I don't want this thread hijacked but . . .
I was always taught the 'drop pan' method was the best way to change the fluid. Theory: You'll only change ~1/3 quantity so the new fluid mixes with the old fluids and tones down the aggressive detergents in the new fluid. Using all new fluid in a hi-miler slushbox will eventually clean out all the embedded clutch pack fiber that is aiding the soft kit seal off internal leaks and skew port timing. Gradually, the shifts will soften, reverse engagement slows, and then shifts hang.
Hey, one guy swore by reusing the old fluid after filtering it through a pair of his wife's old pantyhose. (OK, OK, OK, enough of the jestings. . .)
But hey, I'm an old school mech and been told theories do change over time.
To repair a vehicle by replacing a component is an accomplishment,
to repair that vehicle by rebuilding that component is a passion.
