How much oil?

[CTScott]

If you just drain it via the drain plug you will only get less than 2 of the 6 quarts out. If you also drain the tranny cooler portion of the radiator (by removing the hose clamps and pulling the rubber hoses off the metal nipples of the radiator) you will get another 1/2 to 3/4 of a quart.

Unless you pull the valve body and torque converter you are only doing about a 50% change with the amsoil.

From the spec document on the U340E transaxle:

Fluid Capacity Liters (US qts, Imp.qts) 6.4 (6.78, 5.63) (including differential)

BTW, I also plan on changing the Transmission filter.

The reason why I asking is because I have a 1997 Toyota RAV4, 5 speed. I installed an oil cooler and it works for both, the axle and the gear box.

Which means the transmission and the axle work independent from each other? Am I correct? Which Amsoil oil does the axle uses?

The Yaris automatic is a transaxle, which means it's an all in one unit. I am not sure on the amsoil AT Fluid. Toyota only recommends genuine Toyota ATF WS.
