E-350 Superduty Transmission Codes

For the last few years, I have built out the interior of a box truck to a tiny home, I left working on the truck itself for later since I needed a home.

Of many other repairs, one of them involves the transmission.

I have a 2006 E-350 super duty, 5.4L Triton V8 with a 5 speed auto.

It is throwing two codes:
P2701: intermittently stuck Overdrive solenoid
P0756: solenoid B stuck off.
(These are what I found online for the codes, can someone verify?)

I want to attempt to complete the work myself since I also need a new trans gasket and I hope replacing the solenoids is simple enough.
I don't know what I am doing tbh, I'd love help with diagnosis, and the locations of those specific solenoids in trans.

I show P2701 as clutch apply time for the overdrive clutch. That could be a solenoid problem. It could also be a clutch problem.
P0756 is overdrive clutch solenoid performance/stuck off. That is a bad solenoid. Replace it.

Thank you! I will report back when the snow subsides and I can do the replacement.

How should I go about finding a replacement solenoid? I've spent a few minutes looking on various sites to no avail. Are solenoids relatively standard across Ford MoCo Transmissions?

No, they are NOT standard across transmissions.

Try Transtar1.com for parts.
