ANTIOCH – Host, Sarah Rutan: A transmission flush is a popular service, but according to some automotive professionals, it may not be such a good idea. Today we’re in Antioch with Diamond Certified Expert Contributor Chester Kniss of Delta Transmission to learn more.

Diamond Certified Expert Contributor, Chester Kniss: A common question we get asked about is doing transmission flushes. I don’t recommend a flush because when you do a flush, you’re actually just exchanging the transmission fluid out. You’re not changing the filter and the gasket. And the problem you run into is, on a high-mileage vehicle, they get debris stuck inside the case, and if you put the  fluid back into it, it cleans the fluid out, it traps the debris, puts it up into the filter, and, in turn, this plugs the filter up, and causes more issues than you started with, with the transmission. We recommend doing a service to the vehicle. We remove and replace the pan gasket, and the filter, and the fluids every 30,000 miles, to avoid that occurrence.
