Circuit Description
WARNING: This page is about a different car, the 2005 Suzuki Reno and 2005 Suzuki Forenza. However, it is still accessible from the selected car via links, so may be relevant.
The special feature of 4HP 16 Automatic Transaxle is that it operates without freewheels. Shifting between individual gears takes place by means of overlapping clutch engagement and release.
The advantage of overlap shifting are as follows:
- The transaxle can be of more compact design and is lighter on account of the absence of freewheels and the lower number of shift elements.
- Lower drag losses, i.e. higher efficiency.
- Lower peak torque acting on the components and driveline.
However, overlap shifting necessitates high-performance hardware and software, and precision engine signals.
