Pro Street Stage 4 SFI Ultra Cased TH-400 Billet Transbraked Street & Strip w/4″ Tail Great for your tuff street, rod or Race Car. We have upgraded to a 300M Billet Input Shaft, Billet Steel Hub to 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 Case Hardened Alloy 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.
