Transmission Cooler and Guage

[hoytman62]

What is the best Transmission Cooler for my 2006 Jeep Wrangler X TJ? Where do I get the Temperature Gauge for it?

Hayden coolers are good and available at most auto parts stores. They'll have guages too.

A neat option is installing two temp sensors on the transmission, one on input and one on output. Then use a switch so the Guage can switch between sensors. You can then see how efficient your cooler is and watch for transmission issues.
