The Lemon Index
Transmission complaints owners filed with the U.S. government (NHTSA) for each model year, per 100,000 cars sold. A complaint counts when it's filed under the transmission, or under the power train and the owner describes the transmission (shifting, slipping, gears, CVT). It's an owner's report, not a confirmed defect, and older years have had longer to collect complaints.
