I did a transgo hd2 shiftkit for a friend in his 4.3 s10 blazer extreme today. It shifts great everything is good. It will go into limp mode randomly then you can let it sit for 5 minutes then its fine. We drove it like 40 miles and its did great, then went into limp mode then let it sit then its fine. No codes stored, what could cause this? If it was something with the shift kit then it would be all the time not randomly, right? Please help, Josh
