Job description

Step into a day in the life You clock in, scan your digital workboard, and line up your priorities: a preventive maintenance inspection with a test drive, a driveline vibration to diagnose, and a telematics unit to program and verify. Before lunch, you’ve traced an intermittent electrical fault to a corroded connector; after lunch, you rebuild a clutch assembly, road-test to confirm shifting is crisp, and log each part and labor hour on your work tablet. You end the day with a spotless bay—tools racked, paperwork complete, and every repair meeting DOT and safety standards.
