Hi, when I worked at a GM dealership 20 years ago, every new truck that arrived off the truck required a quart of transmission fluid, every one. We in the Parts Department just called it "the usual". Having noticed some posts here, has anyone noticed this with Ford too? Is there a "usual" amount low in the 10 speeds as well? Saving a quart on each truck adds up very quickly when you make 100,000 trucks! Going to check mine this weekend as someone posted, it has to warm a minute to go in reverse when its cold. Mine shifts fine after a minute or two, no issues otherwise. Thanks

Yes ive heard many many 10 speed guys saying they are a quart low from the factory. I have yet to check mine.

Mine has the same hesitation as you describe.

That's good to know. It's not a big deal to me, an "old timey man" (Cheech and Chong) who likes to let the engine warm up a bit before driving, but if tranny low I need to remedy it! If you get to it before me let me know please.

Just read this same thing while researching aluminum transmission pans for 10R80 = was on a Mustang forum, which also shares the 10R80 -- trying to find links now....

There is no dipstick on these anymore. You have to check/add underneath the truck.

So I've read. "Ford's better idea", as they called it back in my day. Oh well, I am stubborn and will play their game, not my first rodeo.

At least with the ZF 8 speeds, you check the level at between 85F and 120F. Too cold and you can overfill and too hot it could be under filled. Sounds wacky, but supposedly temperature effects volume of ATF enough to be an issue. Had a Mercedes NAG1 in a Dodge Magnum that also had no dipstick. Anyway, I changed my Ram's fluid at 100,000 miles and did it at 100F.
