Thanks again for the help Max, I really appreciate it. There is no shipping cost on the $600 unit as it is local to me. I am not sure either that the trans is bad, but that is what the shop has told me. They said it wasn't the linkage, and it wasn't the speed sensor, not sure what else I can try. Any suggestions for things I can try on my own? Indeed, the issue is that the car will not upshift.
