I like the tranny cooler in front of the a/c condensor on the driver side. This gets the coolest
air to the cooler and makes the air hotter on the side of the radiator that the thermostat is located on. Should open the thermostat a little sooner.
I left the stock radiator in series. On real hot days, 90 deg F and higher I found I needed that heat sink of the fluid.
There is a about a 100 deg F rise across the condensor and radiator on a hot 90 deg F day. I haven't checked the rise across the condensor yet.
