Wrench light most likely culprits. Details follow

Asked by Diggsies Feb 13, 2022 at 10:35 PM about the 2007 Ford Freestar S

Question type: Maintenance & Repair

2007 Ford freestar 3.9  I don't know the trim so I
selected "S". The wrench light came on last night. It
was a cold, wet night. First time it ever happened. The
van sounds good and the only thing noticable aside
from the light is a rough shift after the light comes on.
Restarting the van turns light off. Upon restart no
rough shift until light comes on after approximately 3
minutes at 55mph.
Pcm is dry as a bone with zero corrosion. Same for
fuse box. No lose or damaged wires or connectors.
I really need to know the most likely culprits. I don't
have hundreds to pay for diagnostics and shops
guessing at parts. I am fairly mechanically inclined
and can swap almost any part with a little information.
The internet tells me no codes would show up on the
scanner at AutoZone but you can't trust everything you
see. I need help. It's our only vehicle. Injured at work
awaiting surgery so finances are not good. 4 kids, 2
are special needs, and one on the way.
Can I drive it without destroying it?
Stuck like chuck.
Thank you so much

I should add this: It is the wrench in the lower left corner, powertrain light, not check engine light. Also, lately, past couple of months, cruise control may work without issues for days or weeks but will occasionally; not turn on, may switch off during the drive, may increase speed approximately 3-5 mph then turn off. It may not be related but who knows. Thought you should know. Throttle body because of unprompted acceleration? I don't care about the cruise unless it's related. I don't use it much. I'm a very responsible CDL class a driver so I know better than to rely on cruise.
