The skills gap (what you need to learn)
Be honest about civilian skills you don't have:
Customer service and communication: Working at a dealership means explaining repairs to customers who don't understand mechanical systems. You'll need to translate technical issues into plain English and provide cost estimates—very different from military maintenance.
Computer-based diagnostic systems: Civilian equipment uses manufacturer-specific diagnostic software (CAT ET, Komatsu KOMTRAX, etc.). You'll need to learn these systems—they're more advanced than military diagnostic tools but based on similar principles.
Flat-rate or billable hours: Some shops pay on flat-rate (you get paid based on job completion, not hours worked). This rewards efficiency but creates pressure. Understand the pay structure before accepting positions.
Business operations: If you go independent (mobile mechanic, small shop), you need to understand invoicing, insurance, tax withholding, and business licensing. Take small business courses or partner with someone who handles admin.
Civilian workplace culture: Military directness doesn't always work in civilian shops. You may encounter less motivated coworkers, different safety standards, and less structured environments. Adapt your communication style and lead by example.
