Trans oil
 

Is their any way to get all of the oil out of a 2004 Odyssey automatic transmission? Seems to me draining 4 quarts & refilling just mixes new oil with old.

Welcome in,most people change the fluid two times or more to get more of the old fluid out,or have the trans flushed .

Thanks for the answer bucwheat. I agree, you sure can get a lot of miles out of them.
