J 41364-A Neutral Position Adjustment Tool

1. Position the J 41364-A onto the park/neutral position switch. Ensure that the two slots on the switch where the manual shaft is inserted are lined up with the lower two tabs on the tool.
2. Rotate the tool until the upper locator pin on the tool is lined up with the slot on the top of the switch.
3. If the park/neutral position switch did not slide off the manual shaft, file the outer edge of the manual shaft in order to remove any burrs.
4. Install the switch to the transmission manual shaft by aligning the switch hub flats with the manual shaft flats.
5. Slide the switch onto the transmission manual shaft until the switch mounting bracket contacts the mounting bosses on the transmission.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
