Abstract
The sensitivity of a rotary seal ring to transmission manufacturing operations and assembly techniques can effect the overall quality of an automatic transmission. In addition to those characteristics that make a seal functional in an automatic transmission there are other characteristics that facilitate the ease and simplicity of assembly in commercial manufacture. A combination of material properties, design, and manufacturing techniques combine to make thermoset polyimide seal rings an attractive alternative to other materials now in use.
