I assume it's an LS1 & auto.

Have you asked Warwick? He will know exactly what you require to keep your auto cool. I know the stock factory coolers are not good enough for club day track work, just something a little bit better than that I expect. Tony Stark had his LS1 auto Harrison at Cobra Nationals last year. Warwick will know what was required to stop the auto overheating.
