Valve Body Assembly
VALVE BODY ASSEMBLY
Disassembly Procedure
1. Remove the wire harness clamps.
2. Remove the shift and lockup solenoids.
3. Remove the linear solenoid and the wire harness clamp.
4. Turn the valve body assembly over and remove the four bolts from the lower valve body.
5. Turn the valve body assembly over and remove the five bolts from the upper valve body.
6. Lift off the upper valve body. Remove the check ball.
7. Inspect the shift solenoids and the lockup solenoid. Replace the solenoids if they are not within specifications.
- Using an ohmmeter, check the resistance between the solenoid terminal and the solenoid body. The standard resistance for shift solenoids is 12 - 16 ohms. The standard resistance for the lockup solenoid is 11 - 15 ohms.
- Apply battery voltage to the solenoids. An operation noise should be heard.
8. Inspect the linear solenoid. If the solenoid is not within specifications, replace it.
- Using an ohmmeter, check the resistance between the solenoid terminals. The standard resistance is -3.6 ohms.
Notice: Discard the valve body gaskets.
9. Remove the upper valve body gasket, the upper valve body separator plate and the center valve body gasket.
10. Remove the oil strainers from the center valve body.
11. Remove the three bolts from the lower valve body.
Notice: Hold the gaskets and separator plate to the center valve body and remove as an assembly.
12. Turn the valve body over and remove the remaining bolt. Separate the center valve body from the lower valve body.
Notice: Discard the valve body gaskets.
13. Separate the valve body gaskets and separator plate.
14. Remove the bypass valve, the check valve, springs and the check balls from the center valve body.
15. Remove the check valve, the pressure relief valve, springs and check balls from the lower valve body.
Assembly Procedure
Notice: Coat the valves and springs with Texaco 1854 automatic transmission fluid prior to assembly.
1. Install the bypass valve, the check valve, springs and the check balls in the center valve body.
2. Install the check valve, the pressure relief valve, springs and check balls in the lower valve body.
3. Install a new center valve body gasket, a center valve body separator plate and a new lower valve body gasket on the center valve body.
- Place the center valve body onto the lower valve body. Hold the center valve body, gaskets and plate securely so they do not separate.
4. Install the three bolts in the lower valve body. Do not tighten the bolts at this time.
5. Turn the valve body over and install the bolt. Do not tighten the bolt at this time.
Notice: Coat the oil strainers with Texaco 1854 automatic transmission fluid prior to assembly.
6. Install the oil strainers into the center valve body.
7. Install the check ball in the upper valve body.
8. Install a new center valve body gasket, a center valve body separator plate and a new upper valve body gasket.
- Place the upper valve body onto the center valve body. Hold the upper valve body, gaskets and plate securely so they do not separate.
9. Install the five bolts in the upper valve body. Do not tighten at this time.
- Three 50 mm (1.9 inch) bolts
- One 45 mm (1.8 inch) bolt
- One 65 mm (2.5 inch) bolt
10. Turn the valve body over and install the four bolts. Do not tighten the bolt at this time.
- 65 mm (2.5 inch) bolts
Notice: Apply Texaco 1854 automatic transmission fluid to the solenoid O-ring.
11. Install the shift and lockup solenoids.
Tighten
Tighten the solenoid bolts to 6 - 7 Nm (52 - 65 inch lbs.).
Notice: Apply Texaco 1854 automatic transmission fluid to the solenoid O-ring.
12. Install the linear solenoid and the wire harness clamp.
Tighten
Tighten the solenoid bolt to 6 - 7 Nm (52 - 65 inch lbs.).
Notice: Tighten the bolts evenly and gradually.
13. Tighten the 14 upper and lower valve body bolts.
Tighten
Tighten the bolts to 6 - 7 Nm (52 - 65 inch lbs.).
Notice: Coat the manual valve with Texaco 1854 automatic transmission fluid prior to assembly.
14. Install the manual valve.
