    gt5 looks like 4.10 ratio from everything I see, tranny, i would think it would be 4l80e or 4l85e, since those are the truck trannys, but it may be the 65. O and btw 4 u *le cough* TTT *le cough*

    the 80 and 85s are 3/4 and 1 ton trannys though, arent they? this one is a 327 1/2 ton, so i dont see where a big tranny would be used.
