Tips Overview

Automatic transmission fluids must perform many demanding functions. These include helping transfer power from the engine to the transmission via way of the torque converter, a hydraulic fluid for the control system inside the transmission, a heat transfer medium to help maintain proper transmission temperature, a lubricant and an energy transfer medium for bands and clutches.

Quick Tip

Transmission fluid should be changed while doing the 15,000 mile inspection and changed again each 15,000 miles, or about every year, for long life.

Because of these demands we recommend fluid changes no less than every 15,000 miles. Transmissions withstand the torture of summer's heat and winter's slip-and-sliding.

Not too many years ago, there were only two types of automatic transmission fluids used: Type "A" was used in General Motors vehicles and Type "F" in Ford. Today, the specifications change from year to year and by manufacturer. Consult your owner's manual or a shop manual if in doubt.
