Had this problem before but it seems worse now with the engine work. Did a full throttle run yesterday and it hits the rev limiter on the 1-2 shift. Used to do it on the 2-3 and sometimes the 1-2 shifts. I used to blame it on the 3.73 gear swap even though the Hypertech should have fixed it. Now I have custom programming. My fluid was a little low but I doubt that’s the problem. I’m hoping it’s a programming issue, that it just isn’t shifting early enough and overshooting. Or… tranny is turning to poop. Any suggestions on figuring this out? ---

could be cause you got the incorrect tire size on the car and the comp is thinking the speedo is at a different mph but your rpms are off. tire size does effect your revlimter. i hit mine a few times when i went back to stock size tires after having larger ones one. or your tranny could be going sour
