The complexity of today’s automatic transmissions can baffle even seasoned technicians. Modern transmissions feature more gears, clutch packs and narrow oil passageways that require a steady supply of high-quality fluid. Without it, performance suffers and failure can ensue, leading to thousands of dollars in repairs.
To make matters worse, towing and hauling capacities continue to increase despite transmissions often using less fluid than their predecessors. Maximizing transmission performance and longevity requires using premium synthetic fluids.
“The fluid doesn’t just lubricate, it acts as a hydraulic fluid to enable shifting,” said Matt Erickson, AMSOIL Product Manager, Passenger Car. “Fluids that oxidize can result in damaging sludge that clogs fluid passages and results in poor performance. Transmission fluid is also exposed to high levels of shearing as it is forced between gear teeth. This can quickly break down an inferior fluid, causing viscosity loss and reduced wear protection.”
