I had an check engine light and it was 30 (TCM signal A). Does anyone know what that mean. I have a manual transmission, I thought TCM code is for automatic tranny only.
Could someone point me out what I should look through to get rid of this cel..

95 acura integra 5speed tranny. Motor is rebuild, but tranny is stock LS no swap..

 

Your ECU is from an auto-trans car & it wants to have a signal circuit going to the tranny controller.

 

Now I got it. My ECU is chipped p28 for hondata s100. Could I change some setting on my rom editor to get rid of this cel.

Thank you for replies
