AUTOMATIC TRANSAXLE (M13 ENGINE) 7B1-111
Transmission Fluid Temperature Sensor
Inspection
1) Disconnect negative cable at battery.
2) Lift up vehicle.
3) With engine is cool, remove drain plug and drain A/T fluid.
4) Install drain plug. (Refer to “Fluid Change” in this section.)

6) Remove oil strainer assembly.
7) Remove valve body assembly referring to “Unit Disassembly”
in this section.

CAUTION:
When pulling solenoid wire harness out of transaxle

ature sensor at narrow exit of case.
Careless sensor treatment might cause sensor malfunc-
tion.
