A/T Fluid Temperature Sensor 2 Removal and Installation

A/T FLUID TEMPERATURE SENSOR 2 REMOVAL AND INSTALLATION





Removal
1. Disconnect the battery cable from the negative terminal.
2. Disconnect heated oxygen sensor 2 harness connector.
3. Drain ATF through drain hole.





4. Remove oil pan and oil pan gasket.





5. Check foreign materials in oil pan to help determine causes of malfunction. If the ATF is very dark, smells burned, or contains foreign particles, the 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 AT-14, A/T Fluid Cooler Cleaning. A/T Fluid Cooler Cleaning





6. Disconnect A/T fluid temperature sensor 2 connector.

CAUTION: Be careful not to damage connector.





7. Straighten terminal clip to free A/T fluid temperature sensor 2 harness.





8. Remove A/T fluid temperature sensor 2 with bracket from control valve with TCM.





9. Remove bracket from A/T fluid temperature sensor 2.

Installation

CAUTION: After completing installation, check A/T fluid leakage and A/T fluid level.





1. Install A/T fluid temperature sensor 2 to bracket.





2. Install A/T fluid temperature sensor 2 (with bracket) in control valve with TCM, and then tighten A/T fluid temperature sensor 2 mounting bolts to the specified torque. Refer to AT-231, COMPONENTS.





3. Connect A/T fluid temperature sensor 2 connector.





4. Securely fasten A/T fluid temperature sensor 2 harness with terminal clip.
5. Install oil pan to transmission case.
a. Install oil pan gasket to oil pan.

CAUTION:
^ Do not reuse oil pan gasket.
^ Install it in the direction to align hole positions.
^ Completely remove all moisture, oil and old gasket, etc. from oil pan gasket mounting surface.





b. Install oil pan (with oil pan gasket) to transmission case.

CAUTION:
^ Install it so that drain plug comes to the position as shown in the figure.
^ Be careful not to pinch harnesses.
^ Completely remove all moisture, oil and old gasket, etc. from oil pan mounting surface.





c. Tighten oil pan mounting bolts to the specified torque in numerical order shown in the figure after temporarily tightening them. Refer to AT-231, COMPONENTS.

CAUTION: Do not reuse oil pan mounting bolts.

6. Install drain plug to oil pan, and then tighten drain plug to the specified torque. Refer to AT-231, COMPONENTS.

CAUTION: Do not reuse drain plug gasket.

7. Connect heated oxygen sensor 2 harness connector.
8. Pour ATF into A/T assembly.
9. Connect the battery cable to the negative terminal.
