PWR LIGHT FLASHING CONTINIOUSLY

the operators guide states
read it
if the hold light flashes there are transmission problems.
get it serviced.
and goes to limhome mode.
the FSM (buy one) covers what do to if handy DIY and with tools.

Take it to the honda garage. Engine light could be anything. D light flashing is the transmission pressure switch.

done at home and engine lights flashing indicates that wires for the transmission have not been connect or connected correctly
engine light also reports on transmission problems and the first cause is wiring
from there get a fault code reading to get what servo/' solenoid or sensor is faulty

Try adding water absorb ant fluidd, ie heat. To fuel. May have condensed water in tank. Popped a fuse or breaker

Hi Slilbit, Take the vehicle for a diagnostic scan. The flashing light is indicating a problem with the transmission. Regards John

If the D4 light is flashing, you have a transmission control failure and you need to get your transmission and transmission control system checked out.

Hope this helps

could be alternator light

the flashing "D" indicates a problem with transmission. i believe honda has an extended warranty for this transmission. is it over 100k miles?

I am very excited because I have the same problem and thought it was transmission but went to my mechanic today and he found that some computers were giving codes on my car. One computer module is under Right Passenger seat, turn key on but do not start car and read how many times that light flashes, then ask mechanice to tell you what the code means. In my case what is causing the tranny to slip is the need for a new speed sensor control module. So, you may just need one of those too instead of a new tranny. !!!! Since my Legend was flashing a code 15, my mechanic pulled the fuse that you are supposed to pull when this 15 code comes up and hold it out of fuel box for 10 seconds and then put it back in. This reset the computer and then it showed no code, (no flashing light.) He told me to drive it for awhile and then check again to see if a code was flashing. If nothing flashes then you are OK. If it does flash, count number of times it flashes and tell the mechanic. If the light flashes, it means it is a "code". If it flashes 15 times it is a speed control sensor messing up the transmission capability and just needs the speed control sensor replaced!!
He also checked a computer under the rug of the passenger side dashboard under the glove box. It was flashing a 2, (2X). He pulled the fuse that corresponds to that and held it out for 10 seconds to reset it, and now it does not flash, ie shows no code, so that is fine. But check those 2 computers on your Acura to see if it is giving you flashing light in either of them, and if so, count how many times it flashes, and then you will know if it is really the transmission.

My car runs a HECK of a lot better now that he reset the codes. I think something got "off" when my alternator was replaced and they had to be reset.

I am thrilled I won't have to replace transmission!!
