545RFE “Bulletproof545" DIY Valve Body Upgrade Kit - V4.0

Next Gen Drivetrain, Inc.

Introduction:

     It’s no secret that the 545RFE’s Valve Body is a tragically low quality piece of equipment and is the foundation of nearly all of the unit’s failures. Our 100% proprietary Bulletproof545 kit is engineered, developed and manufactured in-house to be the all-in-one solution; addressing all probable failure points.

     This is the perfect valve body kit for ANY 545RFE build. Before learning more about this product, you might enjoy our Transmissions 101 series, where we offer free educational resources on these transmissions and their inner workings!

Solenoid Switch Valve:

     The Solenoid Switch Valve is a little known yet massive failure point in the 545RFE valve body. It tends to seize in place and cause the truck to have trouble in it's overdriven gears amongst other things. Unfortunately, this is not a part any known shift kits offer an inclusive solution for.

     Other kits available on the market offer an upgraded separator plate, or paper gaskets. This is partially helpful but fails to resolve many of the main failures of the 545RFE, especially the Solenoid Switch Valve. The SSV is a massive failure point in the 545RFE and is actually where most crossleakage tends to occur, not just the separator plate.

     To resolve this, we offer a package of drop-in axially supported and precision machined end plugs that are designed not to wear the bore of the switch valve, and also not become stuck resulting in P0871 and overdrive clutch failure. This is an extreme upgrade in reliability that will save most 545RFE owners from overdrive failure completely in stock or close to stock applications. Best of all, it's 100% drop-in!

 

The “Formula One” Separator Plate:

     Think of your separator plate as the head gasket of your transmission. It’s exposed to tremendous pressure and frequently begins to leak causing catastrophic failure. Our proprietary CNC Laser-Cut Separator plate is designed both 3x thicker to maximize sealing potential and negate this concern, but also is designed to torque to a near perfect seal on its third torque.

     This is also a single piece plate, rather than multiple paper gaskets that are to be laid together, providing ease and precision during install with the thickest and best sealing separator plate on the market. CNC Lasering also enables us to maintain the most stringent tolerances while also offering a hand finish to both mating surfaces. This separator plate puts shame to all others and is a MUST for longevity OR power!

 

Billet Accumulator Girdle:

     The Stock accumulator plate is notorious for cracking, causing a loss of line pressure to clutch packs when they need it most. The Next Gen Drivetrain Billet Accumulator Girdle is CNC Machined from high quality 3/16” steel and uses unique hardened bolts designed to maximize clamping force and engage as much thread area as possible. We also include red Loctite for the installation of the plate bolts.

 

Billet Steel NeverLeak L/R Switch Valve:

     New for the V4.0 variants of the RFE series Bulletproof kits, the Billet Steel NeverLeak L/R Switch Valve is the ultimate solution for for multiple problems. One is a slow engagement into drive or reverse, others are poor holding pressure (line pressure) in these gears because of excessive bore wear to the factory L/R switch valve.

     Our proprietary valve not only resolved this common crossleak, but features an updated chamfer design about the outside to aid in axial support to prevent seizure inside the bore; the cause of many “No Reverse” conditions. Best of all, this valve is 100% drop-in regardless of casting mileage or age, talk about easy!

 

Valve Body to Case Seals:

     These are a common and greatly overlooked leak point, as a solution, we offer all 3 anew to prevent this concern in your build. They are very easy to install and the replacements provided in this product are true OEM replacements, not cheap imported alternatives that we have discovered are more prone to failure.

 

"Formula One” Billet Accumulator Pistons:

     You can think of accumulator pistons as the shock absorbers of the Valve Body. They’re designed to help regulate pressure during clutch application. The factory units are hunks of plastic Chinese horse-shit that lead to catastrophic failure of the transmission along with abysmal shift quality. We designed our “Formula One” Accumulator pistons here in-house to present a perfect seal and make bore wear a thing of the past.

     These pistons feature an industry leading FIVE seals per piston. Further, the tolerances are set to 0.001” of piston clearance on each side after the rings have sized in, making them a truly flawless fit. These pistons (and frankly all of the parts in this kit) are what enable us to offer a LIFETIME WARRANTY on our Formula One Billet Valve Body. These pistons are a change you can feel!

 

Conclusion:

     If you’re looking for a DIY solution to your 545RFE that does not require a transmission drop, tremendous shop labor costs or going broke, there’s is no better product than our Bulletproof545 kit. This bestselling product is easy to install, affordable and delivers huge improvements to the 545RFE at any mileage or rebuild.
