Automatic Transmissions
- Description
- Document
As automatic transmissions have developed, they have decreased in size and their structures are more compact. At the same time the gear count has risen to even as high as 9 gears, and their efficiency has caught up with other transmission types. Due to this, the technicians need to update their knowledge on “traditional” automatic transmissions.
