The Silverado Code App

The Silverado Code App puts a mechanic's checklist in your pocket for the moment your truck does something weird: a tick on a cold start, a shudder at 45 mph, a light on the dash.

Tap "Something's wrong", answer a few quick questions, and get a clear verdict: Keep an eye on it, Book it this week, or Stop driving, with the reason and the next step.

INSIDE THE APP

- Something's wrong: triage by what you hear, feel or see

- Code lookup: the common Silverado codes, what they point to and how fast to act

- Maintenance tracker: what's due by mileage, normal or towing schedule

- My truck card: engine code, oil spec, transmission fluid, tire pressure

- Shop counter helper: reported price ranges and the questions to ask

- Cold-start listen log, monthly 10-minute check, recall check

- 89 short guides for 2007 to 2025 Silverado 1500s (GMT900, K2XX, T1XX)
