AAMCO is a nationwide auto repair franchise with more than nine hundred locations. The Pearl River franchise is located just off of Route 304 on Washington Avenue. AAMCO has a reputation for being experts in transmission repair and replacement. However, it offers much more than transmission work. This shop offers complete car care, including drive train, suspension, heating and cooling work, oil changes, engine overhauls and performance enhancements. AAMCO also offers free checks for vehicles that have "check engine" lights on.
