I have a transmission he rebuilt in my GP now. I use my GP for delivering newspapers, so lots of stops and starts daily while putting over 100 miles a day on it. I might be getting rid of my GP in a few weeks, so if you want a running coupe for parts, I know where you can find one.
He had a transmission available on the bench, so I didn't have to leave my car with him. I just paid for parts up front for the rebuild, and he contacted me when he was ready to install it.
