Tools Needed


Steps to Fix the Problem

  1. Disconnect the Battery

    Use your 10 mm socket and ratchet to disconnect the negative battery terminal. This will help you avoid any electrical problems during your work.

  2. Locate the Shift Solenoid

    The shift solenoids can usually be found on the transmission of your tZero. Check your vehicle's manual to be sure about the location.

  3. Drain the Transmission Fluid

    Put a drain pan underneath the transmission and remove the drain plug with your ratchet, then let the fluid drain completely.

  4. Remove the Old Shift Solenoid

    With the fluid drained, you can now access the solenoid. Use your screwdriver to remove the solenoid's bolts then remove the solenoid itself.

  5. Install the New Shift Solenoid

    Place your new solenoid where the old one was and tighten the bolts. Make sure it is in place firmly.

  6. Refill the Transmission Fluid

    Now, refill the transmission with fluid. Be sure to check your vehicle's manual for the exact amount required.

  7. Reconnect the Battery and Test

    Reconnect the negative battery terminal. Start your tZero and take it for a short drive to ensure that everything is working correctly.
