ok well i have a 95 trans am it is a 2.73 car....i just installed the 3600stall and 3.73...the car does not have first gear u can put in manually...so i cut a ruuber *** off and made it so i can put it down in 1st. now with the stall the computer makes it shift when i have it down in 1st to 2nd and back to first again by itself could a tune fix it. what should i do??????

btw: first gear would to that sometimes with the 2.73 and stock stall but not as much... when everything is working right it was nasty gear... i just dont know if this is bad for the transmission or not

 

TTT

 

you could just be loosing first gear for a while i didnt have first gear and it just turned out to be bad sensor
