The F5M51 is a 5 speed manual transaxle used in the TE through TW Magna and the DB 380 with V6 engines and front-wheel drive.

The F5M51 is a much simpler design to the transaxles used in earlier Magnas. It uses a two-shaft design (whereas the older transaxles used three) and doesn't need to reverse the torque before output. On earlier Magna/Veradas the torque had to be reversed because the engine rotated in the opposite direction to the wheels.

Instead of using a conventional flywheel the F5M51 uses a three piece flywheel and flexible plate assembly to reduce drivetrain vibration.
