Anybody got an idea why my transmission would be locking me out of 3rd at the track? It only does it on occasion but it seems to do it more frequently when Im spraying nitrous. Shifts perfectly smooth during regular driving. Its like there is a wall there and I have to fight for several seconds with it before it either goes or I just give up. I have put the redline fluid in the trans and installed the barton shifter bracket in hopes of fixing this issue but no luck. People at the track tell me my brake lights come on when it happens as well. I turn the traction control off as well as the stability control before every run and I have unplugged the skip shift solenoid as well. If anybody can help me figure this out I would greatly appreciate it.
