wrong shifting points ? PCM ??

so i got my truck finally moving and put an exhaust on it. .

trans seems like its slipping the shift.. but then it slams into 2nd like a shift kit would feel like

the trans has under 600 miles .. yes less then 1k miles on the rebuild from what my mechanic said.. has upgraded bands and a mild shift kit

i did 2 test runs with the pedal on the floor on the street.. and same thing..

could it be that my pcm was flashed for the wrong tuning.

its a 6.0 lq9 swap with a 4l60e ..

For what?!!!!

Apparently not your truck if you say stock gears for a camaro.

All PCM's are flashed, if not it wouldn't even run.

Tire height and gear ratio are two important things that have to be programmed in your computer. If they are not you will have issues. Vince
