Tranny Recommendations for 600 HP

Depends on the use but and if your going to be racing it at all to avoid a Trans explosion I would do all of the below. If not racing all of below except the Billet Front Drum.

904 is cheaper to built for racing purpose cause their is no need for the billet front drum and it will handle your power fine.

I just bought all the parts for my 904... $480.00 for the kit and everything below except the valve body, billet front drum and sprag.

Billet front drum, red clutches, new steels, Kevlar bands, billet rear servo, HD band strut. bolt in roller sprag. Hd return spring module for front clutch pack, new pump gears, your choice of valve body & new billet band apply lever to match valve body.
