Flashing D4 light and TCS light on - 2001 Accord
 

When the car is cold in the morning and I first start out the car shifts hard into 2nd gear and the D4 light flashes and the TCS light is lit. When it warms up and I shut the car off and restart it everything is fine.

Can anybody help?

Have AutoZone or someplace like that read the error code - get the number; it's something like P1234.

I suspect that you'll only get the transmission error. You might have to go to the dealer to scan for the TCS error(s).

What would cause the D4 light to not come on at all? The other shift lights work fine with no flashing.

His flashes, yours doesn't come on at all? Sounds like a different problem.

Maybe a burned-out lamp? If not, you ought to make a new thread, because it isn't the same as this thread.

Yep it doesn't come on at all. Even after turning the ignition key all the way or when the car is driving. I just noticed it yesterday.

faulty light displays around D4 gear and sometimes others - you should get the guys to check your inhibitor switch may need cleaning up or replacing. if its flashing around d4 - tranny check light get a diagnostic test done.
