How many quart of tansmision fluid does the TSX hold? I am thinking about doing a transmision fluid change.. Thanks in advance.

The manual transmission holds 2.1 quarts. Not sure about the automatic.

 

You'd need 3 quarts for the auto. Be sure to use Honda fluid.

 

If you want to do a full flush, you need to drain and refill multiple times, 3-4 iirc.

I bought the ATF-Z1 from my local Honda dealer for like $7/qt. I got 10 of them which should suffice for the 3 drain and refill requirements. If I think I need to do a 4th I can just start it up and drive to get the last two. Drain and then refill again and be all set.
