Hi everyone, I've looked in the Isuzu trooper manual for how to check the oil level on the 3.2 petrol auto transmission box and it all looks straight forward apart from its very fussy temperature range that the gearbox oil has to be between.

My question is how do you know what temperature the oil is at? I was thinking of measuring it with a thermocouple, but that's no use if the auto box/ECU measures the temp in a different place to myself measuring it as it comes out of say the fill port. Does anyone know of a cheap Diagnostic tool that has a data list function to see the auto box temp? The method for checking according to the Isuzu manual is listed below:-

2. Check fluid level with engine running at idle.
NOTE: Be sure that transmission fluid temperature is
below 30
C (86
F).
3. Move the selector lever through all gear ranges.
4. Move the selector lever to “Park”.
5. Let engine idle for 3 minutes and open the overfill
screw (1).
6. Add released transmission fluid until it flows out over
the overfill screw opening.
7. Let engine idle until a fluid temperature between 32
C
(90
F) and 57
C (135
F) is reached, then close the
overfill screw (1)

Many thanks regards David
