I have a 1999 Honda Accord that i just put a JDM Transmission in and when i go like 40 MPH or higher the speedometer is reading like 10 MPH faster then what i am doing. I went through a school zone and it seemed ok at 30 MPH or less.....(Speed reading sign)...Any ideas???\

Possible Wrong differential
hook it up to a scanner and drive it as you compare the scanner speed to cluster reading what you have ?

Also try and use old sensors from the old tranny

I did switch the sensors. What kind of scanner are you talking about?
