hey guys...got my tranny built...i write my own tunes...but when i write them i leave the engine torgue tables stock because that has to do with the defuel...These tunes have been for daily driving....but leaving from a red light just cruising maybe 1/4 throttle from 1st to 2nd it revs up to maybe 2000 rpm and then shifts,,,it doesnt defuel any there?? is this correct?

Also from 2nd to 3rd it hessitates to go in third..like it kinda jumps the truck like i hit a bump in the road every time...is there anything i can do to fix these two issues...i have tried a duramaxtuner tune and it does the same thing...so any suggestions?

What happens with a stock engine and trans tune?

Nick

what parts were put into into the "fully built allison?"

it shifts harder when i put a stock motor tune...but the trans tune is stock....i am sure it shifts harder with stock because its not use to thoughs shifts...but i am sure its in the tune...i just was needing help with a daily driver tune and i had talked to some guys that said tey use race tunes.....and a race tune gets good mileage...

alto chutches..work on valve body..precission converter..and more..is it the valves sticking in the trans?
