outside and I just started it, it feel like my wheel are full of snow.. So those are the main reason I forgot to said that lead me to the TC .. Since the plug are new I'll check the coils.
