Default Is there a way to cool trans fluid with engine off?

Sometimes in hot laps I need to cool trans faster. Is there something I could use to cool it in the lanes with the engine off?
I have a small cooler with a fan on it, but it don't cut it sometimes.
I have EWP and can cool the coolant in seconds.

Many run a small pump off of the oil pan circulating a fan/cooler combonation. I used an adjustable relay with a temp sensor in the oil pan. I also run it off a hotwire so it runs until the trans is down to the preset temp in between rounds.

What kind of pump do I look for? I can use the cooler I have with the fan and get the pan tapped if I had a pump.

I use the smallest of the three in this link, I think it was around $250 delivered with the extra fittings.
Weldon makes a really good pump but it costs a lot more. I used the hayden thermostatic relay, its adjustable down to 90* and has a bypass so you can run it nonstop if you like.
