Consider Your Old F-car T-56 Obsolete!


Designed to replace aging T-56 transmissions in LS1-powered fourth-generation GM F-bodies.
These transmissions are the strongest 6speed manuals ever built.
They can withstand up to 700 ft.-lbs. of torque, with gears featuring substantially increased face widths

The Magnum-F is the latest addition to TREMEC’s hard-hitting Magnum 6-speed series. Based on the TR-6060 used in numerous late-model factory performance machines, it combines brute strength with modern OEM refinement for the ultimate gear-rowing experience.
Built to surpass even the most heavily fortified T-56, it also eliminates the need for over-hyped ‘Stage 6’ or ‘Level X’ rebuilds; along with the concern that comes from rebuilding with inferior offshore parts.

What’s Inside:

Inside, this new transmission benefits from the same durable components found in many of today’s hardest-hitting OEM muscle & sports cars.
Over the T-56, the Magnum-F boasts increased face-width on all gears, a robust combination of double and triple cone synchronizers, enhanced webbing in the main case, provisions for a cooler circuit, and more!
TREMEC also took the opportunity to upgrade the shifter to an isolator-type unit, like that found on its Magnum XL. 
This shifter reduces in-cabin noise and vibrations while at the same time providing the precise and communicative shift feel that all Magnums are known for.

Just like all TREMEC aftermarket transmissions, the Magnum-F is made from 100% brand-new OEM-quality content.

MEET THE MAGNUM  6-SPEED called the F:

Magnum F the long-awaited and highly-anticipated F-car-specific version of TREMEC’s popular Magnum 6-speed has finally arrived!
Designed to replace T-56 transmissions in 1998-2002 GM F-bodies, the new-F leverages TREMEC’s pervasive TR-6060/Magnum architecture in order to provide fourth-gen enthusiasts significantly improved performance and relief from a shrinking pool of quality T-56 replacement parts.


” Aimed first & foremost at ‘98-02 F-cars
The Magnum-F can also be used in third-gen and LT1-powered F-bodies with minimal modification.”

in addition to a host of sport compact applications that previously relied on the F-car T-56 for its ideal shifter location.

Available now through Modern DriveLine, the Magnum-F is the trans rendering junkyard crawls and custom builds a thing of the past!


From great beginnings:

Born in the vacuum created by the release of the original T-56 Magnum (now known simply as ‘Magnum’) back in 2009.
The Magnum-F fills a longstanding void in the overall Magnum line with regard to shifter locations; addressing not only LS1-powered ‘98-02 F-bodies.
As well as several other applications that utilize a similar shifter position.
These include third-generation F-bodies, LT1-powered fourth-gens, LS-swapped late models of all varieties, and sport compact applications such as A80 Supras, FD RX-7s, and more!


Where the original Magnum shifter locations may prove too far forward, and the extended length Magnum XL’s too far back.
Tremec’s Magnum-F’s in-between position often proves to be just right.

  • MD-586-16363 (TUET16363) with  2.97 first Gear

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.
