Factory Tech Transmission Performance

This Factory Tech E9 unit is for 1990-1993 FORD E4OD Gas Engine applications.

Factory Tech Accumulator Valve Body

• Better performance
• Improved quick firm shifts
• Transmission runs cooler
• Extends the longevity of your transmission
• Increased fluid pressure
• Less clutch slippage
• Less clutch wear
• Prevents common transmission failures


The FTVB is a complete accumulator re-calibrated for shorter shift duration, which decreases heat generated and reduces slippage and wear on the friction plates. The FTVB is tuned for the chip to leave all transmission settings at stock, if the chip does this it works great, or you can have your tuner return all shift timing and line pressure settings to factory stock, it will work with the elevated line pressure, but using software to control shift duration is bad for the pump and I don't recommend it.
