    The stock gtp trans has a 2.93 gear ratio and the stock gt has a 3.29 ratio. To make one work in the other you need a tune.

    Same transmission...

    '97 SE/GT's had the weak vacuum powered 4T60e...you want to stay far away from them...
    '97-'02 GT/GTP's had the 4T65E (GT) and 4T65E-HD (GTP)...gearing is said above^^
    '03's had the 4T65 BUT...can't be used in any other '97-'02 car because the internal electronics and valve body is different.
    Sold WBody's: '03 Blue GTP/'98 Green GTP/'98 Silver GT/'05 GXP
