- Vehicle ON, observe the scan tool Transmission Fluid Temperature and the ECT temperature parameter after a 9 hour cold soak. The readings should be between -50 to 149°C (-58°F to 300°F) and vary less than 15°C (27°F) at -40°C to -20°C (-40°F to -4°F) or less than 10°C (18°F) greater than -20°C (-40°F) from ambient temperature after an 9.5 hour cold soak. The transmission fluid temperature parameter should rise steadily then stabilize when the vehicle is driven for greater than 300 s.
- If greater than the specified range, or stuck at a fixed temperature
Refer to Circuit/System Testing.
- If within the specified range
Test for a transmission overheat condition. Refer to Transmission Overheats (5ET50) .
- Go to next step: If no automatic transmission overheating condition exists
- If greater than the specified range, or stuck at a fixed temperature
- Refer to Circuit System Testing.
