Transmission Flush Service

How a transmission flush works?  A transmission flush procedure is generally performed using equipment that runs off the transmission pump.  The machine is connected to the transmission cooler lines, and while the old fluid is pumped out, the new fluid is delivered at the same quantity and time.  The cooling lines, cooler, converter and other parts are all thoroughly cleaned.

One of the benefits of this procedure is that all of the transmission fluid is removed and replaced.  This is different from a fluid change in which only some of the fluid is replaced.  A simple fluid change cannot remove all of the built up deposits that accumulate over time as is done during a flush.  Also, some of the fluid is usually still in the torque converter potentially contaminating the new fluid that is put in.
