Transmissions: To Flush or Not to Flush?

ANTIOCH – Much like a “quick stop” oil change, a transmission flush provides a fast and affordable means of maintaining a vital vehicle component. However, upon closer inspection, this convenient service may not be as good an idea as it appears.

The problem with a transmission flush is it only addresses the fluid itself, which means components like the filter and gasket are ignored. While the fluid gets changed, any debris buildup inside the transmission case gets left behind, most of which becomes trapped in the filter. Over time, if the filter becomes plugged up with debris, it can result in a worse issue with the transmission than existed previously.

For this reason, instead of having your transmission flushed, take your vehicle to an auto technician for regular transmission service—preferably every 30,000 miles. The technician will remove and replace the pan gasket, filter, and fluid, which will keep your transmission running cleanly and smoothly.
