I wouldn't want ATF on non-trans rubber seals, but it also has fine solvents and cleans hands great.

Rick Walker Carbs assembles their rebuilds with it and recommends the quart per 20 gal for old motorhomes and trucks.

ATF doesn't hurt seals, it's oil, very light weight oil. Has additional additives and cleaners but oil none the less.
