I have a 91 Honda accord ex with a blinking s light and tcu code 7. I know the codes for shift solenoid A. The light was blinking before and the car would only shift between 2nd and 3rd gear when in D3 or D4. I had this problem for awhile but thought I fixed it when I put a new shift solenoid on it. The shift solenoid solved the problem for about 2 weeks and now the light is blinking again and has code 7 for the shift solenoid A.

Anyone have any advice? I'm thinking the tcu has a problem or maybe I have a bad connection at somewhere. I havnt had time to check it good connections yet but will probably be checking it tonight or tommorow
