Build it yourself and save! Our Monster Rebuild Kits are moderately priced and offer an exceptional value for the performance minded street enthusiast. This 4L80E SS rebuild kit is rated to 750hp and 700 ft lbs of torque. Everything is included that we use in our transmission, see the list below for details.
Engineered to Dominate, the 4L80E SS Mega Monster transmission is tough enough to withstand the rigors of even the toughest street machines delivering tire-spinning shifts race after race. It is ideal for vehicles powered by engines producing up to 750 horsepower / 700 ft lbs of torque using pump gasoline. Equipped with a Manual/Automatic valve body, most units allow you to manually shift the vehicle into each gear change or, by placing it in the drive position, remain fully automatic. In either mode, you get a racetrack shift that bangs through the gears giving you all the right to say "Eat My Shift!". When you use the manual gear selection feature, the Mega Monster upshifts and downshifts when you move the shift lever, please note, in order to have complete control of the RPM shift timing you must upgrade to a full manual valvebody. When you select the normal drive position, the transmission retains its firm, automatic shifts for the ease of driving you look for in an automatic transmission.
