Automatic Transmission Rebuilders Association
ATRA is the only not-for-profit professional organization dedicated to the improvement and welfare of the automatic transmission repair industry for the benefit of the motoring public. Founded in 1954, it is the world's oldest and largest network of independently owned and operated transmission rebuilding firms.
ATRA serves as a non-profit association to provide the most current technical information to the automatic transmission industry, as well as providing consumers with automotive knowledge.
ATRA also administers a nationwide inter-shop warranty plan called the Golden Rule Warranty which ATRA members may offer the motoring public. In effect, ATRA members "guarantee" each other's work by agreeing to correct any defects in workmanship and materials done at another participating shop.
