CLEAN
- Control valve assembly thoroughly in clean solvent.
A. Move the valves with a pick or small screwdriver to dislodge any dirt or debris that may have accumulated.
B. Air dry.

REMOVE OR DISCONNECT

IMPORTANT
- Some valves are under pressure - cover the bores while removing roll pins and retainer clips.
- Valves, springs and bushings must be laid out on a clean surface in the exact sequence they are removed.

1. Pressure control solenoid retainer bolt (364) retainer (378) and solenoid.
2. Bore plug retainer clip (395), bore plug (376) and valve train (374 and 375).
3. 2-3 shift solenoid retainer (379), solenoid (367) and valve train (368 and 369).
4. 1-2 shift solenoid retainer (379), solenoid (367) and valve train (365 and 366).
5. Accumulator valve train retainer pin (360), bore plug (373) and valve train (370 and 371).
6. Forward accumulator cover bolts (364) and cover (363).
7. Forward accumulator spring (356), piston (354) and pin (355).
8. Lo overrun valve spring (362) and valve (361).
9. Retainer pin (360), bore plug (359) and forward abuse valve train (357 and 358).
10. Manual valve (340).
11. 3-2 control solenoid retainer clip (379) and solenoid (394).
12. Bore plug retainer (395), bore plug (381) and 3-2 control valve train (391 - 393).
13. 3-2 downshift bore plug retainer (395), bore plug (381) and valve train (389 - 390).
14. Reverse abuse bore plug retainer pin (360), bore plug (359) and valve train (387 - 388).
15. 3-4 shift valve bore plug retainer (395), bore plug (381) and valve train (385 - 386).
16. 3-4 relay bore plug retainer (395), bore plug (381) and valve train (382 - 384).
17. [1][2]Torque converter clutch signal valve bore plug retainer (395), bore plug (381) and valve (380).

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
- Inter connected oil passages
- Damaged machined surfaces

ASSEMBLE
- Control valve assembly (350) exactly as shown.
- Notice the position of the valve lands and bushing passages.
- Position the pressure control solenoid so the connector tabs face outward.

NOTICE: TCC PWM solenoid (396) cannot be installed until TCC solenoid has been installed and torqued to proper specifications.

INSTALL OR CONNECT
1. Checkballs into the valve body assembly (350).
- Retain with Transjell TM J 36850 or equivalent.
2. Valve body assembly (350).
- Connect the manual valve link (89) to the inside detent lever (88).
- Be careful not to damage screens when installing the valve body assembly.
3. Wiring harness (66), manual spring assembly (63), pressure switch assembly(69), dipstick, stop bracket (93) and all remaining valve body bolts.

NOTICE: Torque valve body bolts in a spiral pattern starting from the center. If bolts are torqued at random, valve bores may be distorted and inhibit valve operation.

4. TCC solenoid (66) and bolts (68).

TIGHTEN
- Bolts to 11 Nm (8 lb. ft.).

5. TCC PWM solenoid (396), and retainer clip (379).

INSTALL OR CONNECT
- Wiring harness connections to electrical components.
- To correctly hook up the wires, see the wiring diagrams.
- The pressure control solenoid (377) has two different colored connectors. The black connector should be installed on the tab farthest from the valve body.

INSTALL OR CONNECT
1. Parking bracket (86).

TIGHTEN
- Bolts to 31 Nm (23 lb. ft.).

2. The 1-2 accumulator piston seal (55) onto the 1-2 accumulator piston (56).
3. The 1-2 accumulator spring (54) and 1-2 accumulator inner spring (54A) onto the piston (56).
4. The 1-2 accumulator piston (56) into the 1-2 accumulator cover and pin assembly (57).
- The three legs on the piston must face away from the case when installed.
5. The 1-2 accumulator cover and pin assembly (57) onto the case.

TIGHTEN
- Torque to 11 Nm (8 lb. ft.).
