P1762 Direct Drive Solinoid. When I crank the car for the first time of the day it shifts like a brand new car but after about 8 miles it goes crazy and it will stay in a high gear and sometimes when you come to a stop and if it down shifts it feels like someone rear-ends me and sometimes it feels like I'm riding my brakes but then I turn it off for about an hour and it drives like new again. Can someone Shedd some light on the subject please
