John Wood 4R100 Valve Body 7.3L Powerstroke 1996-2003

We offer modified accumulator valve bodies from John Wood Automotive because it is our experience that they are one of the best offered in the industry.  John Wood has been building transmissions and valve bodies since 1983 and has a reputation for strong attention to detail, quality before quantity and excellent customer service. 

A JW Valve Body will help to firm up shifting, while keeping the shifts crisp and not banging into gear.  Also performs shorter shift duration, which decreases heat generated and reduces slippage and wear on the friction plates. While the valve body can be used with stock programming, we suggest a PHP Hydra if you are thinking of upgrading.  

Please note that there is a 4 week window for core returns from when you receive the shipment.  If the core isn't received back 30 days from customer receipt then your core charge will be forfeited.

Core Shipping Options:

• Pre-Ship Core - This allows you to ship your used cores in first without have to pay a core charge. Your order will ship once your cores are received.
• Return After Install - This is the quickest option to get your valve body. You pay the core fee up front and then it is refunded once the core is returned.
