I recently put a tranny temp gauge in my ’91 4.0 auto with factory 2 row radiator and internal tranny cooler. I put the sensor in the “in” line for the tranny cooler (top hole on cooler, hi pressure side from tranny) so I can see how hot the fluid is coming out of my tranny. My gauge reads from 100* to 250* with 180* being in the middle. In 2 wheel hi running around town my tranny stays right around 180*. When I put it in 4 hi and start playing in the snow it will quickly jump up to 220*. This kind of alarmed me since the gauge only goes to 250* and I would assume that is the max temperature. Does anyone know what the “normal” operating temperature is for an AW4?
