I live in kansas and temps in the winter can get cold, I will drive the truck when it's under 30 degrees for sure. Should I get a 40k tru cool with the bypass or just stick with one that does not have the bypass? I will eventually have a cam, higher stall, headers ect...... Is a 40k cooler over doing it?
Edit: 04 RCSB
nope, the rad. cooler will also serve as a warmer in the winter. You should be fine. no bypass needed IMO.
Where in kansas are you?

When it gets to -10 you can always just put a cover over it.
So a 40k without bypass won't be too big/cool and I should be good with that one? Will the tru cool mount in front of the radiator on an 04?
Anymore thoughts? :)
Plenty of room to mount in front of the radiator.Quote:

Oh Nice....thanks for the pic :beerchug:
Anymore thoughts on one with bypass or not? Anyone live in below 30 degree weather without a bypass equiped cooler?
I think youll be fine. Just keep it running through your radiator too. If your truck is set up like that.
I will check to see if it is set up like that. Thanks fellow Kansian :)Quote:

I have a Tru Cool 28,000 GVW trans cooler with out bypass.Quote:

My temps says lower than what I would like. Rarely getting up to 180 o. In winter I cover the cooler with aluminum foil and cardboard and the temp gets up to about 130 o. This is driving around town. I have it hooked up to the engine radiator like you are supposed to.
Hope this helps.
Your in North Dakota....we are in kansas. We may not have the problem of temps like you had.
I'm wondering if just going with the bypass wouldn't be the safer route. It's only like $30 difference. Just trying to learn the pros and cons of it I guess. Never dealt with tranny coolers before so thanks for all the input guys.
So the final questions is....do I need a 40k or just go with a smaller one like a 28k? :)
Bigger is better but I just have a 30k with a 10 inch fan mounted to it. That would be plenty. I got a deeper derale pan with the cooling fins and I dont hardly use my fan anymore.Quote:

Below is part of the ad about the cooler.Quote:

As operating temperatures increase, the ATF becomes hotter and thinner. It's directed through the core where it is cooled.
Tru-Cool's highly efficient cooling technology combines improved protection against lube system failure with optimal heat transfer. "
That is built in the cooler. Tryed to find a pic. on the web to show you.
Tru Cool allso has an external bypass --one that looks like a " H " you plumb in the lines going to-from the cooler.
Hope this helps
I found the box--took a pic--of the internal bypass.http://www.ls1truck.com/upload/files/182/IMG_2808.JPG
