Special Tool(s)

Removal
1. Raise and support the vehicle.
2. Remove the exhaust heat shield.

3. CAUTION: Index-mark (color paint) the bolts, washers, nuts, and the flex coupling to the transmission flange and the pinion flange to assure assembly in the exact same location. Components not assembled in their original locations can cause driveshaft imbalance.

CAUTION: Do not remove the bolts retaining the flex coupling to the driveshaft.





Index-mark the front driveshaft companion flange. Remove the three nuts, washers and bolts.





4. Slide the front shaft assembly rearward and support.

5. WARNING: Secure the transmission to the transmission jack with a safety chain. Failure to follow these instructions may result in personal injury.

Support the transmission with a transmission jack.





6. Remove the transmission mount and lower the transmission enough to gain access to the digital TR sensor.





7. Disconnect the shift cable.





8. Remove and discard the tie strap from the digital TR sensor connector boot.





9. Slide the rubber boot back and disconnect the digital TR sensor connector.





10. Remove the digital TR sensor.

Installation

1. CAUTION: The digital transmission range sensor must fit flush against the boss on the case to prevent damage to the sensor.





Install the digital TR sensor and loosely install the screws.

2. CAUTION: Tightening one screw before tightening the other may cause the sensor to bind or become damaged.

NOTE: The manual lever must be in the NEUTRAL position.





Using the special tool, align the digital TR sensor and tighten the screws in an alternating sequence.





3. Reconnect the digital TR sensor connector.





4. Slide the boot over the digital TR sensor connector and install a new tie strap.





5. Connect the shift cable.





6. Install the rear transmission support and remove the transmission jack.
7. Verify that the shift cable is adjusted correctly.

8. CAUTION: Align the index marks or driveshaft imbalance can occur.





Align index marks made during removal and position the driveshaft on the transmission flange.

9. CAUTION: Install the bolts, washers and nuts in their original positions or driveshaft imbalance can occur. Install the driveshaft flex coupling bolts with the head of the bolt seated against the flange, and the nuts seated against the flex coupling.





Install the bolts, washers and nuts. Coat the nut and bolt threads with threadlock sealer.
10. Install the exhaust heat shield.
11. Lower the vehicle.
