STANDARD VALUE SPECIFICATION

Fluid temperature °C (°F)	Resistance kΩ
10 (50)	Approx. 6.62
25 (77)	Approx. 3.51
80 (176)	Approx. 0.55
110 (230)	Approx. 0.25

CAUTION: The transmission fluid temperature sensor cannot be removed or replaced as a single unit. When the transmission fluid temperature sensor needs to be replaced, replace the valve body assembly.

When the resistance of the transmission fluid temperature sensor is outside the standard value, replace the valve body assembly and the harness.
