What is a Transmission Flush?

A transmission flush is a maintenance service that involves removing old transmission fluid and replacing it with new fluid. Unlike a simple fluid change, which only replaces a portion of the fluid, a flush ensures that all the old fluid is removed, along with any contaminants or debris that may have accumulated in the transmission system. This process helps maintain optimal performance, extends the life of your transmission, and prevents costly repairs down the road.
