It is their first completely computer controlled transmission and their first to have a transmission with a converter clutch.

This electronically controlled 5 speed automatic transmission consists of 3 compound planetaiy gear sets, 3 multiple disc driving clutches, 3 multiple disc brake clutches and 2 free-wheel clutches, with 5th gear being overdrive.

The Electronic Transmission Controller (ETC) controls transmission operation matching engine performance during the shift phase. The driver can choose between 2 driving programs, “S” for standard driving programs and “W” for winter driving programs. Winter option provides a second gear start and a higher gear ratio for a reverse movement. Standard mode provides a first gear take off and a lower reverse gearratio.
