TCI Super StreetFighter transmissions bridge the gap between the StreetFighters and full Competition series transmissions. Like the StreetFighter units, these are equipped with 100 percent tested, manual/automatic valve bodies. That means that most units allow you to manually shift the vehicle into each gear change or, by placing it in the drive position, remain fully automatic. In either mode, you get a racetrack shift that bangs through the gears and shaves time off your ETs. When you use the manual gear selection feature, the Super StreetFighters upshift and downshift right when you move the lever, with no lag or governor override. When you select the normal drive position, the transmissions retain positive automatic shifts, for the ease of driving you look for in an automatic transmission.

The kingpin of Tremec's high performance lineup, the T-56 Magnum double-overdrive 6-speed manual transmission, takes the very best from Tremec's current OEM technologies and pairs it with the most popular features of the TKO 5-speed. Known in its original equipment form as the 'TR-6060', the Magnum is an aftermarket version of the same transmission found in many of today's most celebrated factory super cars. Able to withstand a massive 700 lbs.-ft. of torque while providing unbelievably crisp shifts, no other manual transmission on the planet offers as much combined strength, versatility, and general ease-of-use as the T-56 Magnum. The units are available in a variety of gear ratios for different applications. Additional details: * The aftermarket's premier double overdrive 6-speed performance manual transmission * Reasonably light at 135 lbs. dry * Multiple shifter locations and dual speedo pickups for unmatched versatility * Incredibly short, extremely low-effort shift throws, with crisp, precise engagement * Modern OE supercar technology for the ultimate pro-tourers, road-racers, and more

Tremec introduces the Magnum-F 6-speed manual transmissions for fourth-generation Camaros and Firebirds. Designed to replace T-56 transmissions in 1998-2002 GM F-body cars, the Magnum-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. 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, but several other applications that utilize a similar shifter position. Beneficiaries 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, the Magnum-F's in-between position often proves to be just right. Inside, the Magnum-F benefits from the same durable componentry found in many of today's hardest hitting OEM muscle and sports cars. Over the T-56, the Magnum-F transmissions boast 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. The 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. And, like all Tremec aftermarket transmissions, the Magnum-F is made from 100 percent brand-new OEM-quality content. Models with different gear ratios are available. Additional notes: * Close Ratio version for high performance street and road racing * 700 lbs.-ft. of torque capacity * Reasonably light at 135 lbs. dry * Multiple shifter locations and dual speedo pickups for unmatched versatility * Choice of two different gear ratio sets with unique double overdrive ratios * Incredibly short, extremely low-effort shift throws, with crisp, precise engagement * Modern OE supercar technology for the ultimate pro-tourers, road-racers, and more

Sonnax Smart-Tech drum modules for racing GM TH400 transmissions improve on-track performance and consistency, leading to quicker ETs, more wins, and greater reliability. The TH400 is preferred for its overall durability and multitude of available ratios, but is known to be heavier and less efficient than the popular two-speed Powerglide. Part of the TH400 inefficiency results from the fact that the direct drum counter-rotates, spinning backwards in 1st gear, brakes to a complete stop on the 1-2 shift, then goes from 0 RPM to input RPM on the 2-3 shift. Significant energy is wasted through this cycle that robs power, upsets traction on the shifts, and contributes to broken internal parts. Compared to aluminum direct drums, the Smart-Tech drum module reduces the weight of the counter-rotating components by over 3.3 lbs.! And more significantly, because the weight of the Sonnax counter-rotating parts is closer to the centerline, there's a 68 percent reduction in energy required to stop and restart during the 1-2 and 2-3 shifts. The benefits are increased wheel horsepower, better acceleration, less shock on the shifts, and improved durability. * Complete kit (34555-01K) replaces both forward and direct drums and includes everything from intermediate sprag to the pump; a selection of Sonnax input shafts is available separately. * 100 percent new content, no used core pieces * Includes larger-diameter, 36-element sprag and sprag race that works with OE intermediate clutches * Includes six-friction forward clutch pack and seven-friction direct clutch pack Contents: * Forward Piston Housing * Forward Piston * Forward Piston Return Springs (16) * Forward Spring Retainer * Forward Snap Ring * O-Ring 1.674 in. * Lip Seals (2) * Direct Housing Assembly * Direct Piston * Direct Piston Return Springs (26) * Direct Spring Retainer * Direct Snap Ring * O-Ring 2.737 in. * Sprag Shaft * Front Sprag Retainer Plate * Heavy-Duty Sprag 36 Element * Outer Sprag Race * Rear Sprag Retainer Plate * Sprag Retainer Screws (4) 6-32 x 5/16 in. * Quad Ring Seals (2) * Anti-rotation Seal Rings (2) * Drum * Pressure Plate * Outer Snap Rings (4) * Bearing Small * Forward Clutch Hub * Bearing Large * Direct Clutch Hub * Steel Clutch Plates (4) .060 in. * Steel Clutch Plates (11) .077 in. * Friction Clutch Plates (13) .080 in. * Clutch Separators (60) .103 in.
