6. Install a Cooler Line Filter.20-Apr-2016
All automatic transmissions have some type of filter inside them. But these filters vary in effectiveness. Meanwhile, loose dirt and metal particles can quickly erode thrust washer and bushing surfaces, clog up passages, and reduce transmission life. One of the best ways to eliminate these contaminants is to add an in-line filter to the transmission cooler lines. These filters are inexpensive and highly effective in removing damaging particles from the transmission fluid.
