Installing a Transmission Temperature Gauge in your Jeep

Personally, I enjoy my automatic transmission - It's nice around town, and is great for offroading, allowing me to focus on my lines, and where I'm going, instead of worrying about my clutch burning out, or engine stalling. While autos aren't for everyone, they definitely have their fans (me among them).

One of the biggest problems with an automatic in a Jeep is that the low speeds you see in rock crawling cause less airflow, making the transmission heat up quickly. Heat is the main reason that transmissions die, and once you cook your transmission your looking at some costly repairs. The sad part is that this is a pretty easily avoidable situation - if you simply knew when your transmission was overheating, you could let your Jeep cool down. That's where the transmission temp gauge comes in.

After some research, I decided to pickup a digital temp gauge, along with a sender (the sender gets mounted in the transmission pan). I picked the Cyberdyne Blue Ice Digital Gauge (part number A221E351Y) from Jegs. At around $80 it wasn't the cheapest, but it looked nice so I went with it.
