Anyone ever had a torque flight shift from 1st gear to 3rd only when the car has sat overnight. I have 400 BB and PB torque flight in my ‘63 Polara. The trans has a small shift kit. Even more strange if we drive the car to a cruise or show, and maybe meet friends at a restaurant afterwards, the trans will shift perfectly, it pretty much has to sit at least over night, or several days. Any ideas if this might become an issue, or if anyone has had this problem, input appreciated!
