How else would you check trans temp if it is not showing on factory gauge? I know if i had a after market Edge with the screen i could see the actual temp.
I didn't know a factory tranny temp gauge existed, that's why I asked. The stock gauges are all but useless. They literally just float in the middle between hot and cold when they're at normal temps. If it exceeds a certain temp, it will peg and you get the warning lights. I know this is how the oil temp gauge works, so I would assume the transmission one would be the same. It's almost a joke. Maybe get an aftermarket tranny temp gauge? They're VERY easy to install. THe 5R110 is set right up for it.
