Warnings
⚠Ensure vehicle is in PARK and parking brake is fully engaged before beginning work.
⚠If engine was recently running, allow exhaust components to cool before working underneath vehicle.
ℹ️Improper shift cable adjustment will result in incorrect gear position indication and potential transmission damage.
⚠️Never work under a vehicle supported only by a jack. Always use jack stands rated for the vehicle weight.

Parts
- Transmission shift cable assembly × 1 — Use OEM specification
- Cable grommets (if damaged) × 1 — Use OEM specification
- Retaining clips (if broken) × 2 — Use OEM specification
Preparation
- Park vehicle on level surface and engage parking brake firmly
- Place wheel chocks behind rear wheels
- Ensure transmission is in PARK position
- Raise front of vehicle and secure on jack stands rated for vehicle weight
- Verify vehicle is stable before working underneath
- Allow hot exhaust components to cool if engine was recently running
Procedure
- 1Remove center console trimWorking inside the cab, remove the center console trim panel surrounding the shift lever. Use trim panel removal tools to carefully release the retaining clips. Remove any screws securing the upper console panel and lift away to expose the shift lever base and cable connection.
- 2Disconnect shift cable at shifterAt the shift lever assembly, locate the shift cable end. Press the locking tab on the cable bushing and use a flathead screwdriver to pry the cable end off the shift lever ball stud. Note the orientation and routing of the cable for reinstallation. Remove the cable adjustment nut at the shifter bracket if equipped.Torque specAdjustment Nut10 Nm (7 lb-ft)
- 3Remove shifter cable bracketLocate the cable bracket mounting bolts at the shifter base. Remove the cable bracket bolts using a socket wrench. Carefully pull the cable housing from the bracket, noting any grommets or retaining clips that must be transferred to the new cable.Torque specCable Bracket Bolts15 Nm (11 lb-ft)
- 4Remove cable firewall grommetWorking from inside the cab, trace the cable toward the firewall. Locate where the cable passes through the firewall into the engine compartment. From inside the cab, carefully push the cable grommet through the firewall opening. Note the grommet orientation for reinstallation.
- 5Access transmission shift leverWorking underneath the vehicle, locate the transmission shift lever on the driver's side of the transmission. The lever is typically positioned near the transmission pan on the 68RFE transmission. Clean the area around the cable connection to ensure proper visibility.
- 6Disconnect cable at transmissionAt the transmission shift lever, press the locking tab on the cable end bushing and remove the cable from the transmission lever ball stud. Use needle nose pliers if necessary to release stubborn clips. Remove any retaining clips securing the cable housing to the transmission bracket.
- 7Remove cable routing bracketsTrace the cable from the transmission forward to the firewall, noting all routing brackets and supports. Remove any mounting bolts or clips securing the cable to the frame, transmission crossmember, or other mounting points. Keep track of all hardware for reinstallation.Torque specMounting Bolts82 Nm (61 lb-ft)
- 8Remove old cableCarefully pull the cable through the firewall from the engine compartment side, ensuring it clears all routing points and does not catch on any components. Inspect the firewall grommet and replace if cracked or damaged.
- 9Install new cable through firewallFrom inside the cab, feed the new shift cable through the firewall opening. Ensure the firewall grommet is properly seated in the firewall hole to prevent water and air leakage. The cable should pass through smoothly without binding.
- 10Route and secure cable underneathWorking underneath the vehicle, route the new cable along the factory path, following the same routing as the original cable. Secure the cable to all mounting brackets and supports using the appropriate hardware. Ensure the cable has adequate clearance from exhaust components, driveshaft, and suspension parts. Verify no sharp bends or kinks exist in the cable routing.⚠Ensure cable maintains minimum 2 inches clearance from exhaust components to prevent heat damage.Torque specMounting Bolts82 Nm (61 lb-ft)
- 11Connect cable to transmission leverAt the transmission shift lever, snap the cable end bushing onto the transmission lever ball stud until it clicks into place. Tug firmly on the cable to verify it is securely attached. Install any cable housing retaining clips to the transmission bracket.
- 12Install cable at shifter bracketWorking inside the cab, insert the cable housing into the shifter bracket until it seats fully. Install the cable bracket bolts and tighten to specification. Ensure the cable moves freely through the bracket without binding.Torque specCable Bracket Bolts15 Nm (11 lb-ft)
- 13Connect cable to shift leverSnap the cable end bushing onto the shift lever ball stud until it locks into place. Verify the connection is secure by pulling on the cable. The bushing should not separate from the ball stud.
- 14Adjust shift cableWith the transmission in PARK (verify at transmission lever underneath vehicle), adjust the cable at the shifter bracket using the adjustment nut. The shifter should be in the PARK position with the cable properly tensioned. Adjust until there is minimal free play but the cable is not under tension. Tighten the adjustment nut to specification once proper adjustment is achieved.ℹ️Proper adjustment is critical - shifter must align precisely with transmission position to ensure accurate gear selection and PARK safety function.Torque specAdjustment Nut10 Nm (7 lb-ft)
- 15Verify operation and reinstall trimBefore reinstalling console trim, cycle the shifter through all gear positions (P-R-N-D-3-2-1) while observing the transmission shift lever underneath the vehicle. Each detent position should correspond to the proper transmission position. Verify positive engagement in PARK and that the key can be removed only in PARK. Once verified, reinstall the center console trim panels and secure all fasteners.
Reassembly
- Reinstall center console trim panels ensuring all clips are fully engaged
- Lower vehicle from jack stands
- Remove wheel chocks
Verification
- Start engine and verify shifter moves smoothly through all gear positions with engine running
- Verify transmission engages each gear properly (P-R-N-D) with corresponding instrument cluster indicator
- Confirm vehicle will not start in any gear position except PARK and NEUTRAL
- Verify ignition key can only be removed when shifter is in PARK position
- Test that vehicle rolls freely in NEUTRAL and is locked in PARK on an incline
- Check underneath vehicle for proper cable routing with no interference or contact with hot/moving components
- Perform a test drive verifying smooth shifts and proper gear engagement in all drive ranges
