Instead of replacing your automatic transmission’s whole valve body, you can get better performance out of your stock valve body with a transmission shift kit. Different manufacturers use different components and techniques, but they all modify the way transmission fluid is routed through the valve body. Some kits are made for racing and performance driving, while others are for towing and heavy-duty hauling. Whatever your application demands, Summit Racing Equipment has the shift kit you need.
