Time to Change Trans Fluid???
My recently purchased 2001 F150 supercab turned 100,000 miles yesterday. I bought the truck with 93,000 miles. I immediately changed the oil the day after I bought it just so I could be sure that it was clean. I'm thinking I should go ahead and change the tranny fluid being that I just hit 100,000. What type of fluid is recommended? How much? Any tips?

The 4R70w (trans code door sticker of U) is Mercon V

From 94 to 97 ford just used mercon in everything. 98+ 4R70Ws came stock with and are recommended to have Mercon V. At that time ford revised the 4R70w fluid requirements of older 4R70ws to use Mercon V. There is a friction modifier in Mercon V that Mercon does not have that the 4R70w likes.
Use Mercon V for the 4R70w.

Just finished changing my fluid. It went exceptionally well! All I did was follow the instructions on this website https://www.f150online.com/forums/li...ission_oil.htm
