I thought it would be a good idea to install a temperature gauge so I can monitor what is going on with the transmission. I bought an Autometer gauge for around $38.
You will also have to drill out the oil pan and weld in a fitting. Here you can see the steel fitting that is welded to the pan. Then the brass fittings from the temperature sensor screw into the pan. Pick your location wisely since clearance is tight. The spot I chose is next to the dipstick tube.
You will need to do some wiring. 1 wire runs from the sensor to the gauge. The rest of wires can be tapped into circuits found under the dash.
