(fits 99-03 7.3L Powerstroke / 4R100 equipped trucks)

Our valve bodies are built by John Wood of John Wood Automotive, one of the premier 4R100 builders in the country. They are configured to offer improvements in shift quality without being harsh and without causing the "reverse delay" found in some shift kit configurations. This valve body also works GREAT with the DP-Tuner programming we offer! It should also work great with other tuning due to not being overly aggressive in the shift firmness.

Installation of this valve body will result in:

• Quicker, more Positive Shifts
• Elimination of "Shift Flare"
• Reduced Temperatures
• Reduced Clutch Slippage
• Reduced Clutch Wear

NOTE: Installation of this valve body will require the use of an IN/LB torque wrench. If you don't have access to the correct tool, we recommend having a qualified mechanic perform the installation.

We HIGHLY RECOMMEND installation of a new transmission filter with the installation of the valve body. We can supply you with a quality filter if you don't want to supply your own...see the options below.

A $150 refundable core charge will be added to the purchase of this product unless "send core first" is selected below. If "send core first" is selected, we will NOT process or ship the order until the core is received.

We have eliminated the time limitation for core return because we really need the cores back. Instead, we ask that cores be returned AS SOON AS POSSIBLE because we are currently experiencing delays in producing new JWVBs due to a lack of cores. Please be considerate of the customers that come after you and return your core as quickly as you can! We NEED your core as much as you NEED your money back!
