What's the 2010 Toyota Corolla transmission fluid capacity?

The 2010 Toyota Corolla has a transmission fluid capacity of 6.9 quarts. You'll typically want to use only 4 quarts, though, if You're doing a simple "drain and fill" type operation, where You replace a little more than half of the current automatic transmission fluid. The reason You might consider doing this is because Toyota asserts that the ATF is a lifetime fluid, and doesn't typically need changing. But, if You do change it, You'll keep any suspended particles and other foreign detritus out of Your tranny. You can pick up Toyota's 00289-ATFWS Lexus & ATF WS World Standard fluid for $45 at Amazon, which gets You A4 pack of 1 quart bottles, which ought be what You need here if You're doing the drain and fill.
