Why fleets and drivers choose T&T
Real diagnostic time before tear-down
We chase root cause first. You won't pay for a parts replacement that didn't fix the problem because we didn't know what the problem was.
Parts inventory built for repeat customers
Our parts manager keeps the fast-movers on the shelf. Fewer 'waiting on parts' calls, faster turnaround on the work that matters.
Estimate before work — never a surprise
You see the number before we start. If something else turns up mid-job, we call before we touch it.

Frequently asked
- How long will a major repair take?
- Depends on the work. A clutch job is a day or two; an engine in-frame is a week or more. We'll give you a real timeline before work starts and update you if anything shifts.
- Can I bring my own parts?
- Yes, with a couple of caveats. We can't warranty parts you supply, and if a customer-supplied part fails or doesn't fit, we charge for the additional time. For most fleet customers it's cheaper to let us source.
- Do you offer fleet billing for shop work?
- Yes. Direct-bill accounts with 30-day terms once we've set up the account and a P.O. process. Get the paperwork done before the breakdown — it makes the urgent calls faster.
- What if my truck won't run? Can you tow it in?
- We'll coordinate the tow with a trusted partner. We don't run our own tow truck, but we'll get you to the right place and start the work as soon as it lands.
- Do you work on light-duty or just heavy-duty?
- Class 7 and 8 is the focus. Medium-duty box trucks and service trucks — yes. Pickups and personal vehicles — no, that's not what our shop is set up for.
