Hi all newer owner if a 07 suburban ltz black on black. This week is the first Tim I've towed with it I think I have about 2 thousand pounds in a trailer and maybe 1 thousand in side with kids and dogs and stuff my question is how hot its it safe to run my Tran in got up to 234 on a pass and the light didn't come on and I just don't wanna run it to hot and also any tips on keeping it cool I've been using towing mode on any hilly surfaces I just don't wanna burn up the trans being stupid

even on the hottest days with me running around town with the truck constantly shifting I don't go past 200

Mine as well, it has never gone above 200 but definitely floats around the 195 mark in traffic during a hot day.

Dang, even lifted with 35's the highest I've ever seen mine is 181. Most days it stays at 150-160. That stock trans cooler must do better than I thought.

I have a 2012 5.3, 6 speed with factory cooler...while towing my 29 ft travel trailer, the hottest I saw was 215°...I since added a Derale inline cooler and haven't seen above 175° while towing! Only cost me $75 and I found a discount coupon for Etrailer.com on a google search...worth a shot!

get the tru cool max from oregon performance transmission. their best price is from the website itself. also a guy on ls1truck has brackets for the nbs and may have them for the nnbs for a seriously easy installation (mainly the fittings and such to make it a very easy process to connect to the existing trans lines)
if you have a factor trans cooler, it makes it a LOT easier to do.

mainly just has good pictures of where/how to mount the cooler. not so much the lines. but we just cut the existing hard lines and slipped the rubber lines over and used double clamps to make sure it holds nice and tight. if you have a hard line flaring tool, that would be ideal to insure a leak-less install

best price was amazon, i just bought one last week. (Came from OPT)
so no leaks from just sliding the rubber hose over the oem line?

ah your previous link wasn't working. nice.
and nope, no leaks. i used two hose clamps per hose and it was pretty snug when i put it on there. we checked it after a month and it was dry as can be.
