FTI Performance Torque Converters and Transmissions

Shop FTI Performance torque converters, racing transmissions, transmission internals, coolers, pans, bellhousings, and fluid at Black Ops Auto Works. Compare Street Brawler, Extreme Street Brawler, and Street Racer lock-up converter options alongside application-specific drivetrain components. Match the complete engine, transmission, converter, and driveline combination before ordering.

FTI Street and Racing Torque Converters

The collection includes selected converters for 4L60E/4L65E, 4L80E/4L85E, NAG1/722.6, AODE/4R70, 8L90E, and 10R80 applications. These transmission families use different pilot dimensions, input splines, bolt circles, lock-up arrangements, and installation requirements.

Choose the exact converter specification around the engine's torque delivery, camshaft, vehicle weight, gearing, tire size, and intended driving. Stall behavior depends on the complete combination. A nominal stall number should not be treated as a guaranteed operating speed in every vehicle.

Lock-Up and Multi-Disc Configurations

Selected FTI Street Racer listings offer billet lock-up and multi-disc arrangements, while other converter families serve different street or racing applications. Confirm the lock-up strategy, clutch configuration, transmission generation, and control requirements of the exact unit.

Check crank pilot diameter, flexplate bolt pattern, input spline, spacing, and supplied hardware before installation. A converter listed for a transmission family may still require a specific engine or vehicle configuration.

Racing Transmissions and Internal Components

This collection includes TH400 racing transmission listings, bellhousing options, direct-drum components, and converter charge-pressure control hardware. Build level, shift pattern, transbrake configuration, case, and bellhousing must be selected together. A horsepower rating for one build does not apply to every transmission or converter.

Plan mounts, crossmember, linkage, driveshaft connection, controls, cooling, fluid, and speedometer requirements for a swap. Review the complete package contents and any core or build requirements on the chosen listing.

Coolers, Pans, and Transmission Fluid

Compare stacked-plate coolers, deep aluminum pan kits, hardware, and FTI transmission oil. Match the pan to the exact transmission and available ground clearance. A deeper pan may require a specified filter or pickup arrangement and a different service-fill quantity.

Have the installer verify fluid specification, line routing, cooler capacity, converter seating, and the required commissioning checks. Use the instructions for the actual transmission build rather than a general fill or torque assumption.

Choose Your Part

• Confirm the transmission family, generation, engine, and complete FTI part number.
• Match crank pilot, input spline, flexplate bolt circle, spacing, and lock-up requirements.
• Discuss stall selection using engine torque, camshaft, gearing, weight, tires, and intended use.
• Review shift pattern, transbrake, bellhousing, controls, cooling, and fluid requirements.
• Confirm supplied hardware, package contents, and any core-return terms.

Frequently Asked Questions

How do I choose FTI converter stall speed?

Provide the complete engine and vehicle combination to an FTI converter specialist. Torque output, camshaft, weight, gearing, tires, transmission, and driving conditions affect the appropriate choice and actual stall behavior.

Will a converter fit every vehicle with the named transmission?

No. Check the transmission generation, crank pilot, flexplate bolt circle, input spline, lock-up controls, spacing, and exact application notes.

Does a racing transmission listing include a converter?

Contents vary. Some packages include matched components, while a transmission or converter listing may supply only that assembly. Review the parts list for the exact package.

Can I use the same fluid and cooler after an upgrade?

Confirm both against the new transmission and converter requirements. Fluid specification, heat load, contamination, plumbing, and cooler condition must be assessed by the installer.

Are all FTI converters rated for the same power?

No. Construction, clutch arrangement, application, and ratings vary by series and part number. Select the unit for the complete combination rather than applying one product's rating to another.
