transmission flush
So lets hear it guys. Can a car with 99,000 miles have the transmission flushed? My boss bought a 1991 acura legend, and his mechanic will not flush the tranny because it has over 90k and they believe it will harm the seals. Anyone experience a problem after a flush?

My experience in this area is limited to GM cars but I haven't had any trouble. I never do the "Jiffy Lube" type flush however. My indy drops the pan, changes the filter then tops off the level. He then disconnects the line going to the tranny cooler and starts the engine. As the fluid is pumped through the torque converter and out the bleed he replaces it with fresh fluid until the exiting fluid runs clear. Shut it down, button it up and adjust the level until correct.
This would not harm the seals unless fresh fluid is bad for them.

Do your own flush and do it before you have problems. Learn to flush the coolant lines and passages in the radiator also. If you wait until you think you may have problems, like almost all people do, you blew it.

Fresh fluid will have MORE additives than the old fluid, therefore fresh fluid is better for the seals.
I know some people think that fresh fluid will ruin an old tranny; I disagree, fresh fluid will never hurt a tranny that is in good condition. If it fails after a fluid change, it would have failed w/o the fluid change. Its just convenient to blame the fluid when the real casue was the previous 90,000, ( or 120,000, or whatever) miles.
