Does anyone know what the correct trans fluid level is for the 2019 and newer trucks? I’ve seen the dipstick that has the “ A” and “B” readings but mine has numbers 1-6 starting at the bottom of and going up. Never seen any mention of this before.

Where is the level supposed to be at full operating temperature?

6-Speed or 10-Speed?

It’s a 10 speed. At full operating temperature it’s only about 1/2 inch from the bottom of the stick. I suspect it’s about a pint to 1/2 qt low.

ive seen the checking procedures that say to put it in the middle of the “ B” but this stick is probably “ revised”

Yes I’ve seen this before. But that picture has the A and B fluid levels.

mine has numbers 1-6

Slowcar281

Oh man I feel dumb. I just read the whole thing and it mentions numbers

looks like it’s exactly where it’s supposed to be. Thank you!!!

Yeah, it's supposed to be between 5 to 6, which seems lower than 'B' for my 2018. Wonder why. Anyway, was your fluid low??? I also noticed 2019s apparently don't have a freaking plug torqued to 50+ ft/lbs to cover the dip stick. Did yours? At any rate, I'm glad the proper way to check it is fully hot, although my truck has never seen more than 201F, but it's close enough to the minimum 205 (mine has maxtow/maxcooling). I plan to check mine one of these days, but have to see if I'll be able to do that while in my garage, especially with that tight-***** cover plug. Has anybody done this in their garage? Thx.

no mine wasn’t low. At 205 degrees it was at the top of the #5 which is good enough for me. And yes the 19mm plug was stupid tight when I initially took it loose. Needless to say I didn’t tighten it back up to 50 ft/lbs. but seriously watch out reaching for that plug with it so close to the catalytic converter. I wore gloves and still managed to burn my forearm. It is crazy hot

The transmissions are filled at the factory by a computer so it would be impossible to get it wrong.

I sure wish they filled the differentials correctly. I checked mine the day after I bought it, and couldn’t touch any oil with my finger. The spec is 2.75 qts for the rear and 1/4 inch below the fill hole. It took NINETEEN ounces of gear oil to get it to that level.

I opened the transfer case and couldn’t touch any oil there either, took SIXTEEN ounces of mercon LV to get it to where I could touch it with my finger.

seems kinda crazy but I remember my 2013 F-150 was the same way.

I talked to a guy who used to work for Ford and he said that’s it’s not uncommon for the rears to be underfilled because they are filled by weight, not volume.

anyone who hasn’t checked their diffs, I definitely would. I’d be willing to bet they are low
