When the car is started the dash reads D4 as if it

Posted by philschneide on Nov 07, 2009

This is the standard advice, probably worth following: The "D4" indicator comes on for a few seconds when you turn the ignition ON (II). If it flashes while driving (in any shift position), it indicates a possible problem in the transmission. Avoid rapid acceleration and have the transmission checked by an authorized Honda dealer as soon as possible. Hope this is helpful
