Thank you all once again! I had a good friend's and coworker's father who is a GMC trained transmission specialist, along with two other mechanics, one a hybrid specialist, all come after a fifteen hour drive from where I live on the Oaxacan coast. They took things apart, checked everything, and determined that it was a drive motor, I believe attached to the transmission. They were able to make it work and get the car running (after three months sitting in my drive). We only paid their gas and food while they were here one afternoon, a great kindness. We asked them to take the car to where they live where it will be sellable. It's a shame because we loved the car, but there's no one here that knows anything about the hybrids, and this was the second time it's been out of commission for a few months at a time while we tried to figure it out. They'll sell and give us the whole amount of the sale, refusing the percentage that we offered them. Now we have to buy an lesser car, but one that can be fixed when necessary. Your comments and attachments were very helpful!
