    Default Tru cool cooler cold weather bypass.

    Hey Guys,
    My 05 yukon xl has a 4L60E in it. I am looking at installing a tru cool 40k trans cooler because I do tow a heavy boat now and then and what the heck, why not? So, I was reading around the web and found that a lot of guys have had issues when installing the cold weather bypass that comes with the kit. They are saying that it causes a flow restriction and their trans is showing a hotter temp than it did before install. I also remember reading somewhere that my trans has a bypass that stops sending fluid out to the cooler in cold weather until it warms up. I have no idea if this is true. My question is, did anyone install the cold weather bypass and have an issue? not have an issue?. I am concerned that I install the cooler and next winter it is below zero and my trans never warms up. Suggestions? Ideas? thanks!
