gear oil temp on 2002 Isuzu Trooper

what is the recommended working temperature of the oil in the gear (auto transmission)? what is the minimum temp and the max temp?

The oil should be about the same temperature as your coolant, in fact it is cooled by the radiator itself. So, it needs to be about 160 for minimal functionality, after a warm up period of course and over 225 degrees, well that is getting close to the point where it may burn the fluid.
