[QUOTE="Richard L, post: 771691, member: 52972"] The flush has always worked for me. I like flushes because they replace about 98% of the old fluid, while dropping the pan only changes about 50-60% of the old fluid at the most. Modern transmissions do not have drain plugs on the torque converter and that holds about half the fluid and dropping the pan does not get the fluid out of the torque converter. Some will argue that the filter is not being changed when you flush. U don't feel that is a real issue since the transmission filter is not designed to trap and hold cntaminates like an engine oil filters. The transmission filter is realy only a screen to prevent larger chunks debris from cirulated back throught the transmission. Once the engine is shut off, the pump suction stops and the particles stopped by the filter drop to the bottom of the pan where a magnet holds the metalic particles. If you have your fluid flushed every 25K-30K miles your filter should last a good 100K miles and you would only have to change it every 3-4 flushes and you will only have to drop the pan when the filter needed changing. ...Rich [/QUOTE]
