GMT 800 Towing Package?

[Rocket Man]

Thank you for the first hand knowledge you said it drops it 20 degrees that is a big improvement over stock.Thats what i wanted was someone that had it done already with a trans temp guage.Its interesting that yours doesn't get over 180 if what he said is correct about the valve not opening till 180 slightly and fully open at 200-it must open before that or right at that maybe he is off a little.If it didnt open till 180 you wouldnt even be using a cooler then if it were shut tight.

Yep and the advertising I've seen says it's fully open at 180.

Couple of more points I just wanted to add (as someone who bought my GMT800 - 04 Suburban 1500 - specifically to tow a small trailer):

1. As others have said, the 1500 'Burb/Tahoe and non-Denali Yukon did not come from the factory with a transmission temp gauge. I'm ASSUMING that the rare 06 LTZ version (that had the 6.0 V8) did come with one, since the Denali, Escalade, and 2500 models - all with 6.0 or 8.1 V8s - came with the trans temp gauge. As I understand it, the trans temp gauge is linked to whatever engine the vehicle came with: 4.8 or 5.3, no trans temp gauge, 6.0 or up (this includes all Escalades, Denalis and all 2500 vehicles) had the temp gauge.

The good news is that the sensor is already there so if you just add an instrument cluster with the gauge, it will work. My instrument cluster went out last year and I had it rebuilt by the folks at Circuit Board Medics with all new stepper motors and green LEDs, and for an extra $100 they added a trans temp gauge (far left in this picture.)

2. I believe the tow package also included the 145a alternator. I would definitely recommend upgrading the alternator if you haven't already. It's an easy job and well worth the extra power. I'm running two batteries and powering a refrigerator in my truck so I need all the power I can get!

Got a pic of the fridge and location of it? What size inverter are you using? I've been thinking about doing that in my work van.

Yeah my cooler keeps my trans running pretty cool. I rarely see temps above about 150 or 160 u less I'm down off the mountain in the summer and its in the triple digits. Which happened yesterday. Lol. But the mi ute I got up higher in elevation and the outside temps dropped like 20 degrees in a few thousand feet, it cooled right back down.

Fridge is a chest type and sits on the floor. 12v, no inverter needed.
