YOUR TRANSMISSION FROM OVERHEATING AND IT WILL LIKELY OUTLAST THE REST
OF THE VEHICLE
According to The
Automatic Transmission Rebuilders Association (ATRA), an International
trade association for the professional automatic transmission
repair industry, approximately 90% of all automatic transmission
failures are due to fluid (ATF) breakdown caused by excessive
heat. As ATF heats up it becomes oxidized and loses its
ability to lubricate and cool the transmission. Poor
lubrication causes friction, which produces more heat.
For these reasons, it is highly recommended that you routinely check
your transmission fluid level and condition. Once a couple of
months is sufficient for most vehicles. But, for older
vehicles and vehicles with more than 150,000 miles, the fluid level and
condition should be checked monthly.
Spending 5 to 10 minutes once a month checking your vehicle's
transmission fluid level and condition could save you thousands of
dollars in repair bills.
it Hype or Real?
below provides a graphic illustration of just how devastating excessive
heat is to the life expectancy of an automatic transmission.
It's an eye opener for most vehicle owners!
rule of thumb is that for each 20 to 25 degree increase in temperature
above the normal transmission operating temperature the transmission's
life expectancy is cut in half. Keeping your transmission
cool is key to longevity.
