Google says it holds 11.2qts, and you said "I installed it the next morning drained the remainder of tranny fluid from the pan drain hole and saw no metal shavings. Filled the 5 quarts back up and gave it a go."
Something doesn't sound right with the numbers adding up to 11qts. Maybe I'm misreading what you're saying?
Nope you are correct, it does hold 11 quarts, however only 5- 5.5 of it is recoverable from the drain plug. To get the full 11 out you have to drop the pan, which I'm not equiped to do.
