that;s easy
first ID what trans is there, of many. , seen on WIKI.
FWD or AWD ? not told
it is inside the box. and if you learned what transmission it is there.
GEN6-1/2 203 face lift. but
3.5 EcoBoost V6
2.0L EcoBoost Inline 4

the trans matches engine max torque output. so learn that then tell what is under the hood (and box and fwd/AWD)
why try to fix car, and not know what is under the hood
I can't guess what you own lacking VIN
even the dealer demands a VIN, for good reasons. PARTS
best guess me at ford.com is this 6speed box post 2012
so google parts for this and learn. easy. once learn what it is.......
6F55
your are asking how to build or repair a valve body?
seems no parts for the VB are sold..

they sells this and a zip kit

https://www.transmissionpartsdistributors.com/6f50-6f55-transmission-solenoid-assembly-original-equipment-fits-07-ford-aa5z-7z369b/

learn task actual transmission parts houses for parts
to see first what is sold or not
the service manual covers this.

It can be shift mechanism issue or its faulty worn out gears.On some cases like these its also seen that problem relates to transmission rebuilt.But that is rare,if these problem is suddenly occurred without any previous problem.To troubleshoot these issue,i suggest you to refer the solved helplinks with appropriate solutions.-----------Click the link below:-----

2007 Sentra; My low beam on my drivers side was not working. i tried 2 different bulbs and same problem persist. I just replaced my fuse under the hood in the black box closest to the windshield. Pull it out slowly and look under the bottom of it and there is a fuses for the left and rt high beams and a fuses for left and rt low beams. good luck

Open hood. on top of headlight assembly you will find 2 small bolts. I believe a 10mm. socket should fit. Take the 2 bolts, out and remove complete assembly.

when you look at the side of the Transmission not positive wich side it is on on the Toyotas but you will see 2 plugs and you should notice them right away. and pull out the one in the most upper portion of the tranny. make sure your on level ground also. The plugs will look like bolt heads that are not holding any thing to the transmission

91 through 96 should work
