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 Four-Speed transmissions are automatic overdrive 4-speeds with lock-up, so simply choose the one that fits your power level.
