Thanks for the lanolin link.
Ordered some, received it, refined my method and got better results. I glopped the lanolin into a funnel, put the funnel over a jar, put the jar on a block of wood in a pan of boiling water. Once all the lanolin ran into the jar, I put a bottle in the boiling water, poured the lanonlin into the bottle using the funnel, then took the bottle out of the water and poured the ATF in and shook the bottle. Keeping the jar and the bottle warm allowed the lanolin and ATF to mix; from there, adding the relatively cool moneral spirits simply diluted the mixture.
Wasn't perfect - the cool neck of the bottle solidified some of the lanolin while shaking. Need to stir next time, I guess.
