Main control valves

Withdrawal

1. Remove the transmission fluid housing. For more information, refer to the Transmission Fluid Carter section found in this section.

2. Disconnect the transmission fluid temperature sensor connector (TFT).



3. Remove the transmission fluid filter.



4.

NOTE: Note the location of the main control wiring harness connectors as they can only be connected in the same positions. The color letters of the connectors are molded on the solenoid valve block.

Remove the ground wire bolt. Disconnect the plug connectors and remove the wiring harness of the main control unit.

• 1. Solenoid valve SSC; Color N (neutral white color).
• 2. Solenoid valve SSE: Color G (green)
• 3. SSD solenoid valve: Color L (blue)
• 4. EPC solenoid valve: Color B (black)
• 5. Solenoid valve SSA: Color N (neutral (grayish))
• 6. Solenoid valve SSB: Color B (black)

5.

NOTE: Mark the position of the two long bolts.

Remove the main control valve block and accumulators.



6.

NOTE: Each drive is equipped with two springs. All four springs are different sizes.

NOTE: To facilitate assembly, note the size and location of the accumulator springs.

Remove pistons and accumulator springs.

Installation

1.

NOTE: Thin long springs - for neutral and range accumulators («D»).

Install pistons and accumulator springs.

• 1. Accumulator 1 and 2.
• 2. Drive N and D.

2.

CAUTION: Make sure the manual valve is located on the manual valve shift lever.

NOTE: Do not fully tighten the main control valve block bolts at this stage.

Install the main control valve block.



3. Tighten the main control valve block bolts.

• Tighten the bolts in the sequence shown.

4.

NOTE: Plug connectors must be mated in their original position as noted during disassembly. The color letters of the connectors are molded on the solenoid valve block.

Install the main control valve harness, connect the plug connectors, and install the ground wire bolt.

• 1. Solenoid valve SSC; Color N (neutral white color).
• 2. Solenoid valve SSE: Color G (green)
• 3. SSD solenoid valve: Color L (blue)
• 4. EPC solenoid valve: Color B (black)
• 5. Solenoid valve SSA: Color N (neutral (grayish))
• 6. Solenoid valve SSB: Color B (black)

5. Install the transmission fluid filter.




6. Connect the plug connector of the TFT sensor.



7. Install the transmission fluid housing. For more information, refer to the Transmission Fluid Carter section found in this section.
