Hmmm, I did some googling on OBDII codes, and I can't find those listed anywhere. [img]style_emoticons/<#EMO_DIR#>/headscratch.gif[/img]

not sure bout fford, but most makes p27xx codes have something to do with the torque converter.

Is your car an automatic?
(p2770 code usually means you have a TCC solenoid that has gone bad or wire pinched/cut)

If you dont have an automatic, then thats an issue. Cars throwing pcm codes that dont exist is usually a sign of the ecm/pcm going/gone bad.

EDIT: try resetting them and see if they come back at all

It's a manual. I googled them and found something about automatics, so that was weird. I reloaded my tune and it went away and hasn't come back.

P2770 Torque Converter Clutch Circuit High
P2771 Four Wheel Drive (4WD) Low Switch Circuit
P2772 Four Wheel Drive (4WD) Low Switch Circuit Range/Performance


Interesting, Ford is making the Mustang in a 4WD version now. Hopefully your reloading of you tune gets rid of it.
