WHAT IS A ZF TRANSMISSION?

We at North Bay Bavarian are experts in all models of transmissions used in BMW vehicles. Many wonder how their ZF transmission differs from standard transmissions.

A ZF 8HP transmission is an 8-speed longitudinal automatic transmission manufactured and designed by ZF Friedrichshafen. The transmission first hit the market in the BMW 7 Series 760Li with V12 engine. Various other models have been fitted with the ZF transmission through the 1 Series.

One major benefit to the 8HP ZF transmission is its enhanced fuel economy. Studies report that the 8HP ZF transmission can be nearly 15% more efficient than standard transmissions.

Shift times are lightning fast with the 8HP ZF transmission with some reports identifying shift times at 200 milliseconds. Non-sequential shifting is a welcome feature for emergency situations.

Common ZF Transmission Issues

  • Trans. malfunction messages
  • Shifting lacks ease (shifts hard)
  • Error Message: transmission fail safe drive moderate
  • Transmission caught in gear
  • Incorrect Gear Ratio
  • Transmission will not shift as engine revs
  • Irregular shifting when during gear change
  • Lag between gear shifts
  • Slipping of transmission
