Re: Another gearing question

Will be about about the same as a stock truck with 3.73 and stock 29" tires up to 3rd gear. Not accounting for extra rolling resistance and tire weight. Then will drop about 800 rpm going to 4th (overdrive). Should be fine. Nice thing about the 6l80-90 is there is an extra gear in-between 3rd and 6th. With 6th gear being fairly close to final overdrive of 700R4.
