High-Mileage Transmission Claim Rates (250k+)

Matched claim rates step up slightly at very high **purchase mileage**: **under 80k ~10.0%** vs **250k+ ~14.8%** in analyzed orders (**n = 2,421** in band cross-ref). High-mile buyers still face the same **first-500-mile setup** risks as any install.

| Odometer at purchase | Matched claim rate (approx.) | |----------------------|------------------------------| | **Under 80,000 mi** | **10.0%** | | Middle bands (80k–249k) | ~11–13% | | **250,000 mi and above** | **14.8%** |

Analysis cohort: **n = 2,421** matched orders in export cross-ref.

| Factor | Pattern | |--------|---------| | Work use | F-250/F-350 and HD Silverado often ordered at **200k–250k+** | | Economics | Reman at high miles beats repeated field repair | | Vehicle retention | Chassis kept for revenue miles |

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

> Before any unit is removed or replaced, document the symptom, save scan results or inspection notes, and contact support with the installation details so the issue can be reviewed accurately.
