Watched videos and everything is going great but found this in the transmission pan. Want to confirm what it is and where it goes. Don't have much knowledge on transmissions.

 

Toss it, it's a plug that drops out when they put the dipstick in at the factory. Not needed anymore.

 

^^ Bingo, found the same thing in my parents 1996 Mercury Mountaineer's 4R70W when I did their ATF in 2010..... they got their money's worth out of that mercon.

 

Curious as to how much transmission fluid you put in after everything was buttoned up. My '17 just turned 80K and I'm thinking about changing mine.

 

Glad I saw this lol I plan on doing my transmission this spring and good to know if i find that its normal

 

Found something similar in my 72 F-100 many years ago. Over 100k and evidently the first fluid change.

 

My '17 came with a drain plug in the pan (factory). I changed fluid and filter at 60k. It took just a bit over 7 quarts. I drove the truck a bit and then (twice) did a drain and refill. It took 7 quarts each of those times.

I also bought a reusable LubeLocker gasket, only to find that the factory gasket was reusable. I could have saved those $$s.

 

Good to know, thank you. Unfortunately I don't have a drain plug in mine so it's going to be extra messy. My plan is to replace the OEM pan with one that has a drain plug. Also, all the videos I've watched about this fluid change, the filter just drops out with the pan when the pan is removed. Did you experience this and did the new filter stay in when you installed it?

 

The Dorman pan has a drain plug on it and its pretty economical.

I have one on my 6R140 on my 2019. Has held up ok, I am getting a little rust on the surface and the dorman drain plug rusted on me. Granted my truck is my daily, plow truck and I work for a Salt distributor so mine gets more corrosive exposure than most. I replaced the drain plug with a stainless steel one with a magnet on it when I last did my ATF in the fall. If you get one I would recommend a coat or two of paint just as insurance.

My filter didn't fall out, you do want to make sure the seal comes out of the hole the filter mounts in.

 

Thanks for the tip Rufus. I was thinking since I'm going to replace the pan on my 6R100 with one that has a drain plug, can I just drill a hole in the OEM pan to drain the fluid? Where would be a safe place to do that on the pan? Assuming the lowest point I can see being very careful and very slow.

 

When I swapped mine out, I took out all the bolts and left the front two to let the pain splash down into the 15 quart catch pan I have had forever. Then I just zipped the last two bolts off and carefully lowered the pan with ATF in it. Didn't make too much of a mess. A broken down cardboard box helps as a backup catch all.

 

6R100 filter falls out and takes a little skill to get it back while lining up the pan at the same time, it doesn't stay in by itself. The 6R140 filter is fastened in place and doesn't drop. My pan has a drain plug from the factory, got lucky I guess..

 

Yes, the filter does just drop out. As Morehouse said, it can be a bit of a PITA to get it to stay up in place.

 

I drilled mine to avoid the mess. It's a 6R140 but the principal is the same. Here's a thread with pictures and suggestions to keep it less messy. https://www.ford-trucks.com/forums/1...ssion-pan.html
