Thread: Percentages question

Hi all. Im trying to figure out a few different percentages but math is not my strong point. I need to know how much of each fluid is being drained when I drain my transmission.

The transmission holds 7.6 quarts total

There is 4.6 quarts of amsoil fluid 60%
There is 3.0 quarts of type F fluid 40%

When you drain the fluid, only 3.0 quarts of the total 7.6 come out. If there is 60% amsoil and 40% type F fluid in the transmission, how may quarts and how much percent of each fluid is draining in the that 3 quarts?

THANKS

To be exactly consistent, there would be 7.6 x 60% = 4.56 quarts of amsoil fluid and 7.6 x 40% = 3.04 quarts of type F fluid. Close enough.

It sounds like the 3.0 quarts you drain and the 4.6 quarts left in the transmission are both 60% amsoil fluid and 40% type F fluid.

So the 3.0 quarts you drain is 3.0 x 60% = 1.8 quarts amsoil fluid and 3.0 x 40% = 1.2 quarts type F fluid.

I was thinking the same thing but it doesnt seem like it could be as easy as 60/40 of each fluid draining when there is 60/40 of each fluid in the transmission already. I really dont know though.

If this is true then is it safe to say that no matter what the ratio of fluid is in the transmission, it will always be the same ratio draining?

I'm not really an expert on transmissions. I would think the fluids would mix well, so that whatever drains out is the same mixture as what's left inside.

well there both synthetic fluids made by amsoil.

one is amsoil synthetic automatic transmission fluid
second is amsoil synthetic super shift automatic transmission fluid (type F)

back on topic lol

So is it safe to say that no matter what the ratio of the 2 fluids are in the transmission at any given time, you can drain any amount of fluid you want (1 quart or 5 quarts) and the same ratio will be draining that's already in the transmission? (assuming each fluid has mixed thoroughly and not separated)

Yes, that's correct. (But again, I'm not an expert on transmissions and transmission fluids.)
