Default Re: "S" Series automatic transaxle fluid/filter change

I've heard that, i can see how it can help and how also it would be worthless. i think it depends on the design of the valve body. i can't hurt anything that wasn't already in trouble.

let me also add the Wolfman's post. before changing the fluid. take a white paper towel. wipe a sample of ATF from the dipstick on the paper towel. if it is red, you are good. if it is a light dark red, its iffy. dark red, brown, or black - DO NOT CHANGE THE FLUID. if you see any grainy materal - DO NOT CHANGE THE FLUID. discolored fluid and grainly partiticiles are signs that the friction materal in the clutch packs have broken down, and friction materal is now curculating in the fuild. now the fiuld is acting as the friction materal in the clutch packs. at this point changing the fluid will result in the loss of that friction materal and result in slipping. also the materal from the clutch pack can dirty up the valve body causing sticking valves(which i have done : ). in short, if the fluid is in bad condicton, do not change the fluid, and a trans rebuild will be needed in time. follow the manufactior's service interval.
