The Hyundai A4BF2 4-speed automatic transmission was assembled in Korea from 1996 to 2010 and installed in two generations of the Elantra, as well as the platform-sharing Matrix and Coupe. This transmission was developed jointly with Mitsubishi and shares many similarities with the F4A22 automatic transmission.

Using

Disadvantages of the Hyundai-Kia A4BF2 gearbox
- Early production automatic transmissions suffered from poor build quality and a number of components;
- All other problems with this automatic transmission are related, one way or another, to rapid bushing wear;
- This causes reduced lubrication pressure and the clutch packs to burn;
- Then, dirt from the burnt clutches clogs the valve body, and the transmission begins to struggle;
- Differential bearings and solenoid wiring are also considered weak points.
