TCI 6x Six-Speed Transmission Packages

Ashland, MS – The next generation of the 6x Six-Speed™ Transmission from TCI® features a new overrun clutch apply. This increases the torque capacity and adds to the durability of the overdrive roller clutch. New package options offer nearly all the transmission components enthusiasts need from just one manufacturer.

The original TCI® 6x Six-Speed™ Transmission provided six forward gears and fully programmable automatic or manual shifting for improved acceleration and fuel economy at cruising speeds. Now the engineers at TCI® have improved on that model and redesigned the patented 6x valve body, resulting in a transmission that boasts higher torque capacity than ever before. This new design provides overrun clutch apply in first, third and fifth gear.

The shifting strategy has also been improved and refined, meaning that each second-generation transmission shifts even smoother than the original 6x. TCI® 6x Six-Speed™ Transmissions are capable of handling up to 850 horsepower and are available for all popular GM, Ford and Chrysler applications. Packages feature the 6x Six-Speed™ Transmission, a bellhousing (dependent upon application), optional Outlaw™ or paddle shifter, TCI® EZ-TCU™ Transmission Controller, wiring harness, transmission cooler, dipstick and Max Shift™ Street Performance Transmission Fluid. These proven packages come with a limited lifetime warranty.
