Just chiming in: I just had the same error.
Wrench was NOT present when I dropped it off. Annoyingly it disappeared on the drive there. They had already seen the code in the 'connected' information that the car uploads to the cloud and seemed happy with that.
They replaced the module and said...
Ok, got my 2024 Lariat back (4 hours)
"WRENCH LIGHT CAME ON, FOUND CODE P0929"
"7001D4 MODULE - GEARSHIFT (GSM) - REPLACE
(7210/7D443/7P155) - L
99819 WF"
Apparently there was an issue with a bad batch of gear shift modules
Also joined this club.
2024 F-150 Lightning Lariat ER.
800 miles.
Got the "Powertrain malfunction / Reduced power message" just after turning it on. Had charged to 90% before that. No updates recently.
Guess I'll get a service appointment at the dealer that sold it to me and PM @Ford Motor...
