    Why it fails

    Excessive wear in the PR valve bore is behind most of the problems seen in this transmission, so it makes sense to repair the bore while the unit is apart.

    Shops that already own the reamer and guide can use refill kit 4T40E-PR5, which has enough parts to fix five transmissions.

    What's included

    • Pressure regulator valves and springs
    • Pump slide springs
    • Reamer and guide
