FORD T56 Magnum 6-Speed Transmission 2.97 first .80/.63 OD/ TUET16884
Double Overdrive

Introduced in the spring of 2009, the TREMEC T-56 Magnum 6-speed manual transmission, was the long-awaited and highly anticipated replacement for the original T-56.
Magnum transmissions are the strongest 6-speed manuals ever built. They can withstand up to 700 ft.-lbs. of torque, with gears featuring substantially increased face widths.

Based heavily on the TR-6060, the all-new Magnum took the best of TREMEC’s current OEM design and manufacturing technologies and combined them with the most popular features of their intensely popular TKO 5-speed.
The result is the smoothest shifting, greatest driving, strongest, and most versatile 6-speed aftermarket transmission TREMEC has ever produced.

Driving Techniques
A 500-mile break-in period will prevent premature wear and possible damage to the transmission. During the
break-in period, you must avoid high RPM shifts and “drag” starts. The clutch must be fully disengaged to shift
the transmission. Do not use excessive force when shifting the transmission. If you experience clash shifts
(grinding), check clutch travel to ensure proper air gap is achieved. Another possible cause of clash shifting is
improper transmission installation (excessive driveline angle / resulting in poor driveline alignment). Do not hold
the transmission in gear by applying force on the shifter. This will damage the pads on the shift forks and may
result in significant damage to the transmission.
