One thing Jeep missed out on the JK was a transmission temperature gauge. With all the talk of JK transmissions getting hot, especially on the Unlimited, I was interested to see what my tranny temp was.
So, I installed a B&M Transmission Temp Gauge. Installation was straight forward. I mounted the gauge on my Daystar upper dash panel rather drilling holes in my dash. I mounted the sensor in the return cooler as recommended by B&M. I mounted towards the front as this was the easiest place to cut the line and work on it. I connected the back light up to the dash dimmer circuit.
The gauge is a B&M 80212, which comes everything you need, gauge, pod, temp sensor, etc.
Of course as soon as I finished it started raining, sun disappeared and temps dropped by 20°F, but it still gave me a good indication of tranny temps. On the highway with the tranny locked up I never broke about 140°F, in stop and go driving it got to about 160°F. Nothing that looked bad at all, although I was more concerned about off-road temps and for those times the tranny works harder.
At least I will now know the transmission temp and be able to see when it starts getting hot.
