Trans Temp Gauge install Q's

[Dave06xlt]

I'm looking to install a tranny temp gauge in my 06 XLT, V6 and am looking for some advise on Brand gauge and placement (in-line at Trans, in-line at Cooler, using pressure port if available). I'm looking for the least invasive process possible.

Thanks for any advise, especially if you've already installed one please let me know who well your install seems to be working for you.

Thanks!
Dave
