The TCI 242950 is a 4L80E/6X high-stall triple-disc bolt-together torque converter with a 3000 to 3200 RPM stall range. It features woven-carbon friction, lock-up control technology, a removable billet front, pre-hardened steel construction, and internal access for the lock-up assembly, turbine, stator, and bearings.

The bolt-together design supports servicing or re-stalling if future vehicle modifications change converter requirements. The billet front is CNC-machined from pre-hardened steel, while the pre-hardened billet turbine hub, lock-up piston, and 50-spline clutch hub add strength in key converter areas.

The converter is fully furnace-brazed, computer-balanced, and hand-assembled to precise tolerances. Its triple-disc lock-up layout and serviceable billet-front construction make it a serious option for builds that need a high-stall 4L80E/6X converter with room for future changes.

The TCI Super StreetFighter 411205 is a C6 automatic transmission assembly for Ford big-block applications including 351M, 400, 429, and 460 engines. It uses a 13-1/2 in tailshaft, 2.46 gear ratio, and a configuration without torque converter or lock-up, with extreme performance clutches, nitride steel plates, extra-wide power bands, larger diameter servos, and a chrome plated TCI pan.

This transmission is intended for normally aspirated vehicles producing up to 875 hp, depending on application. Higher line pressure, increased thrust capacity, stronger band apply, and improved lubrication work together to deliver firmer shifts, greater torque capacity, and reduced slippage under demanding street and strip use.

The larger servos, extra-wide bands, nitride plates, and chrome TCI pan preserve the core Super StreetFighter hardware advantages. It is supplied without a torque converter, giving the builder control over converter selection. Oversized freight restrictions and additional charges may apply.

The TCI Saturday Night Special 450900 is a torque converter for 1970 to 1979 Ford C4 applications with a 26 spline setup. It brings several construction details from TCI competition models into a street-focused converter, including furnace-brazed fins and a hardened pre-ground pump hub.

This converter is positioned for show cars, street rods, and performance street builds that need a cost-conscious step up from a basic converter. The Saturday Night Special line is built to add premium performance character while keeping the application street friendly.

Furnace-brazed fins and the hardened hub are the key durability details available for this SKU. Verify the C4 transmission, 26 spline requirement, and 1970 to 1979 application before installation.

The TCI StreetFighter 371000P1 is a 700R4 automatic transmission package for 1984 to 1993 Chevrolet V8 applications. The package combines a triple-tested TCI transmission, precision-tuned TCI torque converter 242800, universal transmission cooler, three gallons of TCI Max Shift Street Performance fluid, and included hardware.

This package is built for non-supercharged street machines using pump gasoline, with application-dependent support from 400 to 775 hp. Special clutches and bands, roller clutches, improved lubrication, and higher line pressure work together to increase holding capacity, deliver firmer shifts, and reduce slippage.

The 700R4 configuration includes lock-up, a 30 spline input, and a 3.06 gear ratio. Manual or automatic shift operation supports both street use and more aggressive strip driving, while the included cooler and fluid help make the package more complete for the build.

The TCI StreetFighter 311010 is a TH350 automatic transmission assembly for Chevrolet 4.3 and V8 engine applications. It uses a 6 in tailshaft, forward shift pattern, 2.75 low gear set, new sprags and roller clutches to increase holding capacity, a standard capacity pan, and a configuration without torque converter or transbrake.

StreetFighter transmissions are built for non-supercharged street machines using pump gasoline, with application-dependent support from 400 to 675 hp. Higher line pressure, improved lubrication, and stronger holding components help deliver firmer shifts, greater torque capacity, and reduced slippage for street and strip use.

The chrome plated TCI pan adds a finished appearance, while the improved lubrication system increases fluid delivery to planetaries and internals. The 2.75 low gear set and upgraded sprags and roller clutches are important differentiators for this TH350 assembly. Oversized freight restrictions and additional charges may apply.

The TCI 278000 is a cast aluminum deep transmission pan for GM 4L80E and 4L85E applications. It adds 2 qt over OEM capacity and uses a natural silver cast aluminum body with cooling fins, a drain plug, filter, filter extension, gasket, and bolts.

Added fluid capacity and cooling fins help manage transmission heat, while the cast aluminum construction adds strength and rigidity to the transmission case. The pan is built to work with the stock dipstick, so the upgrade does not require dipstick modification.

The included magnetic drain plug improves service access, and the supplied pickup extension, pan gasket, and stainless steel installation hardware support a complete installation. This pan is Made in USA and carries limited racing and street or strip warranty coverage.

The TCI Maximizer Street 241602 is a non-lock-up torque converter for GM TH400, TH425, and TH375 transmissions. It is built for towing and truck use with a 1600 to 2000 RPM stall range, wide bolt pattern, balanced construction, anti-ballooning plate, extra reinforcement, tougher turbine splines, and thicker mounting surfaces.

This converter is made for modified off-road 4x4 trucks and daily-driven trucks that need better initial takeoff without lugging the engine on big tires. The added stall range helps match the converter to the truck’s power range, while the reinforced construction is intended to handle additional drivetrain load and vibration.

TCI notes improved rear wheel horsepower and elapsed times as a result of this converter design. The wide bolt pattern and anti-ballooning plate are key fitment and strength details to verify before purchase. Warranty coverage is limited to 30 days for racing use and 90 days for street or strip use.

The TCI StreetFighter 211000 is a TH400 automatic transmission assembly for Chevrolet engine applications using a 4 in tailshaft. It is configured as a non-variable pitch TH400 unit without a torque converter or lock-up, with an improved lubrication system and a chrome plated transmission pan carrying the embossed TCI logo.

StreetFighter transmissions are built for non-supercharged street machines using pump gasoline, with application-dependent support from 400 to 675 hp. Higher line pressure helps produce extra firm shifts, greater torque capacity, and reduced slippage, while manual or automatic shift operation gives the driver flexibility for street cruising or quicker strip shifts.

The 2.48 gear ratio and 30 spline input shaft are useful fitment details for matching the rest of the drivetrain. The improved lubrication system increases fluid delivery to the planetaries and internals, and the included chrome pan gives the assembly a finished TCI look. Oversized freight restrictions and additional charges may apply.

The TCI Super StreetFighter 211005 is a TH400 automatic transmission assembly for Chevrolet engine applications using a 4 in tailshaft. It is built as a bridge between the StreetFighter line and full competition transmissions, with extreme performance clutches, nitride steel plates, extra-wide power bands, larger diameter servos, and a chrome plated transmission pan with an embossed TCI logo.

This transmission is intended for normally aspirated vehicles producing up to 875 hp, depending on application. Higher line pressure, increased thrust capacity, improved lubrication, and stronger band apply are used to deliver firmer shifts, greater torque capacity, and reduced slippage under harder street and strip use.

The unit is supplied without a torque converter and without lock-up, so converter selection can be matched to the build. The improved lubrication system sends more fluid to the planetaries and internals, while the included chrome pan adds a clean finished look. Oversized freight restrictions and additional charges may apply.
