Introduction
Transmissions are a core component of a vehicle and are manufactured in-house by OEMs or by a limited number of specialized manufacturers due to their large number of parts and complex assembly.
The ATs (automatic transmissions) presented in this report are basically stepped transmissions that combine a torque converter and a planetary gearbox, but also include the following configurations that do not have either of these.
- Power transmitted by a multi-disc clutch or motor instead of a torque converter
- Two-shaft gearbox used instead of a planetary stage, combined with a torque converter
- The above 1 is an "AT-based" structure, as shown in the green box in Figure 1 below, which is often used for hybrids, but Mercedes-Benz has been using multi-disc clutches in ICE (internal combustion engine) vehicles for many years, and Mazda has been using them from 2022 onwards.
On the other hand, the sub-transmission associated with the lower stage of AWD or CVT (continuously variable transmission), the final reduction gear installed on the axle, and the gearbox used for power taken out of the vehicle (PTO) are not included, regardless of the type.
