on the way back from the track i noticed that the car was acting different. at around 35-40 mph the torque convertor locked then unlocked then locked up again. this was under light throttle just easy up to speed.

i have a vig 3200 stall, tranny cooler and a shift kit. i also have hptuners but dont think thats the issue. so what do yall think of this???

by the way, got my new personal best of 12.58@109 w/ 1.85 60 that day.

Check codes and check for and engine miss even a minor miss will cause the pcm to unlock the converter
