What Does the Priority Valve Do?
Simply worded, the priority valve in the 10L90-E and it’s corresponding family of transmissions is the valve system used to control lubrication flow between the torque converter and the shafts/gearsets in case of a low fluid level or low fluid pressure condition. It’s responsible for prioritizing which receives lubrication flow and how much, hence the name “priority valve.”
Why Upgrade the 10L90-E Priority Valve?
As you could have guessed, this is a common leak point inside the valve body. When this leak takes place, it can lead to direct failure of the bushings, bearings, torque converter, internal drums and indirect failure of many other things as it’s likely to cause high operating temperature.
Given these facts, an upgraded priority valve is absolutely imperative in any 10L90-E transmission build. By using the Project Carbon 10L90-E Priority Valve Upgrade, you’ll be addressing all possible failures of this valve in two main ways.
Firstly, the valve is manufactured from extremely high grade billet aluminum alloy and further anodized for protection from future wear to both the bore and the valve itself. This ensures that the valve performs very well both upon initial install but also as the miles add on.
Secondarily, the Project Carbon 10L90-E Priority Valve Upgrade features an ultra-high temperature rated O-Ring to seal off the back of the valve where this leak takes place. The land that separates the oil flow portion of the valve from the spring pedestal experiences side load that can cause bore wear of up to 0.003” in extreme cases. Our O-Ringed valve can seal up to 0.010” of bore wear reliably, allowing this valve to be used with no machining.
Further, due to its modified design, this valve can be installed in an old and worn valve body to replenish proper operation of the priority valve system. Prevent torque converter and geartrain failure with this easy to install valve upgrade.
Why Choose Project Carbon Valve Body Upgrades for My Vehicle?
Designed to be simply the best of what can exist, Project Carbon valve body upgrade products are 100% engineered and manufactured here in the USA by Next Gen Drivetrain. Committed to supporting American-made, all Project Carbon valve body upgrades are brought to life by caring and talented machinists with years of experience.
When these valves body products are designed, our first priority is to design the perfect version of whatever it is. What is the most durable material we can use? What will perform the best? What will be the most reliable over the years that someone owns or uses this vehicle? All of these questions are scrutinized for long periods of time during the design of each and every component.
Furthermore, we make zero attempt to cut cost in subduction of quality. Priority #1 is the quality, reliability and performance of the upgrade, with cost-savings being a distant second. There are plenty of companies sourcing poorly designed parts with unoriginal designs from other countries and selling them for lower prices, and we have no interest in doing the same. When you choose Project Carbon valve body parts, you can trust that you chose the best.
Lastly, we offer the most aggressive quality control measures available on all valve body parts. We design custom fixtures for each valve to be tested in that are identical to the factory valve body or case, allowing us to vacuum test every valve or plate by hand before they leave. This means that you have the added layer of confidence that you’re using nothing but the best in your transmission.
