Hi Greg,
I have just had this issue with an 8 speed TCS (transmission control switch), my fault code was;
P176C-11 "Transmission Range Selector Lock Control Error - General Electrical Failure - Circuit Short to Ground"
In short, I managed to fix mine and create a work around if it ever fails again, I intend on writing up a quick recovery guide for the 8 speed sticky forum.
Cheers
Marc
