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
