what 2 different trannys are there for the 99 grand am gts,i get to enjoy the pleasure of buying a new one within the next week,i think i have the 4t45e,but im not sure and just wanted to know the 2 kinds.yup had the car two months and so far the power steering and tranny have gone out man i hate to love cars..:disappoin

All GTs have the 4t45e and SEs have 4t40e and new,
they are not cheap.

Good Luck
