Step-By-Step Installation Process

1. Lift and Secure the Vehicle

Using a hydraulic jack, raise the front of your Acura TLX Type S and place it securely on jack stands. Never work under a vehicle supported only by a jack. Confirm the vehicle is stable before proceeding.

2. Remove the Driveshaft and Transmission Components

Begin by removing any components obstructing access to the transmission. This typically includes:

  • Disconnecting the driveshaft from the rear differential and transmission.
  • Removing exhaust hangers or heat shields if necessary for clearance.
  • Detaching the shifter linkage and electrical connectors from the transmission.
  • Removing the starter motor to gain better access to transmission bolts.

After clearing these parts, unbolt the transmission mounts and the bolts securing the transmission bellhousing to the engine block.

3. Lower the Transmission

With help or using a transmission jack, carefully lower the transmission away from the engine. Ensure it clears the clutch assembly and other components without damage. Set the transmission aside in a safe, clean area.

4. Remove the Old Clutch Assembly

Inspect the clutch assembly components, then proceed to remove the pressure plate bolts in a star pattern to avoid warping. Remove the pressure plate and clutch disc from the flywheel.

Check the flywheel condition thoroughly. Look for cracks, hot spots, or uneven wear. If the flywheel surface is damaged or glazed, it should be resurfaced by a professional or replaced entirely to ensure proper clutch engagement.

5. Clean and Prepare the Flywheel

Use brake cleaner or a suitable degreaser to clean the flywheel surface thoroughly. Avoid contaminating the surface with grease or oils. Allow it to dry completely before proceeding.

6. Install the New Clutch Kit

Using the clutch alignment tool, position the new clutch disc centered on the flywheel. Carefully place the pressure plate over the clutch disc, aligning it with the dowel pins or bolt holes on the flywheel.

Hand-tighten the pressure plate bolts in a criss-cross pattern to evenly distribute pressure. Then, using a torque wrench, tighten the bolts to the manufacturer’s specified torque values. This prevents warping and ensures consistent clutch engagement.

7. Replace the Release Bearing and Inspect Components

Replace the release (throw-out) bearing with the new one included in your clutch kit. Lubricate it lightly with high-temperature grease if recommended by the manufacturer. Also, inspect the pilot bearing or bushing inside the flywheel and replace it if worn.

8. Reinstall the Transmission

Carefully align and raise the transmission back into position, ensuring the input shaft slides smoothly into the clutch disc spline. Avoid forcing the transmission, as misalignment can damage the clutch or transmission components.

Once aligned, secure the transmission bellhousing bolts, tightening them in a specified sequence and torque as per the service manual.

Reattach the starter motor, shifter linkage, electrical connectors, and driveshaft components you removed earlier.

9. Refill Transmission Fluid and Reconnect Battery

If the transmission fluid was drained or contaminated during the process, refill it with the correct type and quantity specified in your vehicle’s manual. Proper fluid levels are essential for smooth transmission operation and longevity.
