W4A33 Shift Solenoid Test Block

The W4A33 Shift Solenoid Test Block, machined from 6061 aluminum, enables precise testing of W4A33 transmission solenoids. It allows controlled air pressure and voltage application to assess solenoid response and detect common failures, such as solenoids failing to close after voltage removal. Also makes it much easier to clean and flush debris out of solenoids after a transmission failure. Compatible with 1g, 2g, and RVR models.

Uses 1/4" npt fitting for air supply (not included)

*When using on 1g/rvr solenoids, will need to block lock up solenoid provision. This can be done with the AGR reducing pressure solenoid block off*
