Thanks for the reply A-series,
The light that keeps coming on is the green "S" light. The problem I have is when I start the car the "S" light comes on (I don’t use the button that you press on the shifter for Sport Mode) and stays on for a few minutes then it goes off. Sometime the light will come on for a few minutes while I am driving. When the light comes on, I have the shifting issues (1st and 4th gears don’t work). When the light goes off, everything runs normal. By the way, I have never had the D3 or D4 warning lights blink.

I found this link online (http://en.allexperts.com/q/Honda-Rep...t-properly.htm) with someone else having the same problem, but I didn’t want to replace the TCU, if it isn’t the problem. I just wanted someone else's option.

ANY HELP OR OPINIONS WOULD BE GREAT.
THANKS!
