At first incident, the transmission would start slipping causing a vibration while the overdrive was on, the vibration would go away when out of overdrive. Then the car would stall when you would try to take off at a stop, the car would not move until you would turn the car off and crank it again. As you would pull out into traffic the car would not go. Then even with the car out of overdrive while at speeds at 55 mph or higher the transmission would not work, you would have to let off on the accelerator and wait on the rpm's to drop and then it would go into gear again. I took the car to a local mechanic and he advised the trouble was in a solenoid in the transmission. I took the car to a transmission shop, they checked the fluid and said there was water in the transmission fluid, caused by a coolant leak from inside of radiator getting into the transmission lines causing the transmission to go bad due to coolant into the transmission.
