Governor: Service and Repair

REMOVAL
1. Hoist and support vehicle on safety stands.
2. Mark propeller shaft and axle yoke for assembly reference. Then disconnect and remove shaft.
3. Disconnect parking brake cable at equalizer and disconnect exhaust components as necessary.
4. Support transmission on a suitable lifting device.
5. Remove skid plate and rear transmission mount.
6. Remove extension housing.
7. Loosen but do not remove bolts that hold governor body to park gear.
8. Rotate transmission output shaft until governor weight assembly is accessible.





9. Remove E-clip at end of governor valve shaft (Fig. 108).
10. Remove governor valve and shaft from governor body (Fig. 108).





11. Remove snap rings and spacer that retain governor body and park gear assembly on output shaft (Fig. 109).





12. Remove bolts holding governor body to park gear (Fig. 110).
13. Separate governor from park gear.
14. Pull park gear from rear support.

DISASSEMBLY
1. Remove governor body from transmission.





2. Clean and inspect governor filter (Fig. 111).





3. Remove snap-ring and washer that secure governor weight assembly in body (Fig. 112).
4. Remove governor weight assembly from governor body bore.
5. Slide intermediate and inner weight from outer weight.





6. Position intermediate weight on suitable size socket (Fig. 113).
7. Push inner weight downward with nut driver. Then remove inner weight snap-ring with Snap-Ring Pliers 6823 (Fig. 113).





8. Remove inner weight and spring from intermediate weight (Fig. 114).

CLEANING
Thoroughly clean all the governor parts in a suitable cleaning solution but do not use any type of caustic cleaning agents.








The governor weight components (Fig. 115) and the governor valve (Fig. 116), must slide freely in their bores when clean and dry. Minor surface scratches and burrs can be smoothed with crocus cloth.

INSPECTION
The aluminum governor valve and outer weight have a hard coating on them. Check condition of this coating carefully. Do not reuse either part if the coating is damaged.
Inspect the governor weight spring for distortion. Replace the spring, if distorted, collapsed, or broken. Clean the filter in solvent and dry it with compressed air. Replace the filter, if damaged. Inspect the park gear for chipped or worn gear teeth or damaged ring grooves. Replace the gear, if damaged.
Check the teeth on the park gear for wear or damage. Replace the gear if necessary. Inspect the metal seal rings on the park gear hub. Replace the rings only if severely worn, or broken.

ASSEMBLY

CAUTION: Exercise care when installing the seal rings. They are easily broken if overspread or twisted during installation.

If it was necessary to remove the park gear, inspect the seal rings and bore in rear support. Install new seal rings on park gear hub only if original rings are damaged, or worn. Install ring with interlock ends first and ring with plain ends last. Slip each ring on hub and seat them in grooves. Verify that rear ring ends are securely interlocked before proceeding. If the bore in rear support is damaged, replace the rear support.
1. Lubricate governor components with Mopar ATF +4, Type 9602 transmission fluid before assembly.
2. Clean and inspect governor weights and bores for scoring or wear. Replace the governor body and weights if damaged.
3. Insert spring into intermediate weight.
4. Insert inner weight into intermediate weight and install snap-ring (Fig. 106). Verify snap-ring is fully seated in groove in intermediate weight (Fig. 105).
5. Assemble governor weights into governor body (Fig. 104).
6. Install washer and snap-ring to hold weights in governor body.
7. Install governor body in transmission

INSTALLATION
1. Install park gear into rear support so crown on curved boss is in line with hole through output shaft.
2. Install governor filter in park gear.
3. Slip governor body over output shaft and align port to filter.
4. Install bolts to hold governor body to park gear. Tighten bolts to 11 Nm (95 inch lbs.) torque (Fig. 102).
5. Install governor body-park gear snap-rings and washer on output shaft as follows:
a. Install thin snap-ring first. Then install thrust washer second, and thick snap-ring last (Fig. 101).
b. Verify correct position of snap-rings. Be sure flat side of each snap-ring is toward governor body.
6. Insert governor valve and shaft through governor and install E-clip (Fig. 100).
7. Install extension housing and gasket on transmission. Tighten housing bolts to 32 Nm (24 ft. lbs.).
8. Install rear transmission mount and skid plate.
9. Install speed sensor and speedometer components and connect speed sensor wires.
10. Connect exhaust components and brake cable, if removed.
11. Install propeller shaft.
12. Remove supports and lower vehicle.
13. Check transmission fluid level. Add fluid if necessary.
