I have a 2001 Dodge Neon with 120,000 miles on it. A few weeks ago, the check eng. light came on. I code checked it and got P0743, TCC solenoid. I did some looking online and saw a lot of people say that it COULD be as simple as removing the connector to the TCC, cleaning it with a plastic safe cleaner and replacing it, making sure it seats well. My question: would this be the correct first step? How can I get to the connector easily without taking half the engine apart? Any other suggestions?
you should be able to get to the connector once under the car. use brake cleaner to get any gunk out of the connector. if that doesnt fix it chances are the solenoid is bad or there is a short in the wiring.
