    Manufacturer's Part Number:

    Increase the Performance of Your Transmission

    These shift improver kits increase the performance of automatic Powerglide/TH350/TH400 transmissions. They are cost effective and include necessary valve body plates, as well as gaskets and complete instructions. Available in your choice of Street/Strip and Heavy Duty kits.

    Street/Strip: For hot rod applications - substantially increases line pressure, and removes the delay out of the shift.

    Heavy Duty: For towing or RV applications - removes the delay out of the shift and not quite as harsh as the street/strip version.

    Some parts are not legal for use in California or other states with similar laws / regulations
