Peterbilt trucks run Cummins and PACCAR engines, 9-speed or manual transmissions, and complex air brake systems. When your Peterbilt goes down on I-80, you need a mechanic who knows Peterbilt construction inside and out. Call +1 308-270-3596 and we will diagnose and repair your truck on-site.
Peterbilts with Cummins and PACCAR power. Eaton Fuller transmissions. Multi-circuit air brakes. All systems diagnosed with factory tools and repaired on-site.
Cummins ISX and QSX engines. Fuel systems, DEF, EGR, and DPF diagnostics. We know Cummins engine architecture.
PACCAR PX engines are Peterbilt-engineered diesel power. Turbo systems, fuel injection, aftertreatment systems.
The Eaton Fuller 9-speed and 10-speed are standard in modern Peterbilts. Shifting issues, synchronizer wear, solenoid faults.
Multi-circuit air brakes, proportional modulation, trailer control. We test and repair all air system components.
DPF, SCR, DEF, and EGR systems. Complex Peterbilt emission control requires specialized diagnostics.
Peterbilt electrical systems are integrated. Alternators, starters, wiring, and control modules all tested and repaired.
Peterbilt trucks are built for longevity and owner pride. They run some of the best engines and transmissions available. Cummins ISX engines are bulletproof with proper maintenance. PACCAR engines are Peterbilt's own design, optimized for their chassis. The Eaton Fuller transmission is nearly indestructible with correct operation.
But when a Peterbilt goes down on I-80, the complexity works against you unless you have the right expertise. The 9-speed transmission has synchronizers and air shift solenoids. The Cummins engine runs DEF and SCR. The air brake system is multi-circuit and proportional. A diagnostic scan tool is essential.
Call +1 308-270-3596 and describe the fault or symptom. We will come to you with the right tools and fix it on the road.
Modern Peterbilts run Cummins ISX/QSX engines or PACCAR PX engines. Both are Class 8 diesel engines common on I-80. We service both engine families.
Yes. The Eaton Fuller 9-speed is standard in many Peterbilts. We diagnose shifting issues, synchronizer problems, and air shift solenoid faults.
Peterbilts with Cummins engines face DEF system faults and fuel sensor issues. Those with PACCAR engines may have turbo or wastegate problems. Both are common on heavy-use trucks.
$300–$1,000 for most mobile calls. Engine diagnostics, transmission work, and air brake repairs can run higher. We provide upfront quotes.
Yes. We service older Peterbilts with Cummins, Cat, and Volvo engines. Mechanical and electronic systems. Call and tell us the year and engine.
