I would add about 1/2 quart, then start checking it.

Thank you very much, for the feedback and being a customer!
Thank you sir. You did all the hard work of measuring , forming, and building this wonderful device. The only hard part I had was getting the cap off of the old dipstick.

I don't recall... Here is what I would do. Have a quart or 2 of fluid on hand.
I suspect you won't add a full quart.
  1. Check your fluid level cold. The process is outlined here. Keep the truck off as much as possible, Only run it to check the level, then immediately turn it off. The fluid heats up faster than you think.
  2. Fill it cold. add a little at a time - 3-5 oz or so. Use Mike's funnel.
    (You can pour more if you have a pump to pull fluid out via the dipstick tube.)
  3. Let the fluid settle down the dipstick for a minute or two. You need a nice accurate reading.
  4. Check it. It should be between the tip of the dipstick and 1/8 - 1/4" up. NO MORE
  5. If it is not, repeat steps 2-4 until it is.
Be Patient. It won't take too long to get it right. If you doing this relatively fast you may not need to run through the gears each time.

If you overfill you're going to have the opposite problem... and it won't show up until the transmission gets hot enough to push to 200F-215F, depending on how much over you are. Then you going to have a balky transmission with all the bad behavior you've seen reported on this forum.... then it vomits!

Looking forward to that update post! A little catch up here......I dont post much, just a Sleazy watcher LoL. I also just installed my MBS dipstick on my 2020 Lariat with 43k. (bought used 2 years ago with 40k ) Love My Ranger!

First....totally second all props to mike and his amazing dipstick kit! From fit and finish to price you cant do better! if any part of the install was tough it was from fords end.

Second my transmission has been amazing and yes it doesnt get used hard at all. But im in the minority that likes this tranny as mine is acting for now just as it should. I did add the FP tune and I feel the tune and Tranny relearn made it even better!

Now after a few checks I too am sitting right at the 6 plus line. about the 150 to 160 degree area. I am not sure exactly what to do. Ive read before other being right there and maybe this is a full boat at full operating temp and adding anything would be a mistake.

Everthing shifts so good I dont want to mess with it but I feel Like adding a half quart might be good.

Let us know what happens.

I know what you mean about purchasing dipstick 2 years ago. I, too, purchased mine about 2 ago, new from Mike, for my 2020 xlt. Got a new pan also, w/ drain plug. Going to install it all this next week. Have several appts coming up in Atl @ Emory. 250 miles one way. Wanna get her all squared away before all that Atl. City driving. I'm glad you all have shown us how to get the fill right. ✌

I appreciate that TJC but I was using the temp thing to show where I am on the stick. I'm not sure what the trans temp is. The trucks up to operating temp so I would think I'm low. Maybe not though.
