I've just recently finished putting my '00 Civic Si back to stock to sell it, so far everything is fine, one check engine code, (Primary O2 Sensor needs replacing).

But just recently I noticed that my Speedometer is not working, the tachometer works fine.

Could I have done something to the Speed sensor in the tranny??? Is it a sensitive unit??? (Sensitive meaning if not put back in place properly it will not work, i mean it's only 1 bolt to hold it in, i took it out when i removed my exedy and put the factory back in.

BTW I am noticing VTEC not engaging either.

Any ideas??? I only put 1 qt of Honda tranny fluid in as well, not sure if lack of tranny fluid makes it not give accurate readings.

 

anyone???
