Hey folks!
Just did a quick drain and fill on the 4.6. Bought 12 quarts since I read 2 flushes takes 6 quarts each times 2.
Well, just did the drain and when I went to fill it up, only 2.5 quarts was taken. HUH???? Procedure:
1: Loosen the fill plug. check
2: Open the drain plug and let it flow out. check
3: Plug the drain. check
4: Open the fill and started to pump trans fluid in. check
5: Fill started to pour out and plugged it right away. check
6: Started the X and ran though the gears... twice. check
7: Open the fill and added some more until it poured out. check
2.5 quarts total (probably a little less since I was still pumping a bit while it was pouring out.
So what am I missing? Thought each drain and fill in this procedure calls for 6 quarts.
Took it for a spin and she shifts a hell of a lot smoother but I still hear the BOV sound during each upshift albeit not as predominate (much more quiet).

What did I do wrong?
Thanks!!
