This issue is caused by a transmission fault or malfunction, most likely a shift solenoid in the trans has failed or the trans control module has a problem, the trans can be tested for codes that will show what circuit or component of the trans controls is causing the light to stay blinking, have it tested.

check the shift solenoids by using a OHM METER .the both solenoid connectors has 2 terminals 1 and 2 .take ohm meter measure terminal 1 resistance to body ground it should be 14-30 ohms.if less or more replace it.then number 2 terminal to ground.do both the connectors that you disconnect.they should be 14-30 ohms.if less or more replace them.if they check out good .your valve body in transmission is going have to be removed.

Has anyone change the transmission fluid and used anything other than Honda ATF-Z1. If so, have the fluid/filter changed in this car and use only Honda Fluid. This is the only fluid that you can use in a Honda. Even if you have used the correct fluid an fluid/filter change may help. If that is not the case then I suggest you seek out a trusted professional.

The d is for drive, the number is for what gear you are using.Driving in 3rd gear all of the time will decrease gas mileage, and increase engine wear, but as long as the engine rpms aren`t too high there is no immediate damage.
