When the old fluid gets burnt and worn out, the transmission experiences excessive internal wear, this causes the unit to heat up, heat causes the glue on the clutches to become brittle and to crystallize. When new fluid is introduced into the unit, the high detergent aspect of the new fluid scrubs the old glue away from the back of the clutches rendering the transmission useless.

Also, the gritty debris in the trans fluid adds friction that is much needed with the extremely worn clutch packs from neglect and abuse. When you "flush" the old gritty metal filled fluid and replace it with slippery and heavily detergent laden ATF, you actually greatly increase the amount the transmission will slip, and eventually the transmission will fail.

I will surrender the fact that I may have used "PH" improperly in my above statement, I was merely trying to figure out a way to describe replacing a fluid that had burnt out the adatives with new ATF that has new detremental and harsh detergents.

Maybe you shouldn't pull advice out of your ass While the way I tried to explain it may have failed, don't ever come in here trying to "Flex your wings" on a subject you have no inkling of knowledge about. Sorry Mr. Biology, just flexing MY wings.
