I never actually saw the car that my motor and tranny were pulled out of and supposedly it was out of a 2005 grand am gt (unit was brand spanking new and had 0 deposits on the rebuild).
I am having a problem finding out what type of 4t45 it is. I have tried copying PCM tables for a 04 and a 00 grand am gt and my pcm is flashing that I have the incorrect gear ratios. I have also tried a 00 SE to no avail.
Is there any number anywhere cast onto the trans that I can use to determine what type of trans i have (obviously its not the old 4t40 or the malibu stock pcm tables would work)?
Any help on this would be SUPER ! :P
