- Thread and seal
- Same thread size, and use a new sealing washer if the original had one The switch screws into the transmission case, so a poor seal leaks fluid.
- Connector
- Same connector and terminal count as the original Some switches also feed reverse signals to the radio, camera or other modules.
- Torque
- Tighten to the specified torque, not by feel Overtightening can damage the switch or the case threads.
