Abstract:
A method of removing contaminants from a transmission cooler comprising the steps of:providing a transmission cooler having transmission fluid therein;coupling a first hose to said transmission cooler at a first point;coupling a second hose to said transmission cooler at a second point;providing a plurality of electrically operated valves between said first hose and said second hose;providing a pump for circulating said transmission fluid through said first hose, said second hose, and said transmission cooler;providing a filter exterior of said transmission cooler and between said first point and said second point for collecting contaminants from said transmission fluid;providing an electrically controlled source of compressed air;recirculating said transmission fluid through said first hose, said second hose, and said transmission cooler;heating said transmission fluid;injecting bursts of compressed air from said electrically controlled source into said transmission fluid at predetermined intervals as said transmission fluid recirculates through said first hose, said second hose, and said transmission cooler;checking said filter to determine the level of said contaminants present;determining whether said filter should be cleaned;cleaning said filter if needed, such that once said filter is cleaned the flow direction of said transmission fluid through said first hose, said second hose, and said transmission cooler is reversed.
