7.4 quarts is right on for bottom pan removal, shop manual says 4T65-E holds 13.4 quarts dry, so 7.4/13.4=55% change not the 40% alluded to in earlier posts. Last pan drop and filter change I also installed the 2 larger donut shaped magnets mentioned in a TSB along with using GM Dex VI since about 2008. Between doing the pan and filter change at about every 30k, I'll change out about 6 qts. thru the dipstick tube with a hand pump. I've heard to many horror stories about flushes besides GM specifically doesn't recommend them unless the trans cooler in the radiator needs flushed. 132k on what is known as a problamatic transmission and I hope to get to the 175k what is generally considered the maximum life before rebuild with maintanence.
