5.2 Installation Steps (General Guide)
- Prepare Vehicle: Park the vehicle on a level surface, engage the parking brake, and place the transmission in neutral.
- Remove Old Shifter: Carefully remove any console trim or boot covering the existing shifter. Disconnect the shifter linkage from the transmission. Unbolt and remove the old shifter assembly from the vehicle floor.
- Inspect Area: Clean the mounting area and inspect the shifter coupler and bushings for wear. Replace any worn components as necessary.
- Install New Shifter: Position the EMPI Trigger Shifter assembly into the mounting location. Secure it with the appropriate bolts and hardware. Ensure the rubber shift boot is properly seated to prevent debris from entering the mechanism.
- Connect Linkage: Reconnect the shifter linkage to the new shifter. Ensure all connections are secure and free of excessive play.
- Adjust Shifter (if necessary): Some shifters may require minor adjustments to ensure proper engagement of all gears. Follow your vehicle's service manual for linkage adjustment procedures.
- Test Functionality: With the engine off, cycle through all gears (1st through 4th, and Reverse) to ensure smooth engagement and proper operation of the reverse lock-out.
- Final Assembly: Reinstall any removed console trim or shift boot.

6. Operating Instructions
The EMPI Trigger Shifter is designed for precise and quick gear changes with an integrated reverse lock-out mechanism.
- Standard Gear Selection: To engage forward gears (1st, 2nd, 3rd, 4th), simply move the shifter lever through the standard H-pattern. The reduced throw design allows for shorter, more direct shifts.
- Engaging Reverse: To engage reverse, pull the trigger loop located on the shifter shaft towards you. While holding the trigger, move the shifter into the reverse gear position. Release the trigger once reverse is engaged. The trigger mechanism prevents accidental engagement of reverse during forward driving.
- Disengaging Reverse: To disengage reverse, move the shifter out of the reverse position. The trigger will automatically reset.
7. Maintenance
Regular maintenance ensures the longevity and smooth operation of your EMPI Trigger Shifter.
- Lubrication: Periodically (e.g., every 6-12 months), inspect the shifter's pivot points and linkage connections. Apply a small amount of high-quality grease to these areas to ensure smooth movement and prevent wear.
- Inspection: Regularly check the shifter assembly, mounting bolts, and linkage for any signs of looseness, wear, or damage. Tighten any loose fasteners.
- Cleaning: Keep the shifter and surrounding area clean. Wipe down the chrome shaft and plastic components with a soft, damp cloth. Avoid harsh chemicals that could damage the finish.
- Boot Condition: Inspect the rubber shift boot for cracks or tears. A damaged boot can allow dirt and moisture to enter the shifter mechanism, leading to premature wear. Replace if necessary.
8. Troubleshooting
If you encounter issues with your EMPI Trigger Shifter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Difficulty engaging gears | Loose or misadjusted linkage; Worn shifter coupler/bushings; Lack of lubrication. | Check and adjust shifter linkage; Inspect and replace worn coupler/bushings; Lubricate pivot points. |
