International Truck Repair in Austin, TX
LTs on the highway and MVs working local — including the older MaxxForce trucks other shops would rather not see.
International service at an independent Austin shop
International covers a lot of ground, from current A26-powered highway trucks to MV and DuraStar vocational units and the MaxxForce engines that earned a hard reputation. We take them on, and we tell owners honestly what a given truck is worth putting money into.
International models and drivetrains we service
- LT series — Current highway tractors with A26 power and modern aftertreatment.
- MV & DuraStar — Medium-duty box, service, and vocational trucks on local routes.
- International A26 — Engine diagnostics, aftertreatment faults, and repair on the current platform.
- MaxxForce (DT, 13, 15) — EGR-heavy engines with known emissions problems — diagnosed straight, no false hope.
What we see fail on International
- MaxxForce EGR and emissions failures — The platform's known weak point: EGR coolers, valves, and repeated aftertreatment problems.
- Aftertreatment derates — DPF loading and DEF faults that pull power on a loaded truck.
- Turbo and boost problems — Sticking vanes and leaks that show up first as poor fuel mileage.
- Electrical and sensor faults — Intermittent codes that need live data instead of a parts list.
- Air brake and chassis wear — Brakes, air leaks, and suspension found before a DOT inspection finds them.

Common questions
Will you work on a MaxxForce?
Yes. MaxxForce engines have real, well-documented EGR and emissions weaknesses, and plenty of shops avoid them. We will diagnose yours and give you a straight assessment — including when the honest answer is that the repair costs more than the truck is worth to you.
Do you service International MV and DuraStar box trucks?
Yes — medium-duty Internationals are common in local delivery and service fleets, and we handle their engine work, air brakes, preventive maintenance, and annual DOT inspections.
Can you do the DOT inspection at the same time as repairs?
Yes, and it usually saves a trip. We can perform the annual DOT/FMCSA inspection and handle whatever it turns up in the same visit rather than sending you elsewhere to get it certified.
