AU TOM AT IC T R A N SMI S SION S An automatic transmission uses electronically or hydraulically controlled friction clutches to select gears. Although easier to operate, automatic transmissions sometimes require more maintenance. They also typically require an automatic transmission fluid. P R E MIUM AU TOM AT IC T R A N S MI S S ION F LUID S (AT F S) A R E DE S IGNE D TO: • Prevent metal‑to‑metal contact and wear • Promote efficiency in vane pumps, planetary gear sets and bushings • Maximize fuel economy • Allow low temperature operation • Control oxidation to guard against oil thickening • Provide correct frictional properties for shifting clutches • Be compatible with seals • Protect against thermal degradation. DI AGNO SING AU TOM AT IC T R A N SMI S SION PROBL E M S Using a TO‑4 fluid in an automatic transmission can result in: • Harsh shifts • Poor low temperature performance • Mediocre transmission response • Sludge and deposit formation • Copper and bronze corrosion Using a tractor fluid in an automatic transmission can cause: • Burnt shifting clutches • Elongated shifts • Inadequate holding capabilities • Sludge and deposit formation. An automatic transmission operating with an improper fluid will increase the likelihood of shortened component life, unscheduled downtime and elevated maintenance costs. Fluid choices for automatic transmissions should take into account severity of service, ambient and operating temperatures, which will influence viscosity grade selection, and any OEM‑required approvals.
