Hi AllisonMan, We just had the computer fail on the MD3060. Fortunately I was just leaving home to get my tire balance corrected and so returned home and had to have it towed to the shop. Haven't gotten the exact price yet but just the computer/display apparently will be $1000-$1500. I'm told that Allison doesn't rebuild so my question is anyone else rebuilding? Or is there a source for used ones?
