The reliability of Ford Focus automatic transmissions varies depending on the specific model and year of manufacture. Here’s an overview of the different types of automatic transmissions used in the Ford Focus:
4-speed automatic transmission (4F27E):
* Used in first generation Focus models (1998-2004)
* Reliability: Poor, prone to problems with slippage, overheating and failure.
5-speed automatic transmission (5F50N):
* Used in second generation Focus models (2005-2011)
* Reliability: Much improved over 4F27E, but some oil leakage and slippage may still occur.
6-speed automatic transmission (PowerShift):
* Used in third and fourth generation Focus models (2012-2018)
* Reliability: Mixed, some models had serious reliability issues including slipping, kicking and transmission failure.
8-speed automatic transmission (8F21):
* Used in fourth generation Focus models (from 2019)
* Reliability: The transmission is relatively new and there is little data yet on its long-term reliability.
In general, the reliability of Ford Focus automatic transmissions depends on the specific model, year of manufacture and operating conditions. Some models had more severe reliability issues, while others were more reliable.
It’s worth noting that proper maintenance and regular transmission fluid changes can significantly extend the life of any automatic transmission.
