We build quite a few transmissions here but I never knew what we were missing! This hot flush machine for transmissions coolers is a game changer. Not only
Do we run this on all of our rebuilds before they go in but as a preventative maintenance if the fluid is dark. We have seen cooler flow gains anywhere from 1 gpm to 3.5gpm. If you are rebuilding your own transmission, had one rebuilt or are concerned with debris in the pan come see us!
