Dealership service departments, national transmission repair companies such as AAMCO and local repair shops all offer transmission installation. If the transmission goes out, these companies generally offer repair services as well.
While mechanics at dealerships ostensibly have the best training with the parts, repair costs at a dealership are often significantly higher than at other repair shops. Shops that focus on transmission repair and installation, such as AAMCO, often offer similar levels of expertise to that of mechanics at a dealership but charge less to complete the work. According to the AAMCO website, the company offers a nationwide warranty on installation, rebuild and repair, offering customers the chance to return the car to another location if the transmission has problems during the warranty period.
When choosing a local transmission installation service, calling several to receive quotes helps to get the best deal. Reputable shops should be able to provide price quotes for transmission installation over the telephone without having to see the car. Also, third-party websites such as Yelp provide customer reviews that indicate the quality of service others have received from those companies. Perusing the positive and negative experiences that others have had with a garage helps the consumer choose the best mechanic.
