    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).

    1996-02 Camaro/Firebird must reuse their old 4L60 tail-shaft housing since this transmission does not include the special housing that has the mount for the torque link.

    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).

      Features:
    • 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
    • Shift Kit
    • Corvette Servo
    • 0.500 Boost Valve

    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!

    Will this fit the 2004 gto 5.7 ls1 without changing the drive shaft? 

    Asked by: TwinTurboGTO
    If your car has a 4L60E already, this should be a direct swap.
