The best spot by far is right over the air dam, in front of the condensor. It can sit on that lip on the radiator/condensor shelf.

I put mine in front of the radiator more to the pass side. I have no A/C so the condenser isn't a prob. It should go before the radiator though.

i welded 2 pieces of angle steel to the top and bottom radiator supports and bolted the cooler to it.

When plumbing the cooler, use the tranny cooler in conjunction with the stock radiator converter.

Make sure that the finned cooler is downstream from the factory radiator cooler. I never remember which line is supply and return, so I undo one, start the car real quick and see which one leaked fluid.

The aftermarket cooler should be installed in the fluid path before the factory cooler, not after it.

Nope...everyone recommends putting the auxiliary cooler in the RETURN line after the factory cooler. In the summertime, the radiator tends to heat your tranny fluid even more, so you want some way to scrub out that extra heat (my theory). My tranny people actually refused to plumb a good cooler before the radiator because the "temperature drop to the fluid would be too much", whatever they meant by that.

Desert86Roc has got it right - tranny fluid into the radiator (usually knocks some temperatue down in the tranny fluid) then into the finned exchanger.

Look at the heat transfer medium. Air temperature is WAY cooler than warmed up engine coolent.
