I wound up flusing it. It shifts smoother now, pistons engauge and disengauge with out sticking or any more clunking. Should of did it a while ago. Must be an old wives tale. Clean is better than dirty in a pressure sensitive componunt with tiny orifaces in the valve body. I ruled out the theroy that a flushing dislodges particals because the actual flushing is less pressure than what is created in normal driving conditions. The old clutch material acting as a friction modifier makes a little sence, But the fact that oil breaks down and loses its lubricating properties is a fact. New oil will lubricate better than old oil. I personaly think people who flush a trans who are not careful and allow the pan to run dry whan the trans is pumping out the old flud and the front pump sucks up a nice air bubble frying the clutches. Thats probably the culpret. You get some just out of high school kid working at jiffy lube operating a machine between getting high on coffee breaks and he doesnt fill the pan fast enough and you burn out a clutch... that sounds more practical to me. If 1000 transmissions get flushed today and 1 breaks next week we hear about the one that broke, we dont hear abouty the 999 that run better. Then again who knows, my truck may be on the back of a flat bed by the end of the week and i will be eating my words...
