    4L60E OE diameter .472” factory replacement boost valve and bushing kit fits both early long and late short style boost valve systems. No need to stock both types. 

    Corrects/Prevents/Reduces
    • Restores pressure rise
    • Protects transmission from extreme reverse pressure due to worn out  or cross leaking boost bushings

    Note that up to March 2005 the kit can be installed in the vehicle. However, in March 2005, General Motors gradually started adding an input speed sensor in this transmission which inhibits access to the boost valve assembly. On those with the added input speed sensor, transmission removal is necessary to access the boost valve.

    Includes:
    • USA-made hardened steel boost valve and bushing
    • Spacer
    • (2) Springs
    • Snap ring
