ATF fluid change, the easy Korean way

[JD525IA]

good idea by uropal from South Korea, using a shampoo bottle pump for that

He measures exactly the volume pumped out and refills the same amount.
Of course, ATF filter is not changed then, but a good idea for a in-between-change.

I just rigged a glass chemistry vapor bottle with some rubber hose and attached my vacuum cleaner to it. The fluid was drawn out via vacuum and went into the bottle and not the vaccum because the tube attachment was about 1/2 inch below the opening of the bottle. I admit that I did warm it up before doing this so that it would flow faster.

Wouldn't it make sense to measure the volume after it cools and then put back in the same amount, at the same cool temperature? You could also get some idea of the change in volume in the fluid at the hi/low temperatures.

Does tranny fluid really change in volume at different temps?

Any hoo, the whole contraption looked like some college kids hooka or bong. Matter of fact, I've got an idea!

I'd pay to have seen that.
