Installed drain plug and temperature sender in transmission pan

I reused the thin rubber gasket as it was in perfect shape. To make sure I added a line of RTV.

Here is a comparision of the drain plug and the transmission temp sender that I installed instead of the drain plug. I like to monitor the transmission temp in the pan.



The pan installed with the sleeve for the sending wire.



I routed the wire up and thru a hole next to the transmission and then up to the firewall and on to the gauge.
I was careful to avoid the exhaust or the turning driveshaft.

I installed the temperature gauge in a Carbon Fiber Pod on the left side of the dash along with a Vacuum Gauge.



I showed where to drill thru the firewall and the dash top on a pervious thread.

You can also install a temperature sending unit in a tee inserted in one of the lines that run to the cooler. The line running from the transmission to the cooler would show the highest temps, but it is up to you. You would want to establish a normal temp for either location and then you would know if it is running hot. Also be sure that the "Tee" does not obstruct the flow of fluid in the line. I did the pan because it is a real mess to drain the transmission without a drain plug to first drain most of the fluid. The only drawback it that some mechanic in the future may take the shortcut of not removing the pan when changing the fluid. That is really an oversight function that you need to address.
