Re: Trans Temp sender location
I'm not too familiar with scan gauge products but if you want to add a trans temp sensor only you can do so for a LOT less cash. There are aftermarket gauge pods you can get for $15, $10 for wiring, $15 for sensor and about an hour to drop the pan and install the sensor (shops will charge a moderate fee for drilling the pan and installing the sensor).
The best place is to put it low in the pan where it will be full of fluid at all times. Putting the sensor in/around a trans cooler line isn't as accurate and the pan will be much warmer then any of the lines to the cooler.
Some trucks did come with trans sensors, mostly diesel or V10 trucks only. As electronics are better implemented to all vehicles some are equipped with trans temp sensors.
