Need HELP!!!!!! Trans Cooler?????
Hello everyone, I have a question I just installed a Tru Cool Cooler (V10) direct swap.. I was wondering if it was wise to hook up my old trans cooler in line with new.. Just wondering, has anyone done it before or have any idea it's possible... just trying to reuse and benefit from it...

I am not sure I would do 2 coolers in series. Could it have bad side effects by raising the resistance of the fluid path too much? Some have said it could. I would have and did dump the stock cooler and just went with the 6.0 since I want to do it only once and have it done right.
Hook it, I'll pull it.

Cost wise it is better to get the 6.0. Two Tru-cool coolers cost $300.

Surface area is one thing. My concern was that each cooler has some sort of resistance. 2 in series might be out of spec but if Brian said it was ok for his transmissions, I'll go along with it unless Mark K comes along with some test results he has gotten from his days with Ford.

I never ran two air to oil coolers in series. I would worry that the resistance would be too high, but I don't know that.
I don't understand how surface area would have any impact on this. We are talking resistance to oil flow, not air flow.
The 6.0L cooler uses 1/2" passages compared to 3/8" on the other coolers, so comparing sizes is like comparing apples and spare tires.

I may add that the extra U bends in the case of two coolers would impede with fluid flow. How much is it? I do not know.
