What started out just looking to add a trans temp gauge has drifted into looking at different programmers. I wasn't too knowledgable on them and was wondering if anyone here is running one and what are your thoughts?
I have an '99 Expedition but figured I would get more responses here

 

I have one in my 2000 Expedition and love it. that is how I started too, wanting to monitor trans temps. now I recommend to everyone who asks about programmers for these trucks. Nothing but good to say about it, just search some of my posts...
