Explain duty cycle and warning messages
Describe short trips, extended idling, loaded miles and any recent changes in use. Copy the exact warning message and share available codes or prior test results. A code can point testing in a useful direction without identifying a failed part by itself. Disclose modifications so the team can assess the requested job accurately.
Transfer the records with the truck
If another facility has already inspected the vehicle, request the findings and work authorization history. Arrange release and transportation with that facility, then confirm Bonham intake. Keep towing arrangements, diagnostic authorization and the repair estimate separate. Do not move a truck based only on an assumed completion date.
Bring a diesel concern—not an assumed parts list
- Provide the engine family, mileage and any exact warning or reduced-power messages. Note towing load, idle time and the conditions when the fault appears.
- Share fuel-system, exhaust-system and diagnostic history, including codes already recorded. Codes guide testing; they do not prove which component failed.
- Confirm the requested engine and job scope before transport. Ask which tests are initially authorized and when the advisor will report findings or the need for further testing.
Our service approach
Fast answers. Clear updates. Work you approve.
Ask about Bonham’s same-day diagnosis program before arranging drop-off. Availability depends on arrival time, technician availability, the concern and the testing required. An intermittent fault can need additional testing. Diagnosis and completed repair have separate timelines.
- 01
Agree on the first step
Describe the problem and agree on the initial diagnostic authorization. Give us the best contact and any fleet approval requirements.
- 02
Understand the findings
Ask what the testing established, what remains uncertain and what work is recommended. Separate the original concern from other maintenance needs.
- 03
Approve the repair plan
Review the estimate, parts availability and expected next update. Additional testing or work requires a clear conversation about scope and authorization.
Our aim is to identify the cause, explain the options and get the repair right. A parts replacement is not a substitute for a diagnostic plan. Call (903) 583-8877 to discuss the vehicle before making an out-of-town trip.

Questions before your next step
Can I ask about Power Stroke or Duramax repair?
Yes. Share the exact engine, vehicle and concern so Bonham can confirm the work and appointment scope. Manufacturer warranty administration is a separate question.
Is same-day diagnosis guaranteed?
No. Ask about current availability. Arrival time, technician capacity, the concern and required testing affect the diagnostic timeline.
Does same-day diagnosis mean same-day repair?
No. Parts, further testing and authorization can affect completion. Ask for the next update and a repair estimate based on the findings.
Is the repair facility in McKinney?
No. The service location is Bonham Chrysler, 2122 N Center St, Bonham, Texas. Confirm intake before traveling or arranging transport.
Will repairs be completed without approval?
Discuss the initial authorization and how additional work will be presented. Review the estimate and approve the agreed repair scope.
