WHAT COULD I CHECK TO ENSURE THAT MY SPEEDOMETER IS NOT PROPERLY WORKING? wHEN I AM GOING 65, IT IS READING 55. WHAT SHOULD I CHECK FOR. I WAS TOLD TO CHECK THE CABLE GOING TO THE TRANNY AND SEE IF IT WAS LOOSE. i HAVE A 96 CIVIC DX AND RECENTLY DID A TRANNY SWAP AND THINK THAT MIGHT BE PARTS OF THE PROBLEM, LIKE I DIDNT DO SOMETHING RIGHT. PLEASE HELP ME.
