    4. NOTE: Solenoids are calibrated from the factory and are not all the same. To replace a solenoid, match the replacement solenoid type (normally high/normally low) and the band number with the original solenoid or harsh/erratic shifts, harsh/soft engagement or damage to the transmission can occur.

  5. Remove the 26 main control bolts from the main control.
    6. NOTE: Many components and surfaces in the main control valve body are precision machined. Use care when handling the upper and lower valve body or damage can occur to the machined surfaces.
    NOTE: The main control is positioned on the lower valve body before separating the upper valve body from the lower valve body to keep the solenoid dampers from falling out of the lower valve body.
