Your vehicle's transmission system does a crucial job of controlling the transfer of power from the engine to the driveshaft. The power should be delivered to the wheels in a proper way to keep your car running optimally at the full range of speeds. Actually there's no system more complex than the transmission, and no other system gets more abuse over time due to a great amount of heat and friction generated by numerous moving parts.

    The system as critical as the transmission should never be neglected. The basic thing you can do to keep your car's transmission in top condition is to change the fluid at regular intervals recommended by the manufacturer or more often in case of frequent stop-and-go driving, towing, or hauling heavy loads. Failure to do so can cause transmission damage, as the fluid is crucial for proper lubrication, transmission cooling, and easy gear shifting.

    Transmission systems never go from great to bad immediately. Before giving you a big trouble, the transmission usually shows tell-tale signs that indicate a problem. If you've noticed a difference in the way your vehicle shifts, found leak spots on the driveway, or noticed that your vehicle suddenly loses power, rumbles, idles incorrectly, etc., it's time to take it to a mechanic. We provide quality replacement transmission parts and fluids that you and your mechanic will need for a repair or maintenance job. Automatic Transmission Governors, Modulators and other components are available here to restore a reliable level of transmission performance.
