TCI Streetfighter Transmissions

The TCI Streetfighter transmission is tough enough to withstand the rigors of even the toughest street machines. It is ideal for vehicles powered by engines producing up to 450 horsepower. with a non-supercharged system using pump gasoline.

Equipped with TCI's Manual/Automatic valve body, it allows 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 ET's.

When you use the manual gear selection feature, the Streetfighter upshifts and downshifts right when you move the lever, with no lag or governor override. When you select the normal drive position, the transmission retains positive shift for the ease of driving you look for in an automatic transmission. 

TCI also goes the extra mile to ensure your transmission is superior in both form and function. Beginning with a careful inspection of the transmission case and components that will be used, we replace stock parts with high performance clutches, bands and components where applicable. TCI increases fluid flow, lubrication system and thrust capacity. Problematic hard parts are replaced with stronger components, many of which TCI fabricates themselves at their in-house machining centers.

Finally, each and every TCI Streetfighter transmission must pass both a static pressure test during assembly and a final dyno test prior to shipping. So you can be confident you're getting a transmission that's ready to rock.
