Open 24 / 7Questions truckers ask us
Do you offer 24/7 truck repair in Oklahoma City?
Yes. Diesel Truck Repair LLC runs 24/7/365 emergency roadside assistance across the OKC metro, plus a full-service shop on the West I-40 Service Road open Mon–Fri 8am–6pm and weekends by appointment. Call 405-475-2735 any hour.
How fast can you get a mobile diesel mechanic to me?
Typically 30–90 minutes anywhere in the Oklahoma City metro, including the I-40, I-35, and I-44 corridors. One call gets a fully equipped service truck and an ASE Master Certified tech moving toward you.
How much does semi truck repair cost in OKC?
It depends on the problem — a roadside fix and a full engine rebuild are very different jobs — so we diagnose first and quote before we wrench. Every repair is warrantied, and if money is tight, repair financing is available through truckrepaircredit.com so you can get rolling now.
What truck makes and engines do you work on?
All major makes, from medium-duty pickups to heavy-duty semis, trailers, RVs, and equipment. We specialize in CAT, Cummins, and Detroit engines, run dealership diagnostic software, and use quality parts from Eaton and Meritor.
Are you the same company as The Truck Doctor?
Diesel Truck Repair LLC is the next chapter of the shop OKC knew as The Truck Doctor — same location on the West I-40 Service Road, same phone number, and the same 35+ years of experience behind every repair.
Do you offer fleet maintenance programs?
Yes. We build custom preventive maintenance schedules for fleets in the OKC metro, handle DOT inspections, and offer fleet service discounts. Call 405-475-2735 or use our appointment form to set up an account.
