TCI 4x FOUR-SPEED Automatic Transmission Package (SMALL BLOCK FORD & GM 4L80E)

The popular 4x Four-Speed line of automatic transmissions is now compatible with Small Block Ford engines using either a 28 oz. or 50 oz. external balance. You now have the capability of running a 550 HP or 750 HP capable 700R4-based transmission behind your externally balanced SBF without the use of difficult adapter plates. If you need a transmission that can hold more than 750 horsepower, TCI also offers an 875 HP capable 4L80E-based automatic transmission for these engines.

TCI makes it easy to adapt these proven transmissions to compatible engines by including the exact bellhousing, a special adapter flexplate, pilot adapter, dipstick and other accessories in a complete package. These kits bolt right up to your engine like a stocktransmission.

The 700R4-based transmission uses a Constant Pressure Valve Body to eliminate the need for careful TV cable tuning, the most common cause of 700R4 transmission failure. If you choose the 4L80E-based 4x transmission, these controls are handled electronically by your choice of the TCI EZ-TCU, TCU 2.0 or a factory GM transmission controller. All 4x transmissions are automatic overdrive four speeds with lock-up, so simply choose the one that fits your power level.
