Overview

The fully mechanical 4x Four-Speed Auto Transmission (non-electronic 700R4-based) includes an adapter flexplate, transmission cooler, dipstick, and all necessary hardware. TCI's 4x Four-Speed Automatic Transmission Series allows the use of popular 4L80E or 700R4 transmissions with non-GM performance applications. Both 4L80E and 700R4 versions feature an SFI-spec adapter bellhousing for installation behind Small or Big Block Ford, Ford Mod, Small or Big Block Chrysler, Gen III Hemi, Buick, Pontiac, Olds, or Chevrolet Small/Big Block engines. The electronic overdrive 4L80E-based version, rated to 875 HP, includes an adapter flexplate for engine crankshaft bolt patterns and GM torque converters, compatible with original GM transmission controllers or a TCI EZ-TCU. The mechanical 700R4-based version, designed for street rodders, is available in 550 HP and 750 HP levels. Application-specific kits do not require a transmission controller and use a Constant Pressure Valve Body to eliminate the need for a TV cable, a common source of 700R4 failure. A compact design allows fitment in most applications without tunnel modifications.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
