Hi G6eTurboDaily, did you end up finding out what was going on? I've had the same issue come up. I was on the highway and went to overtake and it dropped to 3rd gear and had "Transmission Fault" show up on the dash. Once I turned it off, it went away but came on again a couple hours later once I hit 15PSI in 5th gear. I had the gearbox serviced about 3 months ago/5000kms ago, so I don't think it would be that. Just wondering if you found the issue. I'm thinking maybe a torque converter issue?
