Tranny Fluid Temp gauge

[RedEnvoyDenali]

I am planning on installing a tranny cooler in the very near future. I would really like to have an idea what temp the fluid is running at. However I don't want to put a gauge in the cab (no where it would go nicely). Is there any point in splicing one under the hood, into the tranny line from the cooler to the existing transmission lines? Would it give any kind of accurate reading about towing temps or running temps considering the time it would take to stop, lift the hood and read the gauge or would it always cool down to quickly to get a reading? So much information on this site it I am always.

You need to splice it into the line between the transmission and the first cooler. You want the temperature from the torque converter, where the heat occurs. You could hide it in the center console.

Thanks Double D that makes sense to get it in before the first (radiator) cooler. Hadn't thought about the center console since it has so much other junk in it. Do you think it will hold the temp for a couple of minuets after stopping?
