AUTOMATIC TRANSAXLE (M13 ENGINE MODEL) 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.)

case, take care not to damage transmission fluid temper-
ature sensor at narrow exit of case.
Careless sensor treatment might cause sensor malfunc-
tion.
8) Remove solenoid wire harness (1).
9) Warm up transmission fluid temperature sensor (2). Check
resistance between terminals of valve body harness connec-
tor (1). Thus make sure its resistance decrease as its tem-
perature increase.
