Control Module: Service and Repair
Control Valve With TCM and A/T Fluid Temperature Sensor 2
COMPONENTS
CONTROL VALVE WITH TCM REMOVAL AND INSTALLATION
Removal
1. Disconnect battery negative cable from battery negative terminal.
2. Drain ATF through drain plug.
3. Disconnect A/T assembly harness connector.
4. Remove snap ring from A/T assembly harness connector.
5. Push A/T assembly harness connector.
CAUTION: Be careful not to damage connector.
6. Remove oil pan and oil pan gasket.
7. Check foreign materials in oil pan to help determine causes of malfunction. If the A/T fluid is very dark, smells burned, or contains foreign particles, frictional material (clutches, band) may need replacement. A tacky film that will not wipe clean indicates varnish build up. Varnish can cause valves, servo, and clutches to stick and can inhibit pump pressure.
^ If frictional material is detected, perform A/T fluid cooler cleaning. Refer to A/T Fluid Cooler Cleaning.
8. Remove magnets from oil pan.
9. Disconnect A/T fluid temperature sensor 2 connector.
CAUTION: Be careful not to damage connector.
10. Straighten terminal clips to free terminal cord assembly and A/T fluid temperature sensor 2 harness.
11. Disconnect revolution sensor connector.
CAUTION: Be careful not to damage connector.
12. Straighten terminal clips to free revolution sensor harness.
13. Remove bolts A, B and C from control valve with TCM
14. Remove control valve with TCM from transmission case.
CAUTION: When removing, be careful with the manual valve notch and manual plate height. Remove it vertically.
15. Remove A/T fluid temperature sensor 2 with bracket from control valve with TCM.
16. Remove bracket from A/T fluid temperature sensor 2.
17. Remove O-ring from A/T assembly harness connector.
18. Disconnect TCM connectors.
CAUTION: Be careful not to damage connectors.
19. Remove A/T assembly harness connector from control valve with TCM using a flat-bladed screwdriver.
20. Disconnect TCM connector and park/neutral position switch connector.
CAUTION: Be careful not to damage connector.
Installation
CAUTION: After completing installation, check A/T fluid leakage and fluid level. Refer to Changing A/T Fluid and Checking A/T Fluid.
1. Connect TCM connector and park/neutral position switch connector.
2. Install A/T assembly harness connector to control valve with TCM.
3. Connect TCM connectors.
4. Install new O-ring in A/T assembly harness connector.
CAUTION:
^ Do not reuse O-ring.
^ Apply ATF to O-ring.
5. Install A/T fluid temperature sensor 2 to bracket.
6. Install A/T fluid temperature sensor 2 (with bracket) in control valve with TCM.
CAUTION: Adjust bolt hole of bracket to bolt hole of control valve with TCM.
7. Install control valve with TCM in transmission case.
CAUTION:
^ Make sure that turbine revolution sensor securely installs turbine revolution sensor hole.
^ Hang down terminal cord assembly and revolution sensor harness toward outside so as not to disturb installation of control valve with TCM.
^ Adjust A/T assembly harness connector of control valve with TCM to terminal hole of transmission case.
^ Assemble it so that manual valve cutout is engaged with manual plate projection.
8. Install bolts A, B and C in control valve with TCM.
9. Tighten bolt 1, 2 and 3 temporarily to prevent dislocation. After that tighten them in order (1 -> 2 -> 3), and then tighten other bolts.
10. Connect A/T fluid temperature sensor 2 connector.
11. Securely fasten terminal cord assembly and A/T fluid temperature sensor 2 harness with terminal clips.
12. Connect revolution sensor connector.
13. Securely fasten revolution sensor harness with terminal clips.
14. Install magnets in oil pan.
15. Install oil pan in transmission case.
a. Install new oil pan gasket in oil pan.
CAUTION:
^ Do not reuse oil pan gasket.
^ Install it in the direction to align hole positions.
^ Complete remove all moisture, oil and old gasket, etc. from oil pan gasket mounting surfaces.
b. Install oil pan (with new oil pan gasket) in transmission case.
CAUTION:
^ Install it so that drain plug comes to the position as shown.
^ Be careful not to pinch harnesses.
^ Complete remove all moisture, oil and old gasket, etc. from oil pan mounting surfaces.
c. Tighten oil pan bolts to the specified torque in numerical order as shown after temporarily tightening them. Refer to Components.
CAUTION: Do not reuse oil pan bolts.
16. Tighten drain plug to the specified torque. Refer to Components.
CAUTION: Do not reuse drain plug gasket.
17. Pull up A/T assembly harness connector.
CAUTION: Be careful not to damage connector.
18. Install snap ring in A/T assembly harness connector.
19. Connect A/T assembly harness connector.
20. Pour ATF into transmission assembly. Refer to Changing A/T Fluid.
21. Connect the negative battery terminal
