These transmission pans provide an additional 2 quarts of fluid capacity. Each pan is constructed of thick durable cast aluminum with CNC machined mounting surface, bolt holes and ports. In addition to the extra oil capacity they feature deep aluminum fins that increase the pans cooling ability. They have a drain plug for easy fluid changes and include gasket and bolts. No modifications to the dipstick are needed. Note: Filter extensions are included for applications that require the filter to be moved closer to the bottom of the pan. **Includes instructions**
