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 during the installation of the valve body. We can supply you with a quality filter if you don't want to supply your own. Just select the option to "Add 4R100 / E40D Filter" when you are adding the valve body to your cart.

We have also included an option for us to supply you with a pre-paid (at a discounted rate) UPS return label for your valve body core. This will allow you to simply seal your clean valve body core and core return form back up in the same box we sent you, cover the old label with the new one and give it to any UPS driver or drop-off without having to hassle with shipping details.

A $150 refundable core charge will be automatically added to the purchase of this product.

Cores MUST be returned within 30 days of product delivery (as verified by UPS tracking information) to receive the full core refund. Cores received after 30 days will receive a pro-rated refund. Please remember that the valve body you are ordering was once a core that someone else was kind enough to considerate of the next customer and return your core as quickly as you can! We NEED your core as much as you NEED your money back!
