New kit eliminates converter shudder while reducing wear and heat

OE transmissions are a compromise at best, delivering only adequate performance for the masses. Performance enthusiasts can effectively upgrade their Ford E4OD/4R100 transmissions with the installation of TCI®’s new Valve Body Improver Kit. Complete with everything you need, along with detailed instructions, the TCI® Valve Body Improver Kit reduces internal transmission slippage and solves internal lubrication problems. With more positive converter clutch engagement, converter shudder is removed, increasing durability.

The TCI® Valve Body Improver Kit for E4OD/4R100 Ford transmissions incorporates a metal replacement converter drain back. This component replaces the problematic OE valve, which can cut off lubrication to the overdrive planetaries if it fails. In addition to correcting a number of common internal high performance problems, the new TCI® E4OD/4R100 Valve Body Improver Kit greatly improves shift quality and overall transmission life.
