Pro Mod SFI Ultra Cased 3 Speed Turbo 400 Billet Transbraked Street & Strip w/4″ Tail Great for your big HP street, rod or Race Car. We have upgraded the NASA Billet input shaft with new drum, a Billet Transbraked Reverse Manual Valve Body for harder manual shifts and Transbrake Launches. We have also upgraded the intermediate drum to a Pro Mod Billet 36 Element Drum & Sprag assembly which increases the strength and HP rating of the gearbox and rollerized the output shaft.

We have rebuilt with quality ALTO Clutches, steels and bands, re-configuring the pump to high volume and adding the Deep cast alloy pan to increase the oil capacity, strengthening the transmission case and cooling the transmission oil.
