OIL PRESSURE SWITCH REMOVAL/INSTALLATION [GW6A-EL, GW6AX-EL]

id0517i2112600

Warning

•  A hot transaxle and ATF can cause severe burns. Turn off the engine and wait until they are cool.

•  Always wear protective eye wear when using the air compressor. If the air compressor is used, any particles of dirt or soiling could spatter and get into the eyes.

Caution

•  If the oil pressure switch has been replaced, perform initial learning. (See INITIAL LEARNING [GW6A-EL, GW6AX-EL].)

Oil Pressure Switch A

1.  Select the selector lever to P position.

2.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

3.  Remove the front under cover No.2. (See FRONT UNDER COVER No.2 REMOVAL/INSTALLATION.)

4.  Clean the transaxle exterior throughout with a steam cleaner or cleaning solvents.

5.  Drain the ATF. (See AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT [GW6A-EL, GW6AX-EL].)

6.  Remove the oil pan.

7.  Insert a precision flathead screwdriver and move it in the direction of the arrow to disconnect the oil pressure switch A connector as shown in the figure.

Caution

•  Do not scratch the oil pressure switch A and oil pressure switch connector A with the precision flathead screwdriver.

•  When disconnecting connectors, grasp the connectors, not the wiring harnesses. Otherwise, the wiring harnesses may be pulled out of the connector causing poor contact.

8.  Remove the oil pressure switch A fitting bolts.

Caution

•  Clean any remaining silicone sealant on the contact surface of the transaxle case and oil pan, and degrease the sealant area. Otherwise, oil could leak.

14.  Install the oil pan with new bolts before the applied sealant starts to harden.

15.  Add the ATF. (See AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT [GW6A-EL, GW6AX-EL].)

16.  Install the front under cover No.2. (See FRONT UNDER COVER No.2 REMOVAL/INSTALLATION.)

17.  Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

18.  Perform the “Initial Learning” (oil pressure switch A replacement). (See INITIAL LEARNING [GW6A-EL, GW6AX-EL].)

19.  Perform the “Mechanical System Test”. (See MECHANICAL SYSTEM TEST [GW6A-EL, GW6AX-EL].)

Oil Pressure Switch B

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Remove the front under cover No.2. (See FRONT UNDER COVER No.2 REMOVAL/INSTALLATION.)

3.  Clean the transaxle exterior throughout with a steam cleaner or cleaning solvents.

4.  Drain the ATF. (See AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT [GW6A-EL, GW6AX-EL].)

5.  Remove the oil pan.

6.  Remove the oil strainer. (See CONTROL VALVE BODY REMOVAL/INSTALLATION [GW6A-EL, GW6AX-EL].)

7.  Remove the oil strainer O-ring. (See CONTROL VALVE BODY REMOVAL/INSTALLATION [GW6A-EL, GW6AX-EL].)

8.  Insert a precision flathead screwdriver and move it in the direction of the arrow to disconnect the oil pressure switch B connector as shown in the figure.
