C-4....as C-6 are very heavy and bulky!!!! You should look into Lentech they make a really good auto tranny any kind from manuel valve to regualr auto's!!!! Sure you'll pay, but you pay for what you get!

i'd assume a built C4...BTW what are you doing with the old trans?

I went from auto to 5speed and will never look back unless I build an insane insane strip only car, but for now I would not go back to an auto there is nothing like banging gears. That and I am A.D.D so I need something to do!any of you ever regret going auto from 5spd? as far as a street/strip car

any of you ever regret going auto from 5spd? as far as a street/strip car

Just keep your 5speed set-up!Thats what i'm affriad of, i'll hate it! I like shifting gears as well. Maybe now my trans is new i can actualy drive and shift it? peace

There are pros and cons to the manual vs. auto......i.e. Pro for auto would be you never miss a gear during important races, a Con for auto would yes, you do lose more horsepower through an auto another Con for auto would be during street duty (where I expect most of your driving will be) you can't down shift/have proper control of your trans...another Con for auto you have to worry about torque converters and there stall ratings and whether the conveter is lock or not.....now Pro for manual is you don't lose as much horsepower through it and a Con is yes if you can't/don't know how to properly drive a manual you can miss gears.....another Con for manual you have to worry about slipping clutch, but if you get the right clutch for the job this should not be a problem. You have also got to think about weight differance the auto weighs alot more than the manual...so that may take into effect. I really can't say what amount of power you lose through a auto cause it is different for every car...but I think the general rule of thumb is you lose alittle over 3% more than a manual. Now the trans I am using is Tremec TKO600 with/aftermarket lugs(easier to shift into gear).....with a Spec Stage3+ clutch....now trannies and clutches are NOT rated in RWHP they are rated in RWTQ.....I am making over 600rwtq and supposedly my tranny set-up gives out at 600, but for over a year and half the tremec has not let me down and the Spec clutch keeps on grabbin'. Any other questions feel free to ask!What is the power loss running an auto verses a 5 spd. FLO what trans do you have with clutch? peace
