Then I switched to this engine
oil cooler:
this is the same type used in NASCAR,in fact I bought it used from a NASCAR team.... Almost identical to your average transmission
oil cooler... It worked better than the two above, but still not good enough for my application, it was just too small in size.....
Then I saw this one:

It's off a 2010 Ford F-150 Super Crew truck,it's the trans.
oil cooler,it was free, so I tried it and guess what,it works... It is exactly twice the size in square inches as the NASCAR cooler and has the same size inlet/outlet and almost identical size "plates".....
with this cooler I now have a 20 to 25 degree difference in oil temp, which I needed as I have run oil temps of 250 to 270 degrees with the other coolers. Now my oil temp stays in the 210 to 225 range!!!!!!
With this cooler I have about 8 psi less oil pressure across the rpm range than without any cooler.....
here is a pic of the two coolers side by side for size comparison....
