Transmission Oil Temperature Gauge

p4 dm 03.03.004

The transmission oil temperature gauge, (see Fig. ) measures the transmission lubricant operating temperature. Temperatures vary by application, but the transmission fluid temperature gauge reading should not exceed 250°F (121°C).

  1. Engine Oil Temperature

  2. Turbo Boost Pressure

  3. Transmission Oil Temperature

Notice: A sudden increase in transmission fluid temperature that is not caused by a load increase may indicate mechanical failure. Bring the vehicle to a safe stop and investigate the cause to prevent further damage. Do not operate the vehicle until the cause has been determined and corrected.

Under heavy loads, such as when climbing steep grades, temperatures that exceed the normal oil temperature range for a short period are not unusual. If the temperature returns to normal when the load decreases, there is no problem.
