You most likely do not have a external tranny unit. If you do, you could see it through the grill mounted in front of the radiator. I had to install a permacool tranny cooler on my truck with the addition of the stall and shift kit. If you are planning to tow alot, I would suggest getting one. I had someone put mine on, but the instructions will pretty much tell you what to do.
You could get the Denali/Escalade cluster for your tranny temp. gauge. The cluster comes with a tranny temp. gauge where the delete is on our trucks -plus you get a 120mph speedo. The cluster is a direct fit and just plugs in and you have your gauge plus better looking cluster. And you won't have to run wires or lines or tap into any lines. The only drawback to doing this is the odometer; the new one starts back at 0 miles so if you want your odometer to be accurate you will need to get someone qualified to set your mileage back or either put a sticker on the inside of your door telling the mileage before you switched the clusters. I can't wait until I get one of these clusters. I really need to keep an eye on my tranny temp, and I would like to see it everytime I drop the needle past 120.
