Pressure Regulating Solenoid: Service and Repair

Solenoid Body Assembly

Material:











Removal

NOTE: The PCM must be updated with a new solenoid body strategy data file and solenoid body ID anytime a new solenoid body is installed. A new solenoid body service tag must be installed over the current solenoid body service tag on top of the transaxle case.

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Maintenance/Service and Repair.
2. Disconnect the mass air flow (MAF) sensor electrical connector and the wiring harness fastener from the air cleaner assembly.





3. Disconnect the brake booster vacuum hose from the air cleaner outlet pipe.





4. Disconnect the engine breather from the air cleaner assembly.





5. Remove the air cleaner assembly bracket bolt.





6. Loosen the air cleaner outlet pipe clamp at the throttle body and remove the air cleaner and air cleaner outlet pipe assembly.





7. Remove the transmission fluid drain plug and allow the transmission fluid to drain.





8. Install the transmission fluid drain plug.
^ Tighten to 9 Nm (80 inch lbs).





9. NOTE: The coolant hoses do not need to be removed from the engine.

Remove the coolant hoses from the transmission fluid filler tube and position aside.





10. NOTE: The coolant hoses have been removed for clarity.

Remove the transmission fluid level indicator.





11. NOTE: The coolant hoses have been removed for clarity.

Remove the nut, rotate the transmission fluid filler tube counterclockwise 90 degrees and remove the transmission fluid filler tube.





12. Loosen the transmission fluid cooler tube fitting from the thermal bypass valve.





13. Remove the transmission fluid cooler tube bolt and the transmission fluid cooler tube.





14. Inspect the transaxle case to make sure that the transmission fluid cooler tube seal and backing ring were removed with the transmission fluid cooler tube and are not stuck in the transaxle case. If the transmission fluid cooler tube seal or backing ring are stuck in the transaxle case, remove the seal and backing ring.





15. Disconnect the transaxle electrical connector.





16. Remove the 2 nuts, pull the transmission fluid cooler thermal bypass valve straight up and position it aside.





17. NOTE: Note the location of the of the stud bolts for assembly.

Remove the 14 bolts and the transaxle main control cover.





18. Disconnect the transmission range (TR) sensor electrical connector.
1 Slide the lock over.
2 Press the tab and disconnect the connector.





19. Disconnect the turbine shaft speed (TSS) and output shaft speed (OSS) sensor electrical connectors.





20. CAUTION: The solenoid body should be handled with care, damage to the solenoid body may occur.

NOTE: Note the location of the different length bolts for assembly.

Remove the 11 bolts and the solenoid body.





21. CAUTION: Do not handle the solenoid body in the leadframe area or by the screens of the solenoid body filter or damage to the solenoid body can occur.

CAUTION: Use care not to break the alignment tabs when installing the solenoid body filter. Damage to the transaxle will occur if the solenoid body is not correctly aligned.

Remove the solenoid body filter assembly by pulling it straight up from the alignment tabs. Discard the filter.





Installation

1. CAUTION: Do not handle the solenoid body in the leadframe area or by the screens of the solenoid body filter or damage to the solenoid body can occur.

CAUTION: Use care not to break the alignment tabs when installing the solenoid body filter. Damage to the transaxle will occur if the solenoid body is not correctly aligned.

CAUTION: Make sure that the filter passage areas are clean of foreign material before installing the filter. Damage to the transaxle will occur if the filter passages are not clean.

Install a new solenoid body filter assembly by pushing it straight down on to the alignment tabs.





2. CAUTION: Make sure not to pinch the TSS, OSS or TR sensor wiring harnesses when installing the solenoid body. Damage to the wiring harness will occur.

NOTE: Install the different length bolts in the locations noted during disassembly.

Install the solenoid body and the 11 bolts.
1 42 mm (1.65 inch) bolt
2 63 mm (2.48 inch) bolts
3 80 mm (3.14 inch) bolts
4 95 mm (3.74 inch) bolts





3. Tighten the solenoid body bolts in the sequence shown.
^ Tighten to 12 Nm (9 ft. lbs).





4. Route the OSS sensor wiring harness and connect the electrical connector.





5. Connect the TR sensor electrical connector.
1 Connect the electrical connector.
2 Slide the locking tab over.





6. Connect the TSS sensor electrical connector.





7. Inspect the transaxle main control cover seal for damage and install new if necessary.





8. CAUTION: Inspect the 20 pin solenoid body connector seal to make sure that the seals is on the inside of the main control cover. Transmission fluid leak will occur.

NOTE: Install the stud bolts in the locations noted during disassembly.

Install the transaxle main control cover and install the 14 bolts.
1 Bolt location
2 Studbolt location





9. Tighten the main control cover bolts in the sequence shown.
^ Tighten to 12 Nm (9 ft. lbs).





10. Wipe the surface of the existing solenoid body strategy tag on top of the transaxle case clean and install the new solenoid body strategy tag (supplied with the solenoid body service kit) over it.





11. Position the transmission fluid cooler thermal bypass valve and transmission fluid cooler tube assembly in place and install the 2 nuts.
^ Tighten to 11 Nm (8 ft. lbs).





12. Connect the transaxle electrical connector.





13. Inspect the transmission fluid cooler tube backing ring and seal for damage and install a new backing ring or seal if necessary. Lubricate the transmission fluid cooler tube seal with clean automatic transmission fluid and install the backing ring and seal on the transmission fluid cooler tube.








14. Position the transmission fluid cooler tube in place and install the bolt.
^ Tighten to 11 Nm (8 ft. lbs).





15. Tighten the transmission fluid cooler tube fitting.
^ Tighten to 25 Nm (18 ft. lbs).





16. Install the fluid filler tube and the nut.
^ Tighten to 11 Nm (8 ft. lbs).





17. Install the transmission fluid level indicator.





18. Route the coolant hoses in the transmission fluid filler tube.





19. Position the air cleaner assembly in place and install the bolt.
^ Tighten to 11 Nm (8 ft. lbs).





20. Tighten the air cleaner outlet pipe clamp at the throttle body.
^ Tighten to 5 Nm (44 inch lbs).





21. Connect the engine breather to the air cleaner assembly.





22. Connect the brake booster vacuum hose to the air cleaner assembly.





23. Connect the MAF sensor electrical connector and connect the electrical harness fastener.





24. Fill with clean automatic transmission fluid to the correct level.
25. Download a new solenoid body strategy to the PCM.
