trans cooler (again!?)

I just installed my trans cooler about a week ago, and it seems to be working pretty well. Problem is, theres what Chiltons describes as a trans fluid "heat exchanger" inside the radiator. It looks like this is just a *very* small tube (1/16 of an inch maybe) that runs from the top of the radiator, just under the fill cap, coiling down to the bottom, then returning to the trans. I need to know if I should have put the trans cooler before or after this heat exchanger, or bypassed it completely, replacing it with the cooler.

Any help appreciated!

Thanks,
Chuck

Chuck, the best way to install your auxilary trans cooler is to go from the outlet pressure line from the trans, into the cooler in the radiator, then from the outlet of the radiator into the aux. cooler, then from the aux. cooler (obviously) back to the trans. The reason for this routing is because the fluid will be cooled better in the auxilary cooler than in the radiator cooler. So if it went to the aux. first, it would then be heated back up a bit when traveling through the radiator. If you hook it up the way I described above, the fluid will cool down a bit going through the radiator, then recieve aditional cooling in the aux. cooler. Hope this helps! good luck!
