When i put the pedal to the floor and my tranny shifts, it feels like it revs and then shifts. could my tranny be slipping? do you think its from my increase in line pressure due to my hypertech? it feels pretty cool but i dont think it is safe.

 

what gears do you have? And is this doing this at any mph when you hit it?

 

sounds like slipping to me

 

Have you checked your fluid? Is it brown? Does it smell like burnt clutch? If so, then I'm sorry, I'm pretty sure your tranny is goin' down hill.
