The F5A51 is an electronic 5 speed automatic transaxle by Mitsubishi used in the J through W series Magna/Verada.

All versions used in Australia have had "tiptronic" or sports mode functionality. The F5A51 is very similar to the F4A51 4 speed automatic. It uses a two-shaft design and features INVECS II technology.

Initially the F5A51 was only available on the TJ Sports and VR-X. The F5A51 later became optional on the TJII Magna Advance and standard on the KJII Verada.

The F5A51 became the standard automatic transmission across the range for the front-wheel drive L and W Series Magna/Verada.
