I am looking into getting a tranny cooler. And heard mixed reports on the size to get. I 1st heard that u should not get a supersized tranny cooler, but rather get a tranny cooler that is closest to the weight of the vehicle. Yet others say that interms of cooling there is really no sense of overkill.

Now I have done enough research that shows that tranny fluid need to be between a certain operating range to function correctly. But I can't figure out if a HUGE tranny cooler will bring the fluid below it operating temp.

Now to throw alittle twis into this equasion. I will be purchaing a B&M trannycooler. The B&M has bypass valves installed in the cooler that prevents cold tranny fluid from passing through the cooler. When fluid gets to operating temp the fluid thins out and becomes thin enough to pass through the bypass valve and through the cooler.

So tell me what u guys think.

I have a Hayden tranny cooler. But in general its a good thing to get. Don't get too big cause it takes longer to heat up, thereby shifts are not as smooth till you warm it up. I'm not too sure about a tranny bypass. I think its bullshit if you ask me.

 

I got a Hayden

Hayden & B&M make good TCoolers. I believe I have the Smallest One they make.

 

I got a Hayden too

Description:

B&M's SuperCooler low pressure drop coolers reduce the risk of lube system failure. A controlled amount of ATF is allowed to bypass the stacked plate core, passing through a self-regulating orifice which monitors resistance to flow. Controlled by viscosity, the thicker ATF is returned directly to lube through two open bypass openings in the stacked plate core. As operating temperatures increase, more of the ATF flow is directed through the core. Resulting in a highly efficient cooling technology that combines improved protection against lube system failure with the required levels of optimal heat transfer.





Hope this explins much.

In your region I would not be worried about going too big. A 24k unit would be fine which is what I had installed in my '01 CL-S.

If I were in the northern parts of the county I might be more concerned about going too big and the effect during the winter. But in FL you should be more concerned abot having enough capacity. Anything from a 18k to 26k unit would be adequate.

 

Cool .

Now how do u feel about the cooled fluid that gets returned back to the tranny? Do u think that it could have dropped down in temp so much that it is out of its operating temp range?

It doesn't cool it down to the point to where it would not be within operating limits. I suspect that it would drop to about the 180 range from about 210 - 220. Remember, trand fluid starts deteriorating and damage starts when the fluid exceeds 240 F.

The trans can function normal at 160 F.

 

SWEEEEEEEEET .

I'll be placign my order for a Super Cooler Tonight.


TNX!!!!!!!
