1989 Buick Skylark mileage: 73,000. After driving car for short period of time transmission stalls engine out and car will not move until after it sits with engine off for a half an hour to an hour. Transmission seems to be locking up. Engine will run in park or neutral. What could it be?

Your car has a lock-up torque converter in the transmission. It locks-up only in high gear. It is supposed to disengage at lower speeds. Yours is not disengaging. There is probably a valve in the transmission “hanging up” Having the transmission serviced with new fluid may help the problem. Next step, the valve body will have to be removed and cleaned.
