What I am thinking of doing is putting two sensors in and wiring them up to a switch right next to the gauge. one for Tranny, the other for transfercase.. or possibly the cold and hot. Just a simple pushbutton non-momentary switch.
One thing I am not too clear on is do the Transmission and transfer case swap fluid. if not is there ever any problems with the transfer case overheating? I have seen a gauge that has both transfercase and tranny temp gauges on it but its kinda hokey looking and figured this way would be a little easier to read.
