4-Speed Automatic Transmission

Transmission Fluid Temperature Sensor Inspection
Immerse transmission fluid temperature sensor (1) in water or oil. Check transmission fluid temperature sensor resistance between terminals of connector. Thus make sure its resistance decreases as temperature rises.
If sensor resistance is out of specification, replace solenoid wire harness (2).

Transmission fluid temperature sensor resistance
10 degrees C (50 degrees F): 6.445 k ohms
25 degrees C (77 degrees F): 3.5 k ohms
110 degrees C (230 degrees F): 0.247 k ohms
