I have a 1999 accord with the auto trans, all was good till I took the battery loose to install some glow gauges not the trans is acting up taking long time to shift gears and at times shifting hard. The D4 light is (not flashing) any idea's welcome.

 

get it diagnosed and if it is the trans replace it with a HONDA REMAN....too many updates to the unit to trust a trans shop rebuild it properly....

 

before you spend money taken it to a shop check the fluid level. also if it needs fluid make sure to use honda z1 atf

 

yee drain and refill the fluid and reset the ecu and let it idle for 10mins.
