Introduction to Installing a Short Shifter Kit on the 2020 Acura TLX

Upgrading your 2020 Acura TLX with a short shifter kit is one of the most effective ways to enhance your driving experience. A short shifter reduces the distance the gear lever needs to travel between shifts, resulting in faster, more precise gear changes and an overall sportier feel. Whether you’re an enthusiast looking to improve performance or simply want a more engaging drive, installing a short shifter kit can make a noticeable difference.

This guide will walk you through the entire process of installing a short shifter kit on your Acura TLX, providing detailed steps, helpful tips, and important considerations. No matter your skill level, following these instructions carefully will help ensure a smooth and successful installation.

Why Install a Short Shifter Kit?

A short shifter kit modifies the stock gear shifter to reduce the throw distance between gears. Here are some key benefits:

  • Quicker Shifts: Shorter throw distance means faster gear changes, which is especially beneficial during spirited driving or track use.
  • Improved Shift Feel: Most kits offer a more precise, mechanical feel compared to the sometimes vague stock shifter.
  • Reduced Driver Fatigue: Less movement needed for shifting can reduce strain on your wrist and arm during long drives.
  • Enhanced Aesthetics: Many kits come with upgraded shift knobs and polished or anodized components that improve the interior look.

However, it’s important to consider that a short shifter can sometimes increase shift effort or introduce a slight increase in noise and vibration, depending on the kit and installation quality.

Tools and Materials Needed

Before starting the installation, gather the following tools and materials to ensure a smooth process:

  • Short shifter kit specifically designed for the 2020 Acura TLX (verify compatibility with your model year and transmission type)
  • Socket wrench set (metric sizes, typically 10mm, 12mm, and 14mm sockets)
  • Torx screwdriver or bits (usually T30 or T40)
  • Flathead and Phillips screwdrivers
  • Trim removal tools to prevent damaging interior panels
  • Needle-nose pliers
  • Grease or lubricant (usually included in the kit or recommended by the manufacturer)
  • Clean rags or shop towels
  • Safety gloves
  • Service manual for the 2020 Acura TLX (optional but highly recommended for torque specs and diagrams)

Preparation Steps Before Installation

Proper preparation will save time and prevent damage to your vehicle or new parts.

1. Verify Kit Compatibility

Ensure that the short shifter kit you purchased is compatible with the 2020 Acura TLX and your specific transmission type (manual gearbox). Some kits cater to specific trims or transmission variants.

2. Park on a Level Surface and Engage Safety Measures

Park your Acura on a flat, stable surface and engage the parking brake. Remove the key from the ignition to prevent accidental engine start.

For safety, disconnect the negative terminal of the battery to avoid any electrical shorts or unintended airbag deployment while working near interior trim.

4. Gather All Tools and Parts Within Reach

Set up a clean workspace near your vehicle and organize your tools and parts. Having everything on hand reduces interruptions during the installation.

Step-by-Step Guide to Installing the Short Shifter Kit

Step 1: Remove the Shift Knob

The first step is to remove the existing shift knob:

  • Grip the knob firmly and twist it counterclockwise. Most Acura TLX shift knobs are threaded and will unscrew.
  • If the knob feels stuck, check for any retaining screws or clips that may be securing it. Use a screwdriver if necessary.
  • Once removed, set the knob aside safely as you will either reuse it or install the new knob included in your kit.

Step 2: Remove the Shift Boot and Center Console Trim

The shift boot and surrounding trim must be removed to access the shifter assembly:

  • Use a trim removal tool to carefully pry up the center console trim around the shifter. Avoid using metal tools to prevent scratching.
  • Once loose, lift the trim piece gently and disconnect any electrical connectors for features like heated seats or USB ports if applicable.
  • Remove the shift boot by pulling it up from the base. It may be held in place with clips or adhesive.

Step 3: Detach the Shifter Assembly

With the trim out of the way, you can now access the shifter mechanism:

  • Locate the retaining bolts securing the shifter to the transmission linkage. These are usually 10mm to 14mm bolts.
  • Use the socket wrench to remove these bolts carefully.
  • Disconnect any linkage or cables attached to the shifter. This may involve removing cotter pins or clips—needle-nose pliers are helpful here.
  • Once all attachments are removed, carefully lift out the stock shifter assembly.

Step 4: Prepare the New Short Shifter Assembly

Before installing the new shifter:

  • Compare the new short shifter parts with the stock assembly to familiarize yourself with differences.
  • Apply the supplied grease or lubricant to pivot points and bushings as recommended by the manufacturer. This ensures smooth operation and reduces wear.
  • Check that all hardware included in the kit is accounted for (bolts, bushings, washers, etc.).

Step 5: Install the Short Shifter Assembly

Installing the new shifter is essentially the reverse of removal:

  • Position the new short shifter assembly into the mounting location.
  • Reconnect any linkage or cables securely, ensuring clips and pins are reinstalled properly.
  • Fasten the shifter assembly with the bolts and torque them to the manufacturer’s specifications (if available, typically around 25-35 Nm).
  • Check the movement of the shifter to ensure it moves freely through all gears without binding.

Step 6: Reinstall the Shift Boot and Center Console Trim

  • Slip the shift boot back over the new shifter assembly and secure it in place with clips or adhesive as needed.
  • Reconnect any electrical connectors previously disconnected.
  • Snap the center console trim back into position, ensuring all clips engage properly without forcing.

Step 7: Install the New Shift Knob

  • Thread the new shift knob onto the short shifter lever by turning it clockwise until snug.
  • If your kit includes a locking mechanism or set screw, tighten it to secure the knob firmly.
  • Double-check that the knob is straight and comfortable to grip.

Step 8: Test the Shift Action

Before driving, test the new shifter’s functionality:

  • Start the vehicle and gently move the shifter through all gear positions.
  • Ensure smooth transitions without sticking or excessive resistance.
  • Take a short test drive to feel the difference in shift throw and verify proper engagement of each gear.

Additional Tips for a Successful Installation

  • Refer to the Manufacturer’s Instructions: Always review the specific instructions provided with your short shifter kit, as designs and installation steps can vary.
  • Keep Fasteners Organized: Use labeled containers to keep bolts and clips organized during disassembly to avoid losing any small parts.
  • Work Methodically: Take your time with trim removal and reinstallation to prevent cracking or breaking plastic components.
  • Lubricate Moving Parts: Proper lubrication is key to smooth shifting and long-lasting performance.
  • Check for Warranty Impact: Installing aftermarket parts may affect your vehicle’s warranty. Verify this with your dealer if concerned.

Common Challenges and How to Overcome Them

Stubborn Shift Knob or Trim Pieces

If the shift knob or trim pieces are difficult to remove, avoid using excessive force. Try gently warming the area with a hairdryer to soften any adhesives or plastic clips. Use trim tools designed for interior panels to minimize damage.

Misaligned Shifter or Hard Shifting

If the shifter feels hard to move or doesn’t align with gears correctly after installation, double-check the linkage connections and mounting bolts. Improperly seated components can cause binding. Adjust as necessary and ensure all fasteners are tightened to spec.

Rattling or Noise After Installation

Rattles can result from loose bolts or worn bushings. Inspect all fasteners and consider adding additional lubrication or replacing bushings if included in your kit.

Maintenance and Care After Installation

To keep your new short shifter performing optimally:

  • Periodically check and tighten all bolts and fasteners.
  • Reapply lubricant to pivot points if shifting becomes stiff.
  • Keep the shift boot clean and free of debris that can cause wear.
  • Inspect the shift knob for signs of wear or loosening and address promptly.
