I have a 2011 Silverado 1500 5.3 and I am getting ready to install my tru cool. I live in Colorado where it does get cold, I got the thermal bypass but no one else is using them that I can see. Anyone have any experience using these on a newer model truck with the bypass in cold weather? I also got the install kit from Time2kill, but the only way to use the bypass is with rubber hose and I really didn’t want to do that either...any suggestions?

anyone have any slippage before trans comes up to temp?

thanks

 

The trucool bypass isn't really set to a good temp for our trucks. Just run your trans fluid thru the radiator like factory and you should be good to go as that will help bring the trans up to temp.

 

I’m here in Buffalo, NY and I just run through the radiator then to the cooler. No issues for several years now.

 

Sounds good, thanks for the advice

 

I have read the entire thread. One thing I did not see mentioned. Is there a process for bleeding the air from the system once cooler is installed? Or, is it just run it till warm. And, add to full again.

 

No need for anything special. Just start it up and top the fluid off.

 

Awesome, thanks. I've got all my parts and pieces together. At this point I'm just waiting for warm enough weather to throw it in.

 

I want to run an lines, but i have absolutely no clue were to connect the lines into my transmission (6L80) its a 2016 gmc sierra. Please help and how do i know which line goes were?

 

I’m about to install an external cooler on my 2013 Yukon it did not come with the auxiliary cooler only the radiator cooler. Should I completely bypass the radiator cooler and only run the new aftermarket cooler I live in South Texas currently the hottest transmission temp. I have seen his 220 in stop and go traffic.

 

You can and probably should bypass the radiator cooler. It will run cooler staying away from that. And, where you live that will never be an issue.
