JDM 93 Toyota Previa 4WD Automatic Transmission 2.4L How Many Miles Do The Transmission Have? We don’t know exactly how many miles each transmission has; however, we have been to Japan and seen that most cars have a mileage around 50-60 thousands miles. It is very rare to see a car that has a mileage over 80,000 miles. Therefore our average mileage for each engine approximately 60,000 miles. Why Do Japanese Engines Have Lower Mileage? Japanese people rely mostly on public transportation such as train and bus. Taxes are higher for older vehicles and bi-annual car inspections can be costly for a person. These are some reasons as to why Japanese people do not like to keep older cars. Payment must be received within 2 days after the auction has ended.
