Diesel Makes & Engine Platforms We Service
Every platform fails its own way. We know how yours does.
An independent shop — no dealer affiliation — with real experience on the engines and trucks running Central Texas. Every make below has a page on how it actually fails and what we do about it. Pick yours, or call 512-717-2777.
Engines we diagnose from data, not guesswork
The engine decides how a truck fails. Each generation has its own weak points, and knowing them is the difference between a repair and a parts-swap.
Power Stroke
F-250s, F-350s, and Super Duty trucks in for everything from a 7.3L that refuses to quit to a 6.7L pulling a gooseneck every day — Power Stroke work is our bread and butter.
7.3L (1994–2003) · 6.0L (2003–2007) · 6.4L (2008–2010) · 6.7L (2011–present)
See what we fix →Cummins
The engine people buy the truck for. We keep 5.9L and 6.7L Cummins running right — in pickups and in the medium-duty trucks that earn their keep.
5.9L 12v & 24v (1989–2007) · 6.7L (2007.5–present) · Medium-duty Cummins · Cummins in equipment
See what we fix →Duramax
Silverado and Sierra 2500HD and 3500HD trucks — from LB7 injector jobs to L5P emissions work, diagnosed properly and repaired to last.
LB7 (2001–2004) · LLY / LBZ / LMM (2004–2010) · LML (2011–2016) · L5P (2017–present)
See what we fix →Mercedes-Benz diesel
Sprinters, BlueTEC SUVs, and the OM642 V6 that powers both — European diesels need a shop that knows their specific failures.
OM642 (3.0L V6 CDI) · OM651 (2.1L four-cylinder) · BlueTEC / AdBlue models · Sprinter vans
See what we fix →Detroit Diesel
The engine in most of the Cascadias on I-35 — DD13 and DD15 work, plus the Series 60s still earning their keep.
DD13 · DD15 · DD16 · Series 60 (legacy) · 6.2L & 6.5L V8

Class 6 through Class 8, in full-size bays
Highway tractors, vocational trucks, and box trucks — with the lifts, alignment equipment, and air-system tooling the work actually requires.
Peterbilt
Owner-operator pride or a working fleet unit — we service Peterbilt trucks in full-size bays, not a parking lot.
379 & 389 · 567 & 579 · PACCAR MX engines · Cummins-powered Petes
See what we fix →Kenworth
T680s running freight and W900s that have earned their keep — we keep Kenworths on the road and out of the breakdown lane.
T680 · W900 · T880 & vocational · PACCAR MX & Cummins
See what we fix →Freightliner
Cascadias running freight and M2s working local routes — the most common truck on the road, and a regular in our bays.
Cascadia · M2 106 & business class · Detroit DD13 / DD15 · Cummins-powered Freightliners
See what we fix →Volvo
VNLs turning highway miles into revenue — D13 diagnostics, aftertreatment work, and the chassis service that keeps them rolling.
VNL · VNR & vocational · Volvo D11 / D13 · I-Shift transmissions
See what we fix →Mack
Vocational trucks that work for a living — dump, mixer, and refuse Macks get hard use, and we service them accordingly.
Anthem · Granite · Mack MP7 / MP8 · mDRIVE transmissions
See what we fix →International
LTs on the highway and MVs working local — including the older MaxxForce trucks other shops would rather not see.
LT series · MV & DuraStar · International A26 · MaxxForce (DT, 13, 15)
See what we fix →Isuzu
The NPR is the box truck half of Austin runs on. We service Isuzu low cab forward trucks — and we have the room to tilt the cab.
N-Series (NPR, NQR, NRR) · F-Series (FTR, FVR) · 4HK1-TC · 6HK1
See what we fix →Hino
Medium-duty Hinos working local routes — diagnosed by a shop that will actually take them on.
155 & 195 · 268 & 338 · J05E · J08E

The ones other shops turn away
Vans, imports, off-road equipment, and vehicles most shops will not touch. These have service pages rather than make pages, but the work is the same standard.
- Sprinter vansMercedes, Freightliner, and Dodge Sprinters — service, diagnostics, and repair.
- Import & European dieselVW, Audi, BMW, and Mercedes diesel cars and light trucks.
- Heavy equipmentSkid steers, excavators, tractors, and other off-road diesel. We do not service generators.
- HMMWV & military vehiclesHumvees, Hummer H1, M35A2, M939, and LMTV. No demilitarization or weapons work.
- Mercedes Unimog404, 406, 416, 435, U1300L and U500 — OM352/OM366 engines, portal axles, hydraulics.
- EarthRoamerThe Super Duty chassis and 6.7L Power Stroke underneath — not the camper house systems.

One account, every make
Most fleets we service are not brand-loyal — pickups, box trucks, semis, trailers, and equipment across a half-dozen makes. That is normal here, and it is exactly what a fleet account is for: one contact, one invoice, and nobody splitting the fleet across a dealer, a tire shop, and a mobile van.
- Fleet maintenance & managementScheduled maintenance, priority scheduling, fleet pricing, and the option to have us run the whole program.
- Concierge pickup & deliveryA CDL-licensed technician collects your truck and returns it repaired — whatever make it is.
Common questions
Are you a dealer or factory-authorized for any of these makes?
No. Modern Diesel is an independent shop with no dealer affiliation and no manufacturer authorization. We service these makes; we do not represent them. In practice that means nobody is working to a franchise quota, and you can talk to the person who owns the shop.
My make is not listed. Can you still work on it?
Usually yes. The pages here are the makes we see most often and know deeply enough to write about honestly — they are not the limit of what we service. Call 512-717-2777 and describe the vehicle. If it is genuinely outside what we should take on, we will say so rather than learn on your truck.
Do you have the diagnostic software for modern trucks?
Yes — current diagnostic equipment is a standing investment for us, because a modern diesel with an aftertreatment fault cannot be diagnosed with a code reader and a guess. Diagnosis comes first on every job, and you get an estimate before work starts.
Can you do warranty or fleet work across several makes at once?
Mixed fleets are normal here — a single account routinely covers pickups, box trucks, semis, trailers, and equipment across a half-dozen makes, on one invoice with one point of contact. See fleet maintenance and management for how that is set up. Manufacturer warranty work has to go through a franchised dealer; anything we repair is covered by our own warranty terms.
