- rises less than 3 degrees Celsius,
or
- rises more than 10 degrees Celsius.

Diagnostic conditions:
- No electric fault for ATF temperature sensor detected
- ATF level OK
- Cold starting
- Test drive (with transmission output speed > 800 rpm)

- ATF level too low
- ATF cooling faulty
- ATF temperature sensor faulty
