Allison 3000 transmission problem solved
« on: August 28, 2024, 07:33:49 PM »
Recently we developed a speed sensor code of po 7-21. We called Allison and they showed me how to clear the code and it work for about 100 miles. Then the code resurfaced. A local Allison dealer reminded me it could be a bad speed sensor or wiring on the sensor. I unplugged the sensor and reinsert the plug and was able to safely drive to the Allison dealer and avoid a tow
