Yesterday mine passed state inspection and received an ATF machine flush and fill. It's been 50,000 miles on the previous fill.
Today, because the shops' machines tend to overfill transmissions, I pumped out 3 pints of ATF and added a bottle of Lubegard Red. The level is midway between the add and full marks now, in the middle of the crosshatching.
I've been driving the truck a bit, then siphoning out the power steering reservoir and topping it with Mercon V. The color is starting to become reddish now. Bought 4 more quarts of Mercon V from Walmart today to continue the process.
Now don't laugh too hard at me when you read this. Yesterday, when I started the truck the get the items in the first paragraph done, the engine revved to 3,000 rpm and stayed there. I couldn't see anything wrong under the hood. The revs didn't slow when the truck was put in gear, but the truck behaved as though the throttle had jammed. It was necessary to keep the brake pedal mashed as hard as possible. I nursed it to an auto shop around the corner, only to find the shop was closed. I walked to my neighbor's, called a tow truck, and got the truck to another shop.
Stupid me had pulled out the WeatherTech floor mat to clean and vacuum the interior, and I had put the mat over the accelerator pedal. The truck was fixed in seconds after the shop looked at it. The shop didn't even charge me for it, but I did have to pay the tow bill, of course. Now stop laughing. You jerks.
