   What causes transmissions to fail? It has been proven that heat is the #1 enemy of an automatic transmission. When the transmission fluid temperature exceeds 250 degrees, the abilty of the fluid to provide proper lubrication is greatly dimished. We recommen a transmission temp guage on all high performance and towing applications. We also recommend a quality auxillary transmission oil cooler. We can sell and install both of theese items for you. Just ask during your next visit or when making an appointment. The second most common cause of failure is overloading. Towing beyond the transmissions capacity, especially at high speeds and in hot weather. If you are towing a large boat or camper, is your vehicle rated for the weight of the trailer? Is your vehicle equiped with the proper towing package? Be safe, make sure you do not exceed the towing capacity of your vehicle, have an auxillary cooler installed and slow down with a trailer behind your vehicle.
