How we selected these businesses

Three is a deliberately small number. It forces us to leave out good companies.

  1. We start with everyone.4 transmission repair shops in Portland, from public listings and review platforms.
  2. We remove the risky.No working phone, too few genuine reviews or a weak rating.
  3. We read the record.Review volume and recency, years in business and the record checks we could confirm.
