You almost sound like you know what your talking about.

Did you check the gear ratios? The Cobra T56 6th gear is the same as the 5 speeds 5th gear.

yeah, your grammar is pretty bad so your post was annoying to read.

if you had checked THE STICKIES you would find this thread showing you exactly how to change out your t45/t3650 for a t56 from a cobra.

and jmac no 6th gear is lower than the 3650 5th gear. all the gear ratios are on there. however its not going to affect gas mileage that much. it will be years before the tiny amount of gas saved outweighs the 1500+ you need to swap the tranny out.

That is what I mean. The difference is minimal. If you want an actual difference in the ratio, you should look into the Viper Spec.
