Diagnostics First, Parts Second

Ask any fleet maintenance manager what is undermining AMT uptime, and the usual answers surface quickly: parts availability, the technician shortage or the right-to-repair debate in Washington.

However, Eaton’s Jason Denardo and Leah Bogle argue that the more consequential damage often happens in the first five minutes after a truck goes down.

In the new RoadSigns Extended Cut, Diagnostics First, Parts Second, Denardo, a senior product manager at Eaton, says the biggest mistake technicians make on automated manual transmissions is replacing parts before completing a proper diagnostic. It may look productive in the moment. More often, it turns a two-hour repair into a two-day disruption.

Inside the full report, Denardo and Bogle explain:

• Why chasing parts can costs shops more time than it saves
• The documentation practice that protects fleets on warranty and liability questions
• Why the technician shortage makes training more essential, not less
• The single no-cost, 30-day adjustment that can meaningfully reduce downtime

For teams focused on reducing downtime, this free report offers practical insight that can save valuable hours on the shop floor.
