Step-by-step guide to installing a Stage 1 Shift Kit on a 2nd Gen TSX, including common mistakes and checkpoints for a cleaner shift feel.

Quick Answer

Install the ACUITY Stage 1 Shift Kit on your 2nd Gen TSX by replacing the shifter base and cable bushings—this reduces slop and sharpens shift feel without removing the entire shifter assembly.

Why Start with Stage 1

The Stage 1 kit is an entry-level upgrade that pairs compliance-reducing base bushings with spherical cable bushings. It targets the most common source of sloppy shifting without requiring you to replace the whole shifter assembly. This makes it a practical first step for TSX owners who want a more precise feel on a budget.

Tools and Prep

You'll need basic hand tools: a socket set, screwdrivers, and possibly trim removal tools. Before starting, ensure the car is on level ground and the shifter is in neutral. Disconnecting the battery is not required for this install, but it's a good habit if you're working near electrical connectors.

Installation Steps

Access the Shifter Assembly: Remove the center console trim around the shifter. Use trim tools to avoid scratching panels. Disconnect any electrical connectors for the shift indicator or illumination. Check that all clips are released before pulling—forcing the trim can break tabs.
Remove the Shifter Base Bushings: Locate the base bushings under the shifter assembly. Unbolt the shifter base and carefully remove the old bushings. Note their orientation before removal. Take a photo before disassembly to reference during reassembly.
Install the New Base Bushings: Press the new compliance-reducing bushings into place. Ensure they seat fully and align with the mounting holes. Reinstall the shifter base and torque bolts to spec. Do not over-torque—this can distort the bushings and defeat their purpose.
Replace the Cable Bushings: Access the shifter cable ends at the transmission or shifter side. Remove the old rubber bushings and press in the spherical cable bushings. Verify they rotate freely. If the spherical bushings feel stiff, apply a small amount of grease to the pivot points.
Reassemble and Test: Reinstall the center console trim. Start the car and test each gear, including reverse. Ensure the shifter returns to center and there's no binding. If any gear feels notchy, double-check bushing alignment and cable routing.
