TCI Automotive Non-Electronic 4x Four-Speed Package for 8-Bolt Ford Modular (550 HP)

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 Chevrolet Small/Big Block engine.

The electronic overdrive 4L80E-based version includes an adapter flexplate that uses th e 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.
