Transmission dipstick?

[RaptorTremor]

I'm at 24k miles on my truck and have been wanting to perform a transmission fluid check. I'm aware that basically all modern fords don't have a conventional trans dipstick now but they do have a small bolt in style dipstick like on 10r80s and 6r80s. I figure the 10r140 would be the same. I checked the owners manual first and found the page saying it's a sealed unit that doesn't have a dipstick. BS! I crawled under the truck to have a look, I found the fill bolt and what looks like a dipstick above the pan on the passenger side. I'm not sure if that's actually a dipstick so I haven't done anything so I can ask if anyone has tried it yet. Here is a picture of what I'm talking about

As soon as I take delivery of my 2021 F250 Tremor I will climb under truck and verify. This is a topic I have pondered thinking it crazy to design a "sealed unit" with no way to assess fluid level or coloration from operation.

Absolutely. I plan on changing the fluid close to 50k miles to be safe

Could the fill bolt be the “dipstick “, like on diffs?

That's what appears to be the case. I still would hope for some way to inspect the fluid condition and level while not changing it.

All new vehicles are sealed units which bothers me to.
Was always use to checking the fluid and dropping the pan every 50K and replacing filters.
Plus there might even be a magnet in the pan that will need cleaning.

Haven't even broke thousand miles yet but I will find the proper way to service these transmissions when the time comes.

May even crawl up under truck today and see what's up.

I found the manul on how to do the fluid change and filter. It looks way easier than other fords. There is a magnet in the pan but I don't think it comes out. I still want to wait and see about an aftermarket pan with a drain on it.

I'll be looking for aftermarket myself.
No drain plug sucks and tranny fluid taste

Can you post the fluid change procedure?

I emailed Mag-Hytec today, they responded within minutes. Here’s what the email said.

There's a drain plug:

"The Ford 10R80 has a fill plug and dipstick on the passenger side of the case like the 6R80 transmission. The dipstick has three different fill marks, A, B and C. These fill marks are model dependent and should be verified with factory information when the fluid level is checked (Figure 11)."

This company makes a pan and includes a better photo of the factory dipstick and access to the pan:

So climbed underneath truck and took couple of photos.
The TC is cut and dry and simple to get to, drain plug and fill plug.

Found a fill plug on driver's side of transmission.

The transmission pan has a tin shrouding that has to be removed before accessing the pan bolts.

 

[Marley]

Might be easier than first thought because those types of fill plugs are fill it til she runs out.

Yes that's the procedure

That's good news. My hopes would be that it is a replica of the OEM pan but with a drain plug and not plastic. Im not a fan of larger pans with more fluid.

Well they are known for making larger pans that hold more fluid, with cooling fins, with a magnetic drain plug, and with a built in dipstick.

 

[DesertMC]

Thanks guys for all the information. My truck is supposed to be built today, we will see. So I hope to take delivery by the end of the month. Then one thing I will do is crawl around under the truck to familiarize myself with the locations of these features.

Thanks again.

I hope it is larger with greater fluid capacity. That’s part of the problem with the OEM pan. Not enough fluid and it’s too hot. No place for heat to escape.
