Part 5 of 7: Install the new transmission oil pressure switch

Step 1: Get the new switch out. Put the new switch onto the transmission.

Step 2: Install the mounting bolts to the switch. Tighten them down hand tight. Torque the bolts to 8 foot-pounds.

  • Note: Do not over tighten the bolts or you will crack the new switch housing.

Step 3: Plug in the harness to the switch. If you had to remove any brackets holding up the harness to the transmission, make sure you reinstall the brackets.
