- **Median purchase mileage** and claim patterns across compared cohorts - **Named model examples** with sales volume and mileage bands - Why some applications cluster **earlier or later** in miles - **Reman vs used** or make-comparison context where relevant - What to prepare **before ordering** and document after install ## What Do Miles-Per-Year Bands Show for Claim Rates?
| Usage intensity (mi/yr est.) | Matched claim rate (approx.) | |------------------------------|------------------------------| | Low annual mileage | **~11%** | | Average | **~12%** | | High annual mileage | **~13%** |
Rates cluster tightly — compare **purchase mileage** and **install setup** before assuming fleet use guarantees higher reviews.
How Does Usage Intensity Affect Purchase Timing?
| Driver type | Typical pattern | |-------------|-----------------| | Low mi/yr | Older age, moderate odometer at purchase | | High mi/yr | Higher odometer at younger vehicle age | | Commercial | HD trucks at **200k+** — see F-250 claims: /blog/ford-f250-f350-transmission-claims-20-year-trucks |
What Should High-Usage Owners Document?
| Lever | Transmission | Engine | |-------|--------------|--------| | Fluid / prime | Correct ATF, level, leaks | Oil prime, spec, filter | | Programming | Relearn / TCM | Immobilizer, crank relearn | | Cooling | Cooler flow, lines | Thermostat, bleed, fans | | Documentation | Photos, scan baseline | Timing proof, torque specs |

What Should You Document If Problems Start Soon After Install?
Many transmission warranty reviews involve the **first 500 miles** after install — often fluid, cooler flow, seals, or programming — regardless of pre-replacement mileage.
Before any unit is removed under warranty:
- Odometer photos at delivery and at symptom onset
- Scan tool report (stored and pending codes)
- Fluid type, level, and condition notes
- Install invoice with date and shop name
- Photos of leaks **before** cleanup
