Performance Valve Body

The JLP Valve Body is engineered to enhance the performance of your 4R100 automatic transmission. This unit is professionally built using all new components, including heavy-duty valves and springs, to ensure durability and optimal function. The primary benefit of this valve body is its optimized shift characteristic: it minimizes harshness during light throttle application, yet provides a more decisive and firm shift when you apply more throttle. This results in a more engaging driving experience without the jarring impact often associated with performance transmission modifications, preventing "spilled drinks." The performance of this valve body is proven, as it is the same unit utilized in the brand's own 9-second "Lightning" race vehicle. While the product page does not explicitly list vehicle fitment, the "4R100" designation in the product title and surrounding evidence strongly suggests compatibility with vehicles equipped with this transmission, commonly found in Ford F-150 Lightning, Harley-Davidson F-150, and certain Super Duty models, particularly from the late 1990s through mid-2000s. Evidence suggests its use in performance applications like "Lightning" trucks. It's important to note that a core charge is currently applied to this product. Customers will receive a $50.00 credit upon returning their original valve body. Additionally, related products like "JLP Transmission Valve Body & 4X4 Deep Sump Pan & Filter" and "JLP CUSTOM TUNE" are available, suggesting that a custom tune may further optimize the performance of this valve body.
