Shift Solenoid: Service and Repair
REMOVE OR DISCONNECT1. Negative (-) battery cable.
2. Raise and suitably support vehicle.
3. Place index mark (reference mark) on the propeller shaft pinion flange and the front differential pinion flange of the transfer case to front differential propeller shaft (four-wheel drive models).
4. Four bolts, four nuts and separate pinion flange yoke from front differential pinion flange (four-wheel drive models).
- Position and support transfer case to front differential propeller shaft away from transmission fluid pan.
Important: Removing propeller shaft from transfer case will result in fluid loss (four-wheel drive models).
5. Place a drain pan or suitable container under transmission drain plug.
6. Drain plug allowing the transmission fluid pan to drain.
7. Fourteen transmission fluid pan bolts and transmission fluid pan and gasket from transmission.
8. Three fluid pipes in the following order "A", "C" and "D".
9. Electrical connector from shift solenoid assembly.
10. Two bolts and brake applying cover and brake applying cover gasket from transmission body.
11. Three bolts, shift solenoid assembly and shift solenoid assembly gasket from lower valve body.
Inspect
- For shift solenoid assembly inspection and diagnosis procedures, refer to AUTOMATIC TRANSMISSION DIAGNOSIS, DRIVEABILITY AND EMISSIONS, and for a complete schematic of the shift solenoid assembly system, refer to ELECTRICAL DIAGNOSIS.
INSTALL OR CONNECT
1. New shift solenoid assembly gasket and shift solenoid assembly to lower valve body; secure with three bolts.
- Tighten shift solenoid assembly bolts to 10 Nm (89 inch lbs.).
2. Electrical connector to shift solenoid assembly.
3. New brake applying cover gasket and brake applying cover onto transmission body; secure with two bolts.
- Tighten brake applying cover bolts to 10 Nm (89 inch lbs.).
4. Apply a thin coat of automatic transmission fluid to the fluid pipe O-rings.
5. Four fluid pipes in the following order "D", "C" and then "A".
6. New transmission fluid pan gasket and transmission fluid pan to transmission; secure with fourteen bolts.
Important: When installing transmission pan, ensure filler tube connects properly.
- Tighten transmission fluid pan bolts to 5 Nm (44 inch lbs.).
7. Transmission drain plug into transmission.
- Tighten transmission drain plug to 16 Nm (12 ft. lbs.).
8. Front propeller shaft into vehicle aligning index marks made during front propeller shaft removal; secure with four bolts and four nuts (four-wheel drive models).
- Tighten front propeller shaft bolts and nuts to 50 Nm (37 ft. lbs.).
9. Lower vehicle.
10. Negative (-) battery cable.
11. Refill transmission as necessary:
A. Place vehicle on a level surface.
B. Remove fluid level indicator.
C. Add approximately 1.5 liters (1.6 qts.) of Dexron(R)-III automatic transmission fluid into fluid filler tube.
D. Install fluid level indicator into fluid filler tube.
E. Apply parking brake and block vehicle wheels.
F. With selector lever in "P" position, start engine. DO NOT race engine.
G. Run engine at idle and move selector lever through each range and return to the "P" position.
H. With engine running at idle, remove fluid level indicator from filler tube and wipe indicator off.
I. Reinsert fluid level indicator into filler tube making sure it is seated in its original position.
J. Remove the indicator and check the fluid level. The level should be between the "FULL HOT" and "LOW HOT" marks. If the level is below the "LOW HOT" mark, add fluid to bring the level to the "FULL HOT" mark. Bringing the fluid level from the "LOW HOT " mark to the " FULL HOT" mark requires 0.3 liters (0.3 qts.) of fluid. Use Dexron(R)-III automatic transmission fluid.
K. Conduct a road test and check transmission level. Refer to CHECKING FLUID LEVEL (NORMAL OPERATING TEMPERATURE).
