ATS Diesel – 68RFE / AS69RC Thermal Bypass Valve Up-Grade (3100052392)

It’s important to note that this is not a full valve body replacement, but rather a critical thermal bypass valve upgrade that addresses cooling efficiency. The OEM thermal bypass restricts flow to the cooler until fluid reaches a high temperature, which is detrimental to transmission longevity, especially under load. This ATS kit eliminates that restriction, providing constant, maximized cooling flow.

Key features that stand out:
ATS Thermal Bypass eliminates cooling restriction
2 Quick Release Cooler Line Fittings (for applicable years)
ATS 68RFE Billet Aluminum Filter Coupler

Comparison Insights: Finding the Right 68RFE Upgrade

Choosing the best 68rfe valve body upgrade depends heavily on your budget, your truck’s model year, and your power goals.

When reviewing the options, the most significant distinction is between full valve body replacements (like Revmax 68RFE-301A) and internal upgrade kits (like the Revmax Foundation Kit). A full replacement is generally recommended for high-mileage or heavily abused transmissions, while the Foundation Kit is best for refreshing a relatively healthy unit.

The ZeroFlex/Billet units (Products 2, 3, 7) offer an engineering advantage over traditional cast or upgraded units. Billet channel plates eliminate warping, which is the single biggest cause of chronic line pressure loss in high-heat situations. If you push big power or tow constantly in hot climates, the billet option is often worth the extra investment for superior durability.

Finally, remember that the Thermal Bypass Upgrades (Products 4 and 8) are essential supplementary modifications. While they don’t fix soft shifts, they are critical for transmission longevity by maximizing cooling efficiency, particularly in towing applications. Installing a high-performance valve body without addressing cooling is leaving half the job undone.

Final Verdict: Which Upgrade Delivers the Most Value?

When selecting the best 68rfe valve body upgrade, we must break down the winners by category:

For the Extreme Durability Buyer (Unlimited Budget): The RevMax ZeroFlex 68RFE Billet High Performance Towing/HD Valve Body (Product 2) wins hands-down. Its inclusion of the OEM solenoid combined with the unparalleled flatness of the billet construction makes it the gold standard for high-horsepower or sustained heavy towing.

For the Best All-Around Performance and Value (2011-2018): The Revmax 68RFE High Performance Towing/HD Valve Body (Product 1) provides a massive performance boost by addressing the critical SSV failure point with steel components and providing crisper shifts, all at a reasonable price point for a complete unit.

The Essential Companion Upgrade: You must integrate the Thermal Bypass Valve Upgrade (Product 4 or 8, depending on year) into your plans. No matter which valve body you choose, minimizing heat is crucial for the 68RFE’s survival.

Common Questions About Best 68RFE Valve Body Upgrade

What are the main problems with the stock 68RFE valve body?

The stock 68RFE valve body suffers primarily from inadequate material strength and poor hydraulic sealing under high pressure and heat. The most infamous issue is the Solenoid Switch Valve (SSV), which is typically plastic and can wear prematurely, leading to a significant loss of line pressure and eventual clutch failure. The thin separator and channel plates can also warp, causing internal cross-leaks and soft, slipping shifts.

Does upgrading the valve body require transmission tuning?

In most cases, yes, tuning is highly recommended, especially when installing a high-performance unit designed for faster, firmer shifts. While some upgraded valve bodies can be run without tuning, transmission control module (TCM) tuning allows you to precisely match the shift scheduling and line pressure targets to the capabilities of your upgraded valve body, ensuring optimal performance and shift quality.

Is a billet aluminum valve body necessary?

While not strictly required for a stock truck, a billet aluminum channel plate (like the ZeroFlex models) is highly beneficial, particularly for trucks that tow heavily or have power enhancements. Billet aluminum is significantly more rigid than cast aluminum, meaning it resists warping under extreme heat and pressure. This prevents critical line pressure loss, greatly improving the transmission’s longevity and shift consistency.

How difficult is it to install a new 68RFE valve body?

Installing a valve body is generally considered a moderate to difficult job. It requires draining the fluid, dropping the transmission pan, and carefully managing the electrical connections (solenoid plug). Precision and cleanliness are paramount. While a skilled DIY mechanic can perform the replacement in a garage, complex internal kits (like the Foundation Kits) or full billet replacements might be better handled by a specialized transmission shop to ensure proper torque sequences and sealing procedures are followed.

What is the benefit of including a new OEM solenoid assembly?

The solenoid pack is the electrical brain of the 68RFE, controlling hydraulic pressure via electronic signals. These packs can be expensive and sensitive. Choosing a valve body that includes a new OEM solenoid assembly saves time, guarantees immediate compatibility, and eliminates the risk of reusing an old, worn, or potentially failing solenoid on your new performance valve body.

Will a high-performance valve body cause rough shifting?

A properly designed performance valve body will result in shifts that feel firmer and quicker, especially when accelerating hard or towing. This firmness is intentional—it minimizes clutch slip, reducing heat and wear. While you may notice the shifts more than stock, they should feel crisp and precise, not harsh or jarring. If the shifts feel excessively rough, it often indicates an issue with TCM tuning or line pressure calibration.
