Default Trans coolers...

I need to get a better one in there....and I'm thinking of going with a dual circut model with a cooling fan in it...I wanna knock the temps down both in the engine and the trans....So I was thinking, get the dual circut and run my oil AND trans fluid in the same cooler, and keep temps down in both spots, so having 2 major heat fluids in the engine getting good cooling.....The cooling fan on the cooler too should help IMMENSELY with high ambient temps and traffic jam/track situations.

This is the unit I was thinking of going with:

http://www.jegs.com/webapp/wcs/store...tegoryId=10631

The 1250 CFM fan model.

Any thoughts, comments or concerns?

I might be missing if it has a thermostatically controlled setup for the trans fluid. You want to make sure that by installing this you aren't causing the trans to not reach operating temps.

Oil is great and can be cooled all day with beneficial gains. The trans does need to reach operating temp though. You might want to talk to Morty, he was looking at something similar for a trans setup that had a fan and didn't mention being thermostatic regulation for the trans fluid.

Ahh... good.

In that case, it looks good and should be large enough for your application.

That looks like a great transcooler and also it will benefit you, You can run a switch so that you can just activate the fan on very hot days. You can also benefit in running synthetic transmission fluid such as Redline or Royal Purple. Most temps are about the same as the engine so in both running at 200-210 would be about adequate.

Nate, I bought the larger of the two listed here. Just haven't installed it yet.

http://www.jegs.com/webapp/wcs/store...tegoryId=21061

Boost raised a good point with me and I haven't installed yet since I haven't been able to answer it:

Since you're bypassing the preheater element of the radiator and this cooler is significantly larger than your original, is it going to be able to get up to operating temp?

I guess we're both facing the question, regardless of which brand we go with. What are your thoughts?

Morty.. Nate'* cooler is thermostatically controlled and should restrict flow until 160 degrees.

So is the one I bought. It'* controlled at 175 degrees. The fan doesn't kick on until that point.

It doesn't answer the question though, as you pointed out to me in PMS.. will the fluid be able to reach operating temperature at all because of the size of the new cooler?

Uhm, Bill...Morty'* is thermostatically controlled too:

They include a thermal switch to activate the fan when the fluid temperature reaches 175F.

175* would be an ideal temperture rating.....Even a lil cooler would help, the cooler you get, the more miles you can save.....If I remember right, 15* can make the difference of 500-1000 miles of the life of the trans, or something like that, and also depending on how high the temps are to begin with. I have a table laying around somewhere, I'll have to see if I can find it or get another one.

During the winter months, I think having the fan switched would be a better idea, because it'll prolly never get hot enough. I'ld like to stay at about 160*, maybe a few more. Also that all depends on driving habits, area, and climate.

A trans will heat up to temps either way no matter what, but if it'* getting over cooled, the fan option being thermostatically controlled may be an issue, unless you can either adjust the point that it engages the fan, or put a switch on it and watch the temp from a scan tool/temp gauge.

I plan on installing a 3 wide line of Autometer gauges here in the next few weeks (You guys are gonna **** when you see that install ). Before I even install the cooler. Just so I can get a good baseline of before and after the install.....That way I can post the results of the particular model I intend on using for your guy'* benefit.

Also now that I think about it, if you're looking into a dual circuit cooler like mine, and you're trans runs too cool, you can flush it out, and set the trans on the 2 pass circuit and the engine oil on the 4 pass circuit. That way there'll be less of a cooling effect going to the trans.
