Thanks Ms Sherbert for your reply.
After placing this post, I went to a local transmission repair shop, and after they removal and inspection the transmission, they said the Torque Convertor needed replacing and based on the burned fluid the system most likely over heated. They recommended replacing the convertor and obtaining a used Main Control Value body and rebuilding it. I decided, while it was out of the Truck, to go ahead and do a complete overhaul. Got the truck out and it ran good for a days. On Friday at about 70 miles an hour it started vibrating, slowed down it was OK for awhile. On Saturday drove the truck about 10 miles round trip, no problems. About an hour later, on second trip the vibration started at about 40 or 50 miles an hour, I pull over to the side of the road, and race the engine, and it didn't appear that the engine was the problem. I'm thinking convertor? But, I have no idea?
