Query: Great Auto Trans Cooler

This is an excellent automobile automatic transmission cooler for your car. It fits nicely on most cars right in front of the condenser and radiator. Just remember to put some insulating foam between this and the condenser. If this cooler touches the condenser it will transfer the heat to your conderser coils and reduce the efficiency of your A/C system dramatically. The only better cooler is an even bigger cooler.
