Theory of Operation
The Transmission Temperature Sensor is used to sense when the transmissiontemperatureistoohotortoocoldto
operate overdrive and/or the torque convertor clutch. When the transmission sensor detects a temperature below 0°
C (32° F), overdrive and the torque convertor clutch are disabled. When thedetected temperature is above 127° C
(260° F), overdrive is disabled and 3rd gear with TCC is engaged, this strategy is used to increase transmission
fluid flow to help cool the transmission.
When Monitored:
Continuously with the ignition on and the engine running.
Set Condition:
This DTC will set if the (T54) Transmission Temperature Sensor Signal circuit voltage exceeds 3.76 volts for
the period of 2.2 seconds.

Theory of Operation
The Output Shaft speed and other inputs are used to determine the current governor pressure. This directly effects
which gear the vehicle is in.
When Monitored:
Continuously with the ignition on, engine running, and gear selector NOT in park or neutral.
Set Condition:
This DTC will set if the vehicle speed (reported from the CAB module) is above 24 Kmh (15 mph), and the
monitored Output Shaft Speed is below 60 RPM for 2.6 seconds.

different than the expected voltage. Note: To clear this DTC, it is necessary to drive the vehicle at a sustained
speed which would allow the TCC and/or Overdrive Clutch to operate.
