Check engine light on, code PO741?

What is your question?

I have a Honda Civic coupe lx 2005. Automatic. The check engine light came on after taking it for a drive. I took the nearest auto zone to get the code scanned. It turned out to be P0741. The car runs fine. It got a transmission fluid change recently. So the light did come on after taking it for a high speed drive. Not sure what could be causing the problem.

How long has your 2005 Honda Civic had this problem?
