TCI has expanded its drivetrain lineup with the 4x Four-Speed Automatic Transmission Series that allows the use of a popular 4L80E or 700R4 transmission with non-GM performance applications.

Both the 4L80E and 700R4 versions of the 4x Four-Speed feature an SFI-spec adapter bellhousing for easy installation behind a Small or Big Block Ford, Ford Mod, Small or Big Block Chrysler, Gen III Hemi, Buick, Pontiac, Olds or GM engine.

The electronic overdrive 4L80E-based version includes an adapter flexplate that uses the engine crankshaft bolt pattern and the GM torque converter pattern. Rated to 875 HP, it can be used with an original GM transmission controller or a TCI EZ-TCU.

The fully mechanical 700R4-based version features an adapter flexplate, transmission cooler, dipstick and all necessary hardware. It is designed with street rodders in mind and is available in two power levels: 550 HP and 750 HP. Application-specific kits do not require a transmission controller and use a Constant Pressure Valve Body to eliminate the need for a TV cable - the most common source of 700R4 failure. A compact design means the transmission will fit in most applications without the need for tunnel modifications.

ELECTRONIC 4L80E-BASED:
  • Adapter bellhousing allows installation of 4L80E transmission behind non-GM engines
  • Flexplate has specific engine crankshaft bolt pattern and GM torque converter pattern for an easy installation
  • Use with original GM transmission controller or a TCI EZ-TCU, for custom programming or stand-alone use
  • Rated to 875 HP
