    GM 4L60E

    This transmission includes the bolt-on bell-housing to fit GM LS-Series engines (Pre-LS engines should use transmissions 555-603010 or 555-603015).

    This transmission can also be used in an older vehicle when converting to an electronically controlled overdrive transmission. The conversion to older vehicles will require the use of a transmission controller, crankshaft spacer, special cross-member, driveshaft changes and other modifications (these parts are not included with the transmission).

    • Handles Up To 450HP
    • Heavy Duty Sunshell
    • Heavy Duty 3-4 Clutch Pack
    • New Electronics
    • Reman Pump with New Rotor Vane Slide and Stator Support

    Performance Transmissions that Won't Bust the Budget

    These transmissions are remanufactured with a performance shift kit and all new bands, clutch plates, steel plates, seals, gaskets, etc. to consistently handle up to 450 horsepower with minimal effort. A rebuilt front pump and recalibrated valve body ensure smooth-running transmissions with lasting reliability. The chrome pan with drain plug (except where noted) makes them look as good as they go!
