I installed a Transgo shift kit about 2 months ago. I set it at stage 2. I noticed at full throttle during the 2-3 shift, it will shift to 3rd, then drop back in second and then shift back to third. All in the matter of 2 seconds. It does it everytime at WOT. Has anyone else experienced this? and does anyone know why it does it? Any info is appreciated. Thanks Dan

 

Are you sure its not your Torque Converter locking up?

 

maybe your superchip is having an issue with the shiftkit and causing the problem.

 

I'd call Transgo. That isn't right.

 

It seems a while back before I had my kit I read here that someone was experiencing the same problem, and they had a superchip too.
