Do you work on Volvo VNL and VNR trucks?

Yes. We service Volvo VNL, VNR, VHD, and VAH trucks with D11 and D13 engines and I-Shift transmissions: diagnostics, aftertreatment, brakes, cooling, electrical, and preventive maintenance.

Can you diagnose an I-Shift problem on-site?

Yes. The service truck carries the diagnostic tooling to read I-Shift fault data and live values. Sensor, selector, and fluid issues are handled on-site; internal transmission work is a shop job.

How quickly can you respond to a Volvo breakdown?

Call (918) 925-9356 any time; emergency response is available 24/7 and the ETA depends on where you are within our 120-mile service area.

Do you do DOT inspections on Volvo trucks?

Yes. We perform DOT annual inspections and preventive maintenance on Volvo trucks at your yard, and combine both in one visit when possible.

Common Volvo Trucks Repair Issues We Fix

Aftertreatment and DEF system faults

D11 and D13 engines log SCR efficiency, NOx sensor, and DEF quality faults that lead to inducement derates. Reading the aftertreatment data before replacing parts avoids chasing the wrong sensor.

DEF or aftertreatment warning
Regen requests more often than usual
Derate warnings or 5-mph inducement
Excess white exhaust

I-Shift transmission concerns

Most I-Shift complaints are sensors, the gear-selector module, clutch wear, or a fluid issue rather than a failed gearbox. Live data and a clutch check come before any talk of replacement.

Gear-selection faults on the dash
Slow or harsh shifts
Clutch slip on grades
Transmission stuck in neutral

Electrical and multiplex faults

Volvo trucks use a multiplexed body-control system, so a chafed harness or corroded ground can produce faults across several modules at once. Voltage-drop testing and a CAN check find the physical cause.

Multiple modules logging codes
Intermittent dash warnings
Lighting or accessory faults
Battery drain when parked

Cooling, EGR, and charge-air issues

EGR cooler leaks, fan clutch faults, and charge-air cooler leaks cause overheating and power loss, especially in Oklahoma summer heat. Pressure and leak tests confirm the source before parts are ordered.

Overheating under load
Coolant loss with no drip
Low power and high exhaust temperature
Turbo boost faults
