Hey yall I came here because a friend said yall can help me. My check engine light came on so I ran the code and it was a solenoid shift one so I cleaned out the solenoid flushed the fluid and it was good for about 3 months then it came on again for the same reason so this time I replaced it and flushed it and it was good… then a week later the engine light came right back on for the same reason. Is my transmission cooked or is there still saving it?
