    I changed my trans fluid today and the whole pan had shavings in it, so now i'm looking for a good used one again. I was woundering if the 3.1 GP 4t65e are the same?

    I doubt the 3.1 will work as I would think it has a different bell housing pattern. IIRC anything from 98-02 will fit. 03 was a separate beast of its own. There will be some differences in the lines if you go with something newer than a 98 trans. I actually went backwards on my 00 GT and installed a 98 trans. Had to change the lines to the 98 style. Got them at the dealer for about $50 for the pair.

    Ok, Not worried about lines, the lines and trans i have on there now are from a 03 Impala. I can't find any 98-02 trans that are under 150k around here. Are the 04+ GP trans different?
