maydog Posted June 26, 2005 Report Share Posted June 26, 2005 Greetings, Today a nice couple purchased my 97 STS. I told them about all the work I have done in fixing things up and how road worthy it is. They asked about the trans and I said it was pretty much bulletproof. An hour later I get a call and they said the trans overheat message cam on and they stopped. They drove again after a few minuted and it came back. A third time the trans lost 4th gear. I am no jerk and agreed to take the car back to look at it. I met up with them, gave them back their money, took the title and limped it home in 3 going 45 on the interstate. I drove 30 miles without overheat. I tried to shift into 4th a few times, it would only engage downhill. As soon as the load was increased it would go back into third. I checked the trans fluid, it was full and did not smell burnt. There is a code 218 stored. I had replaced the radiator on the car a week ago and have only done short trips (15) since. What would happen if the trans cooler became plugged? Could this be the issue? Or does it sound like a shift solenoid thing? Please help. Link to comment Share on other sites More sharing options...
