Tools required

Parts

• Shift linkage assembly (if replacing) × 1 — Use OEM specification
• Shift linkage bushings × 1 — Use OEM specification
• Shift rod clips × 2 — Use OEM specification

Preparation

1. Park vehicle on level surface and apply parking brake
2. Place wheel chocks behind rear wheels
3. Place transmission in neutral position
4. Allow exhaust system to cool completely if vehicle was recently driven
5. Take multiple reference photos of shift linkage from various angles under vehicle
6. Apply penetrating oil to all visible linkage connection points and allow to soak

Procedure

1. 1

   Raise and support vehicle
   Raise the front of the vehicle using a floor jack at the front jacking point. Secure with jack stands under the frame rails. The vehicle should be raised high enough to provide comfortable working access underneath. Ensure the vehicle is stable before proceeding.
2. 2

   Access shift linkage from interior
   From inside the vehicle, remove the shift knob by rotating counterclockwise. Remove the shift boot by pulling upward to expose the shift lever base. This provides access to the upper linkage connection point at the shifter assembly.
3. 3

   Disconnect upper shift linkage connection
   Locate the shift rod connection at the base of the shifter assembly. Remove the retaining clip securing the shift rod to the shifter ball socket using needle-nose pliers. Note the orientation of the clip for reinstallation. Disconnect the shift rod from the shifter by pulling straight up while supporting the linkage from below.
4. 4

   Access linkage from underneath vehicle
   Move underneath the vehicle with adequate lighting. Locate the shift linkage assembly running from the transmission tunnel area rearward to the transmission. The linkage consists of rods, pivots, and connection points between the shifter and the transmission shift lever.
5. 5

   Disconnect linkage at transmission shift lever
   Locate the connection point where the shift linkage attaches to the transmission shift lever on the driver side of the transmission. Remove the retaining clip using needle-nose pliers or a small flathead screwdriver. Disconnect the linkage rod from the transmission shift lever ball stud. Note the exact orientation and position of all components.
6. 6

   Remove intermediate linkage support bracket
   Locate the intermediate support bracket that secures the shift linkage to the transmission tunnel or crossmember. Remove the 2 bolts securing this bracket using a 13mm socket. Support the linkage assembly as you remove the bracket to prevent it from falling.
7. 7

   Remove shift linkage assembly
   Carefully guide the shift linkage assembly downward and rearward from underneath the vehicle. The assembly may need to be rotated or angled to clear the transmission tunnel, exhaust components, and crossmember. Inspect all pivot points, bushings, and rod ends for wear, cracks, or damage.
8. 8

   Inspect and prepare replacement linkage
   If replacing the linkage, transfer any reusable components from the old assembly to the new one if applicable. If repairing, replace all worn bushings and damaged clips. Ensure all pivot points move freely without binding. Compare the new or repaired linkage to your reference photos to confirm proper configuration.
9. 9

   Install shift linkage assembly
   Guide the shift linkage assembly into position from underneath the vehicle, routing it carefully between the transmission tunnel, exhaust components, and crossmember. Align the assembly so that both the upper shifter connection point and the transmission lever connection point are accessible. Use your reference photos to ensure correct routing and orientation.
10. 10

    Install intermediate support bracket
    Position the intermediate support bracket and align the linkage assembly with the bracket mounting holes. Install the 2 mounting bolts and tighten using a 13mm socket. Ensure the linkage moves freely through its full range of motion without binding on the bracket.
11. 11

    Connect linkage to transmission shift lever
    Attach the shift rod to the transmission shift lever ball stud, ensuring the connection is fully seated. Install a new retaining clip to secure the connection. Verify the clip is properly engaged by attempting to pull the rod off the ball stud.
12. 12

    Connect upper linkage to shifter assembly
    From inside the vehicle, align the shift rod with the shifter ball socket at the base of the shift lever. Push the rod firmly onto the ball socket until fully seated. Install a new retaining clip to secure the connection. Verify the connection is secure by pulling on the shift rod.
13. 13

    Adjust linkage alignment
    With all connections secured, verify that the transmission is in neutral. Move the shifter through all gear positions, checking for smooth engagement without binding or excessive play. If adjustment is needed, loosen the adjustment bolt at the transmission shift lever connection point using a 15mm wrench, align the linkage for optimal shift feel, and retighten.
14. 14

    Reinstall interior components
    Reinstall the shift boot by pressing it into position around the shifter base. Thread the shift knob onto the shifter and tighten by rotating clockwise until snug. Ensure the knob is properly aligned.
15. 15

    Lower vehicle and final inspection
    Remove jack stands and carefully lower the vehicle to the ground. Test shift lever operation through all gear positions with the engine off, verifying smooth engagement and proper gate feel. Check that reverse lockout functions properly.

Reassembly

1. Ensure all retaining clips are new and properly seated to prevent linkage separation during operation
2. Verify linkage does not contact exhaust components or other moving parts throughout its full range of motion
3. Apply a small amount of lithium grease to ball socket connections to ensure smooth operation

Verification

• Start engine and test shift operation through all gears with clutch depressed, verifying smooth engagement without grinding
• Verify correct gear position alignment between shifter position and actual transmission gear
• Test reverse lockout mechanism functions properly
• Drive vehicle and verify all gears engage smoothly under load without popping out or difficulty shifting
• Check for any abnormal noises or vibrations from the linkage area during shifting and driving
