Tools required

Parts

• Shift linkage assembly × 1 — A2212670637 or Use OEM specification
• Linkage bushings × 2 — A2212670837
• Shift rod clips × 2 — Use OEM specification

Preparation

1. Park vehicle on level surface and set parking brake.
2. Place wheel chocks behind rear wheels.
3. Raise front of vehicle and support on jack stands at designated jacking points.
4. Remove engine undertray if equipped (varies by model year).
5. Allow engine and transmission to cool completely if recently driven.

Procedure

1. 1

   Access shift linkage from below
   Position yourself under the vehicle near the transmission tunnel. Locate the shift linkage running from the cabin firewall to the transmission selector shaft on the driver's side of the transmission. The linkage connects at two points: the selector lever inside the cabin and the transmission range selector shaft.
2. 2

   Disconnect linkage at transmission end
   Locate the shift rod connection to the transmission selector shaft. Remove the retaining clip securing the ball socket to the selector shaft ball stud. Use a small pry bar or ball joint separator if necessary to pop the ball socket off the stud. Note the orientation of the linkage for reassembly.
   ℹ️Mark the position of the linkage adjustment if replacing with same part to maintain approximate adjustment.
3. 3

   Remove linkage pivot bolts
   Locate the linkage pivot bracket mounted to the transmission or chassis. Remove the pivot bolts securing the linkage support bracket. There are typically two bolts holding the intermediate pivot point. Support the linkage as you remove these bolts to prevent it from dropping.
   Torque spec

   Pivot Bolts12 Nm (9 lb-ft)
4. 4

   Access cabin side connection
   From inside the cabin, remove the lower center console trim panels to access the shift lever mechanism. Remove trim screws and carefully pull panels away. You may need to remove the cupholder assembly for full access. Locate where the linkage rod connects to the shift lever assembly.
   Torque spec

   Cover Screws15 Nm (11 lb-ft)
5. 5

   Disconnect cabin side linkage
   Remove the retaining clip at the shift lever ball socket connection. Disconnect the linkage rod from the shift lever mechanism. If replacing bushings only, note which bushings show wear (typically the transmission end wears first).
6. 6

   Remove shift linkage assembly
   Return to underneath the vehicle and carefully guide the shift linkage assembly out through the access area. The linkage may need to be rotated or angled to clear surrounding components. Inspect the removed linkage for worn bushings, damaged ball sockets, or bent rods.
7. 7

   Prepare new linkage or replace bushings
   If installing a new linkage, transfer any reusable hardware. If only replacing bushings, press out old bushings using appropriate tool or socket, and press in new bushings ensuring they are fully seated. Apply a small amount of white grease to all ball socket joints and pivot points.
8. 8

   Install linkage assembly
   Route the shift linkage assembly from underneath the vehicle up to the cabin area, following the original path. Ensure all grommets and seals are in place where the linkage passes through the firewall. Connect the cabin side first by snapping the ball socket onto the shift lever ball stud and installing the retaining clip.
9. 9

   Install pivot bracket
   Position the linkage support bracket at the intermediate pivot point. Install and torque the pivot bolts to specification. Ensure the linkage moves freely through its full range of motion without binding.
   Torque spec

   Pivot Bolts12 Nm (9 lb-ft)
10. 10

    Connect transmission end
    With the transmission selector shaft in Park position (fully rearward), connect the linkage ball socket to the transmission selector shaft ball stud. Install the retaining clip, ensuring it is fully seated and locks the connection securely.
11. 11

    Adjust linkage alignment
    Verify that with the cabin shift lever in Park, the transmission selector shaft is in the full Park detent. If adjustment is needed, loosen the linkage adjustment bolts at the transmission end, align properly, and retighten. The adjustment point is typically at the transmission end ball socket mounting.
    ⚠Proper adjustment is critical for Park pawl engagement and preventing rollaway.

    Reinstall interior trim
    Reinstall all center console trim panels, cupholder assembly, and any removed interior components. Secure all trim screws to specification to prevent rattles.

    Cover Screws15 Nm (11 lb-ft)

Reassembly

1. Reinstall engine undertray if removed.
2. Lower vehicle from jack stands.
3. Verify all tools and parts have been removed from under vehicle and cabin.

Verification

• With engine off, verify shift lever moves smoothly through all gear positions (P-R-N-D-S) with appropriate detent feel.
• Start engine with foot on brake and verify transmission engages each gear properly. Listen for any unusual noises.
• Verify that key can only be removed in Park position and steering wheel locks when key is removed.
• Test that vehicle will not start in any gear position except Park and Neutral (neutral safety switch function).
• On level ground, verify vehicle does not roll when placed in Park with parking brake released.
• Test drive vehicle and verify smooth gear selection and no delay in engagement.
• Verify transmission gear display in instrument cluster matches actual gear selector position for all positions.
