Transmission cooler for drag racing

Last Saturday it was 95 and humid. the Last 3 rounds they damned near hot lapped us. I can cool my motor down, but after the final round I noticed the transmission (727) was 220-230 degrees.
I have the standard aluminum trans cooler in front of the radiator. Do any of you use one of the DeRale units or something similar and if so where do you have it mounted?
