Long's Tru-Cool 40K GVWR Trans Cooler Install

I sent these pics to SleeperS10 already per his request, but I wanted to post them up here as well in case someone out there wants to know what a 40K GVWR cooler looks like installed in front of CW's radiator and condensor.
Some may question wether it's too big or that there's too much media in front of the fans to cool, but I can attest that in 110+ degree days in SoCal last summer, these fans kept my coolant temps UNDER 200 degrees, regardless of the condensor and huge cooler. Anyway, enjoy!

Re: Long's Tru-Cool 40K GVWR Trans Cooler Install

I didn't go as far as installing a trans temp gauge, but in those hot summer days in SoCal I removed the grille after a lenghty drive and the cooler was only luke warm

I have thought about it, but I will prob never do anything that would facilitate the need of a gauge. I heard lots of good things about them though, and the full size guys have had great results with high stall converters.

Re: Long's Tru-Cool 40K GVWR Trans Cooler Install

i guess my only concern with this is the required thermal bypass for areas that see below freezing...im assuming it operates like a thermostat somewhat and "opens" at a certain temp?

I can't remember if mine is 4739 or 47391....mine is the one without the thermal bypass and no, teperatures here are too temperate to worry about one.

Re: Long's Tru-Cool 40K GVWR Trans Cooler Install

I have also heard about those thermal bypass deals failing, more than I think is allowable. I don't have all the proof to back that up though.

Re: Long's Tru-Cool 40K GVWR Trans Cooler Install

I would like to order this tranny cooler but i will be driving my blazer all season long. What do you have to do different with the cold weather bypass?

Also, what fittings and lines did you guys end up using?

Did you use new line from the tranny use whats already there?

The Long's cooler I have has both inlet and outlet on the bottom of the cooler. I just ran the lines.

Re: Long's Tru-Cool 40K GVWR Trans Cooler Install

Has anyone install this in a daily driver who drives in the winter? I live in Iowa. I need to do something about my tranny being cooler then engine temp. I am getting a small leak at the top tranny line to the radiator. Wonder if having a brush guard hinders cooling?

Thanks,

i've driven mine in about 35 degree weather but not often. My trans ever hits 180, but you can cover the front so it heats up in winter. Its a great cooler.

Re: Long's Tru-Cool 40K GVWR Trans Cooler Install

I have the same cooler, when I talked to Chris at Circle D this is what he recommend. They also sell a part that will tee into the stock radiator to bring the temps up for winter drivers. My truck never sees cold weather anymore so I don't worry about it.
