CONTROL VALVE BODY DISASSEMBLY/ASSEMBLY

CONTROL VALVE BODY DISASSEMBLY

CAUTION
- Denting or scratching these components will reduce the ability of the transaxle to the shift properly. When handling these components or the valve body that contains them, be careful not to drop or hit them.








1. Disassemble in the order indicated in the table.
2. Neatly arrange the removed parts to avoid confusing the similar parts.

WARNING
- Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eye wear whenever using compressed air.

3. Clean the removed parts with cleaning solvent, then use compressed air to dry them. Use compressed air to clean out all holes and passages.

CONTROL VALVE BODY DISASSEMBLY PROCEDURE





1. Remove manual control valve from the valve body. Remove the two solenoid body component bolts. Remove the solenoid body component.





2. Remove the solenoid gasket from the accumulator body. Discard the solenoid gasket.





3. Remove the three pressure tap plate bolts. Remove the pressure tap plate.





4. Remove the gasket from the accumulator body component. Discard the gasket.





5. Remove the three valve body-to-transfer plate bolts. Remove the detent lever.





6. Remove the three accumulator body component bolts.





7. Remove the accumulator body, separator plate, and gaskets from the valve body component. Discard the gaskets.





8. Remove the valve body, separator plate and gaskets from the transfer plate. Discard the gaskets.

ACCUMULATOR BODY COMPONENT DISASSEMBLY/ASSEMBLY

CAUTION
- Denting or scratching these precisely machined components will reduce the ability of the transaxle to shift properly. When handling these components or the valve body that contains them, be careful not to drop or hit them.

NOTE
- If a valve does not slide out under its own weight, place the valve body open-side down and tap on the valve body lightly with a plastic hammer.





1. Disassemble in the order indicated in the table.

WARNING
- Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eye wear whenever using compressed air.

2. Clean all parts and holes by using compressed air and apply ATF to them immediately before assembly.
3. Assemble in the reverse order of disassembly.

DISASSEMBLY NOTE 2/4 ACCUMULATOR PLUG





1. Remove the 2/4 accumulator plug by using a screwdriver.





2. Remove the 2/4 accumulator plug seal. Discard the seal.

2/4 ACCUMULATOR PLUG SEAL ASSEMBLY NOTE
1. Install a new seal on the 2/4 accumulator plug.
2. Lubricate the plug and install.





CAUTION
- Do not push the plug into the bore beyond flush or damage to the seal will occur.





3. Install the retaining plate by using needle-nosed pliers.
