Preventive Maintenance Programs
Scheduled PM that catches failures before they strand a driver. We build the cadence around your fleet's mileage, hours, or calendar — and we keep the records that hold up under DOT inspection.

Why fleets and drivers choose T&T
Cadence per unit, not per fleet
An older truck running long hauls needs a different cadence than a five-year-old day-cab on regional work. We build the schedule per truck.
DOT-ready inspection notes
Every PM produces a documented inspection — brake measurements, lighting, structural notes — emailed to your ops inbox within 24 hours.
We see issues before you do
Trend lines per unit (Fullbay tracks our work history) tell us when a truck is showing wear you haven't noticed yet. We surface it instead of waiting for the next failure.

Frequently asked
- How often should my truck come in for PM?
- Standard heavy-duty intervals run on a schedule of A (basic — oil, lights, tires, lube), B (A + filters, brake check), and C (B + driveline, deeper inspection). Mileage triggers vary by engine and duty cycle. We'll set the cadence per unit when you start.
- Do you handle the federal annual inspection?
- We perform the inspection work; depending on what your jurisdiction requires for the actual signed certification, we may handle it directly or coordinate with a qualified inspector. Call us with your situation and we'll tell you straight.
- What's the difference between A, B, and C service?
- A is the routine — oil, lube, lights, tires. B adds the filters and a deeper brake check. C is the most thorough — driveline service, hub seals, in-depth inspection. Most fleets run As frequently and B/C on annual or mileage triggers.
- Can you bill PM to a corporate account?
- Yes. Direct-bill accounts on 30-day terms. We set up the P.O. process up-front so PM invoicing is clean and predictable.
- Do you handle fluid analysis?
- We pull samples and send them to an analysis lab on request. Trend data on engine oil and coolant tells you a lot about what's coming — useful for pre-purchase decisions and high-hour fleet trucks.
