Just thought I would throw this little write up in here. No pics, but everything is easily visible. This procedure wasn't in the FSM. Took me an hourish trying to find the right combo of extensions and wobbly joints that would work and I needed none of them. Should take 20min with this guide
The parking brake release valve/switch is right above the column on the shift rod next to the firewall. It is white and crescent shaped. It is the typical failure mode for the automatic parking brake release system, assuming you don't have other vacuum issues.
PN is E45Y-2B623-AA and was made as late as 2007 going by the part I bought on Ebay. This is going by Motorcraft/Ford production, I don't like using repop parts as they never fit as nice. I bought mine a week ago on Ebay for $18 so they are affordable.
Note that earlier ones may use the A rev as opposed to the AA rev. I think this was a change in the adjustment slots so that it only releases the brake in forward gears as per my later edition of the Service Manual. My EVTM is earlier and says the brake should release in Reverse, this is not possible unless you modify the slots on the AA rev valve.
Remove the vacuum hoses on the valve, the supply hose from the firewall goes to the smaller port, they should be pokey oked unless someone has replaced a hose with generic hose.
Keep the vehicle in park for now.
Remove the 2 screws holding the valve to the column/shift rod/bracket. They are a 1/4" head, not metric, very shallow heads. The lower one is easy to get to, the top one is on the top left corner, a bit challenging to get to. I was able to get both with a 1/4 drive ratchet and standard height socket.
With the screws off the valve can be removed.
The new valve should have a red indexing pin sticking out of it. Looks sort of like a golf tee. This pin holds the valve at it's release point. Do not remove it yet.
Set your parking brake and shift the vehicle into OD, or whichever forward gear you want the brake to release in (might be able to work it in Neutral if you want to)
Shut the vehicle off
The valve has a socket on the back that will slide over the pin that is now visible with the old valve removed. This is what actually moves the valve. It is attached to the shift rod and rotates as gears are shifted. If this is unclear, look at where the valve was installed and shift through a couple gears.
Slide the new valve onto this pin without removing the red indexing pin. The screw holes on the bracket should line up somewhere in the 2 slots now.
Put the 2 screws back in and snug them down.
Remove the red indexing pin only once the screws are tight.
If you need to realign the valve, loosen the screws and shift the vehicle into whatever gear you want as the release. Now slide the valve along the slots until the hole at the top is open and the red pin can be reinserted
(you should have a mirror on a stick for this) Then retighten the screws.
A mirror on a stick can also be used to verify that the shift pin is actually in the slot and not stuck on either side of the socket.
Plug the hoses onto the ports, supply from firewall to the smaller diameter port.
Start the vehicle and check for function.
