S3 light flashing on my 93 DA
 

I recently purchased a 93 DA integra automatic.. I noticed that when I would get around 15-20mph the S3 light would start flashing and it wont go into overdrive, and the button on the shifter does nothing either. The car shifts real smooth and all that but when Im going 65-70 im almost at 4grand on the tach. I was told that the trans modual could be the issue so I replaced that and it didnt fix the issue.. If anyone has had this issue and knows how to fix it I would really appreciate the info.. Thanks

Probably a valve problem in the transmission. You've checked the trans fluid level already I assume, and has the fluid been changed anytime in the distant past? Those are both cheap and easy things to look at..
