70k Mile Tranny Filter Replace

Just did a trans fluid exchange on my explorer. Dropped pan installed new filter, cleaned pan and magnet. Fill it up, removed cooler hose and back flushed the rad and auxiliary cooler with cooler flush. Put hose in a graduated container then started engine and used the trans pump to pump a quart out shut off engine add a quart and repeat until oil coming out is as clean as what is going in. It takes more oil to do it this way because converter has no drain plug but it is thorough. I added a Magnefine in line filter, it shifts nice.
