Diesel Engine Emission Troubleshooting

Note: In this video I said the turbo boost sensor has to be replaced.

Allison Automatic Transmission Module

The Allison Automatic transmission module I’m talking about in the video is for a 2500 series model we’re running in all of our newer conventional buses.

School Bus Steering Repair
