Automatic Transmission

9-Speed Automatic Transmission

Heading for a whole new dimension

The ZF 9-speed automatic transmission for passenger cars with front-transverse engines. Thanks to the modular principle, different starting elements and all-wheel drive applications can be implemented cost-effectively even given the restricted installation space conditions with front-transverse passenger cars.

Advantages

  • Planetary gearset with 9 speeds, 4 simple gearsets, and 6 shift elements. Gearsets are nested to save space
  • Wide transmission ratio spread (nearly 10) with small ratio steps
  • The first-ever use of interlocking dog clutches in a passenger car powershift transmission
  • Torque converter with excellent vibration and oscillation isolation for optimal comfort during starting (driveoff) and shifting
  • Proven ZF control systems technology helps provide the excellent shift quality known from the 8HP

Product Details

More driving comfort and dynamics – lower fuel consumption

The new, innovative 9HP automatic transmission for vehicles with front-transverse mounted engines updates the classic advantages of all ZF automatic transmissions for the future: excellent efficiency and dynamics with low fuel consumption, agility combined with driving comfort, and superior driving pleasure – all created by passionate engineering.

The core of the innovative concept is its modular construction system. This design makes the most of the available space and creates the best possible conditions for versatile front transverse applications. These and other advantages make the 9HP automatic transmission extremely flexible and an optimal choice for front-wheeldrive and all-wheel-drive cars worldwide.
