I put atf4 in and it calls for dexron vi. I believe the two quarts of atf4 I put in are gone. Can I add my dexron now?

Good morning.

The two quarts has mixed with the rest of the fluid.

I would drop the pan and change the filter and add the correct fluid to be sure you will not damage the clutches.
