Has anybody had any problems with their trans not shifting on the dragstrip? I've got stock gears and trans, but I do have a JET chip, but the last time I went to run the trans would not shift at wide open throttle for some reason. But off the track on the road it shifted fine. Would it have something to do with the trac control? I have it turned off when I run. I pulled the chip out which in turn had to unhook the battery so everything was cleared out, but it stilll wouldn't shift. Any ideas????????
