| − | The key to longevity in any automatic transmission is to keep the fluid cool; therefore installing an external bypass cooler is recommended. The factory transmission coolers are an integral part of the radiator and will only cool the fluid in accordance with the engine temperature. Transmission fluid life decreases as temperatures rise above 160º F. An external transmission cooler will help to prevent ATF breakdown and torque converter "ballooning" or expansion which will cause (catastrophic) pump bushing failure. Use the largest external cooler that will fit and not block radiator airflow. | + | The key to longevity in any automatic transmission is to keep the fluid cool; therefore installing an external bypass cooler is recommended.

It's just as important to let the transmission warm up before it takes abuse as it is to keep it from overheating. And, if you don't have an external cooler you'll have a great idea of when to take it easy on the trans. |
