Easy Shift TH-400 Chevy Street & Strip w/4″ Tail Great for your tuff street, rod or cruiser. We have run the OEM style shift for the relaxed styled driver who doesn’t want to shift gears all day. 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.
