I am trying to figure out why I am not getting any codes when I jump my service conector. My CEL light comes on when I put the car in drive and it stays solid, and my D4 light blinks. My speedo and my odo don't work. It seems to be runnig in back up mode.

 

How does the car run? I had the same problem except i was doing 10mph at 6000 rpm, friction plate was shot. I dumped my auto and got a manual out of an accord, thats me tho. A little more insight might help. In worst case take it to honda and have them take a look. Pretty penny but worth it "sometimes" i say again "SOMETIMES".

 

The car runs pretty good if you shift manually.. Did the manual Bolt up Ecko, or did you modify??
