hey guys need some help
Hooked my truck three times last Saturday and it would fall on its face at the 180' / 200' mark. I roll off the line, stand on it, then manually shift at aprox. 4000 rpm. At first I thought the tcm was overriding and shifting into fourth, so last pull left in second gear same issue, goes from 4200 to 2700 like someone flipped a switch. Has occasionally thrown an overboost code in the past, but nothing this time around. Had noticed it seemed a little week in fourth recently but I try not to run it to hard as trans is stock for the most part (trying to make it last till I can afford upgrade). Changed fuel filter tonight just to make sure, but no difference. Have one pull left this season and could use any suggestions. Truck would be competitive if I could get this issue taken care of.
