Warnings

Tools required

Parts

• Shift cable assembly × 1 — Use OEM specification
• Cable grommet (firewall) × 1 — Included with cable or separate
• Cable retaining clips × 2 — Reuse if undamaged

Preparation

1. Park vehicle on level ground and apply parking brake firmly.
2. Place wheel chocks behind rear wheels.
3. Disconnect negative battery cable to prevent accidental starter engagement.
4. Allow engine and exhaust system to cool completely if recently driven.
5. Raise front of vehicle and support securely on jack stands at manufacturer-designated lift points.

Procedure

1. 1

   Remove shifter boot and console trim
   From inside the cabin, carefully pull up on the leather shifter boot to access the base. The boot is retained by friction fit around the console opening. Remove the console side trim panels by locating and removing the fasteners securing them to the center console structure. Check for screws along the bottom edges and any clips along the top edge. Set trim panels aside.
2. 2

   Access shifter assembly mounting
   With the boot removed, locate the shifter assembly base plate. Remove the fasteners securing the shifter assembly to the transmission tunnel. There are typically 4 bolts securing the shifter base plate. Note the position of the shift cable attachment point at the base of the shifter mechanism before disconnection.
3. 3

   Disconnect cable from shifter
   At the base of the shifter, locate the cable attachment point. Compress the cable retaining clip or remove the retaining pin (depending on cable design) to release the cable end from the shifter ball socket. Slide the cable housing out of the mounting bracket on the shifter assembly. Note the exact routing of the cable through the console area and toward the firewall.
4. 4

   Access cable at firewall
   From the engine bay, locate where the shift cable passes through the firewall. The cable grommet is typically located on the driver side of the firewall near the transmission tunnel. Note the cable routing along the firewall and down toward the transmission bell housing area.
5. 5

   Access transmission shift lever
   Working from underneath the vehicle with proper lighting, locate the transmission shift lever on the driver side of the transmission case. Identify the cable attachment point and the cable bracket bolted to the transmission housing. Clear any heat shields or components blocking access to the cable attachment point.
6. 6

   Disconnect cable at transmission
   At the transmission shift lever, remove the retaining clip securing the cable end to the lever arm. Slide the cable end off the lever ball stud. Remove the cable bracket mounting bolts from the transmission housing using the appropriate socket. There are typically 2 bolts securing the cable bracket.

   Remove cable from vehicle
   Working from the engine bay, carefully pull the cable and grommet assembly through the firewall opening. The grommet may require significant force to extract from the firewall opening. From inside the cabin, guide the cable assembly up through the console area and remove it completely from the vehicle. Inspect the firewall grommet opening for damage or rubber deterioration.
8. 8

   Prepare new cable for installation
   Unpack the new shift cable assembly and compare it to the removed cable to verify correct length and end fittings. If the firewall grommet is separate, install it onto the cable housing before installation. Ensure the cable moves smoothly through its full range of motion before installation.
9. 9

   Route new cable through cabin
   From inside the cabin, feed the shifter end of the new cable down through the console area and toward the firewall opening. Route the cable following the same path as the original, avoiding any sharp edges or heat sources. Push the cable and grommet assembly through the firewall opening from inside the cabin until the grommet seats fully in the firewall opening. Ensure the grommet is properly sealed to prevent water or fume intrusion.
10. 10

    Install cable at transmission
    Working from underneath the vehicle, route the cable along the firewall and down to the transmission following the original path. Position the cable bracket on the transmission housing and install the mounting bolts. Torque the cable bracket bolts to specification. Snap the cable end onto the transmission shift lever ball stud and install the retaining clip. Verify the cable is securely attached and the lever moves freely.

11. 11

    Connect cable to shifter assembly
    From inside the cabin, route the cable end through the shifter assembly mounting bracket. Snap the cable end onto the shifter ball socket and install the retaining clip or pin. Verify the cable housing is properly seated in the shifter bracket. Manually move the shifter through all gear positions to check for smooth cable operation and proper engagement.
12. 12

    Adjust cable at transmission
    With an assistant operating the shifter inside the cabin, verify that all gear positions can be selected. At the transmission, check that the shift lever moves to the correct positions corresponding to each gear. If adjustment is needed, loosen the adjustment nut on the cable bracket, position the shifter in the appropriate reference position (typically 3rd gear), align the transmission shift lever to the corresponding detent, then tighten the adjustment nut to specification. Verify all gears can be selected with positive engagement.

    Reinstall shifter assembly and trim
    Reinstall the shifter assembly base plate mounting bolts if they were removed for access. Reinstall the console side trim panels and secure with their original fasteners. Press the shifter boot back into position around the console opening, ensuring it seats properly and appears symmetric.
14. 14

    Final verification and cleanup
    Lower the vehicle from jack stands. Reconnect the negative battery cable. Start the engine (with parking brake applied and clutch depressed) and verify each gear can be selected smoothly through the shift gate. Test drive the vehicle through all gears, checking for smooth shifts, proper gate feel, and no binding or resistance. Verify the shift pattern matches the shift knob markings.

Reassembly

1. Reinstall all console trim panels in reverse order of removal, ensuring all clips and fasteners are properly secured.
2. Verify the shifter boot is properly seated and does not interfere with shifter movement through all gear positions.
3. Double-check that all fasteners under the vehicle are torqued to specification and no tools or parts were left in the work area.

Verification

• With engine running and parking brake applied, shift through all gear positions verifying smooth engagement and proper detent feel.
• Verify the shift lever position corresponds correctly to each gear selection at the transmission.
• Test drive the vehicle and confirm all forward gears and reverse engage properly without grinding or resistance.
• Check that the shifter returns to neutral center position when released between gear selections.
• Inspect under vehicle for proper cable routing with no interference against exhaust, suspension, or sharp edges.
