TCI 4L60E/4L65E bolt-together torque converters feature a triple-disc lock-up configuration and a bolt-together design that allows for easy disassembly. Removing the billet front provides access to the entire lock-up assembly, turbine, stator, and bearings for servicing or restalling for future vehicle modifications. To further enhance strength, TCI has included both a precision-ground billet impeller hub and billet front that is CNC-machined to reduce ballooning, while the billet turbine hub, billet lockup piston and billet clutch hub are pre-hardened. These patent-pending converters use a triple-disc lock-up clutch that utilizes woven carbon frictions designed to withstand the punishment of continuous slip lock-up control. The effective diameter of the clutch in conjunction with the triple-disc configuration provides for significantly higher torque capacity over the stock clutch. The lock-up clutch is attached to an industry-exclusive self regulating clutch hub which hydraulically modulates the apply pressure to allow for the smoothest engagement of any 4L60E/4L65E converter on the market. Additional benefits include: * Bolt-in modification with no tuning required * Billet, bolt-together, self-servicable, enabling you to easily change your stall speed right at home * Fully furnace-brazed, computer balanced, and hand assembled to precise tolerances * Premium roller bearings and HDT (Heat Dissipating Technology) coating which enables lower operating temps and more efficient operation

TCI StreetFighter transmissions are durable enough to withstand the rigors of even the toughest street machines. Equipped with a manual/automatic valve body, 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 race track shift that bangs through the gears and shaves time off of your ETs. When you use the manual gear selection feature, the StreetFighters upshift and downshift right when you move the lever, with no lag or governor override. When you select the normal drive position, they retain positive automatic shifts for the ease of driving you look for in an automatic transmission.

Operating line pressure is the lifeblood of any automatic transmission by providing the clamping force on the clutches and bands. Oftentimes, increasing line pressure is a requirement when increasing driveline output. TCI's new 4L60E boost valve assemblies provide you the means of elevating your line pressure while also addressing wear issues that may actually have your transmission running at a lower level of pressure than GM intended! Features include: * Larger valve diameter over stock which yields 10-15% higher line pressure * O-rings on boost sleeve which prevent loss of boost signal pressure * Sleeve constructed from Alcoa Deltalloy 4032 & valve is hard-coat anodized which prevents wear between the mating parts
