Tuff Street TH-400 Chevy Street & Strip w/4″ Tail Great for your tuff street, rod or Race Car. We have upgraded the valve body to a Reverse Manual Valve Body for harder manual shifts. We have upgraded the intermediate drum to a 34 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.
