Transmission is a borg t5 5spd mannual, with hopes of going to a t56 6spd by the time snow hits again. and this isn't a daily driver so i thnk the lower gears will be fine with the overdrive trans, I'm thinking the 4.11s because mostly city stoplight fun and strip maybe auto x this summer , and i guess I'll leave everything where it's at for now.except get some exhaust on it before dyno days, I havnt ran motor higher than 5800 but thinking its only guna make power slightly higher then that but I guess wel have to wait and see
