The "vroom vroom" comes from the engine, but a car or truck goes nowhere without a functioning transmission.
Whether you shift the gears yourself or a vacuum does the work for you in an automatic, the transmission is a critical part of the car.

Ashland Automotive owner Zach Edwards joins us for another edition of The Squeaky Wheel. We talk tranny issues and take listener calls and emails about these and other car troubles.
