The Project Carbon® 6L90-E Valve Body

    Welcome to the Project Carbon® 6L90-E High Performance Valve Body by Next Gen Drivetrain™. This valve body is designed to be the perfect dichotomy between practicality and performance; maximizing both without sacrificing the other. We’ve done an incredible amount of research on the 6L90-E valve body over the years, and have compiled much of that information into our coveted Project Carbon® valve body series.

     The 6L90-E transmission is electronically controlled, and hence the valve body's primary function is to ensure that all oil reaches the designated locations in the most efficient and expedient fashion possible. This has been the primary design feature of our 6L90-E valve bodies from day one.

A Valve Body for Everyone

     At Next Gen Drivetrain™, we are well aware that not all customers are seeking the same desired end state. Some customers seek the ability to tow triumphantly over large grades and maintain cool temperatures; maximizing longevity. On the other hand, we have customers seeking the ability to displace as much power as possible, and naturally, everything in between.

     We pride ourselves on dominating the 6L90-E valve body with superior technology that allows us to deliver a true totalitarian solution that is designed to bolt into any unmodified 6L90-E and produce incredible results without the need for complicated modifications to tuning or shift dynamics.

     In fact, this valve body is 100% bolt in, tuned or untuned in almost all cases. Naturally, not all tuners tune the same and it would always be smart practice to communicate with one of our experts first to ensure smooth sailing at all points in the transition to your vehicles new and enhanced valve body.

     Something that most should understand is that the valve body is not the part of the transmission that produces pressure, but rather the pump. The reason the valve body is critical in producing pressure is because it is easily the largest leak-point in this transmission. Our flagship valve body, the Project Carbon®, absolves these concerns in totality, justifying our unique Lifetime Warranty on this product.

     To access increases above factory line pressure, you must employ some form of TCM tuning to instruct the transmission to electronically command more line pressure. Our valve body is 100% pre-configured for increased line pressure and can run safely and properly with or without TCM tuning.
