Control Valve Body
CleanPart 1 Of 2:
Part 2 Of 2:
- Control valve assembly thoroughly in clean solvent.
- Move valves with a pick or a small screwdriver to dislodge any dirt or debris that may have accumulated.
- Air dry.
CAUTION: Some valves are under pressure. Cover the bores while removing the roll pins or personal injury could result.
Important: Valves, springs, and bushings must be laid out on a clean surface in the exact sequence they were removed and as shown.
DISASSEMBLE
1. Pressure control solenoid retainer bolt, retainer, and the solenoid.
2. Bore plug retainer clip, bore plug, and the valve train.
3. 2-3 shift solenoid retainer, solenoid, and the valve train.
4. 1-2 shift solenoid retainer, solenoid, and the valve train.
5. Accumulator valve train retainer pin, bore plug, and the valve train.
6. Forward accumulator cover bolts and cover.
7. Forward accumulator spring, piston, and the pin.
8. Low overrun valve spring and the valve.
9. Retainer pin, bore plug, and forward abuse valve train.
10. Manual valve.
11. 3-2 control solenoid retainer clip and the solenoid.
12. Bore plug retainer, bore plug, and the 3-2 control valve train.
13. 3-2 downshift bore plug retainer, bore plug, and the valve train.
14. Reverse abuse bore plug retainer pin, bore plug, and the valve train.
15. 3-4 shift valve bore plug retainer, bore plug, and the valve train.
16. Torque converter clutch signal valve bore plug retainer, bore plug, and the valve.
Clean
- All valves, springs, bushings, and control valve body in clean solvent.
- Dry using compressed air.
Inspect
- All valves and bushings for:
- Porosity.
- Scoring.
- Nicks.
- Scratches.
- Springs for damaged or distorted coils.
- Valve body casting for:
- Porosity.
- Cracks.
- Interconnected oil passages.
- Damaged machined surfaces.
ASSEMBLE
- Control valve assembly exactly as shown.
- Notice the position of the valve lands and the bushing passages.
- Position the pressure control solenoid so the connector tabs face outward.
INSTALL OR CONNECT
1. Checkballs into the valve body assembly.
- Retain with Transjel(R) J 36850 or equivalent.
2. Valve body assembly.
- Connect the manual valve link to the inside detent lever.
- Be careful not to damage the screens when installing the valve body assembly.
3. Wiring harness, manual spring assembly, pressure switch assembly, and all of the remaining valve body bolts.
NOTICE: Tighten the valve body bolts In a spiral pattern starting from the center. If the bolts are tightened at random, the valve bores may be distorted and inhibit the valve operation.
4. TCC solenoid and the bolts.
- Tighten bolts to 11 Nm (97 inch lbs.).
INSTALL OR CONNECT
1. Wiring harness connections to the electrical components.
- The pressure control solenoid has two different colored connectors. The black connector should be installed on the tab farthest from the valve body.
2. Parking bracket.
- Tighten bolts to 31 Nm (23 ft. lbs.).
3. 1-2 accumulator piston seal onto the 1-2 accumulator piston.
4. 1-2 accumulator piston into the 1-2 accumulator cover and pin assembly.
- The three legs on the piston must face toward the case when installed.
5. 1-2 accumulator spring on the piston.
6. 1-2 accumulator cover, bolts, and the pin assembly onto the case.
- Tighten bolts to 11 Nm (97 inch lbs.).
7. New filter and gasket, pan bolts and new oil.
8. Lower the vehicle.
9. Negative battery cable.
Adjust
- New transmission oil.
