what would cause my car not to shift and the speedomoter and odometer to stop? on 2005 Suzuki Forenza

Alright my car stopped shifting and the speedomoter and odometer also stopped as well..at the same time the check engine light came on. i had it diagnosed at a suzuki dealer and they tried a few things but no luck. so they called a tech and they said the only way to fix it is to change the transmission. Now im no mechanic but since the problem goes away once the comp is reset that tells me its probably an electrical problem and im really thinking that changing the transmission is not neccessary. any ideas?

I DON'T KNOW MUCH ABOUT THIS MAKE BUT IT SOUNDS LIKE AN OUTPUT SENSOR. A GOOD SCANNER SHOULD TELL WHAT THE PROBLEM IS.
