Fluid is under constant high temperature and extreme hydraulic pressure.
The internal friction can create heat in excess of 175 degrees Fahrenheit, which is the usual temperature range at which most fluids are designed to operate. As a rule of thumb, every 20-degree increase in operating temperature above 175 degrees Fahrenheit cuts the life of the fluid in half. Replacement in accordance with vehicle manufacturer recommendations allow new fluid to continue to clean, cool, and lubricate internal parts, extending the life of the internal parts. Filter replacement is included with our service to insure that new fluid is not quickly contaminated with foreign particles, providing filtered lubricant for internal parts at all times. Clean transmission pan and mounting surface.
