Hi there, hate to hear you're dealing with this. I also have a similar issue, with no recourse so far. I bought an 08 LGT with the 5EAT transmission. Drove it home and immediately started having issues. Wouldn't start, throwing the p0705 code, then it would start, but while driving would throw the code and stop shifting. It's been at the dealer for 3 months. They've changed the valve body, the transmission wiring harness, the TCU, the ECU, the bulkhead wiring harness and now the "body computer" which requires the car being rekeyed, because they're saying the "body computer" claims it's from Australia. They've determined that there's some starter relay that stays energized and won't allow the car to now start. So it went from starting and running sometimes, to now not starting. What I'm going to do is this: if the "body computer" doesn't fix the issue, have them wire in a toggle switch so i can bypass the problem when needed. Good luck. I'd love to hear from anyone else with this issue and how or if you've been able to resolve.
