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

It is important to note that the ATS Diesel product here is a Thermal Bypass Valve Up-Grade, not a complete valve body. However, it is an absolutely essential companion upgrade for anyone installing a performance valve body. The factory thermal valve restricts flow to the cooler when fluid is cold, but often stays restricted even when hot, leading to excessive transmission fluid temperatures. This ATS bypass kit ensures maximum cooling efficiency, which dramatically extends the life of your new performance best 68rfe valve body and transmission clutches.

Key features that stand out:
* Function: Ensures maximum oil flow to the transmission cooler.
* Components: ATS 68RFE Billet Aluminum Filter Coupler.
* Benefit: Dramatically lowers operating transmission fluid temperatures.
* Installation: Includes necessary quick-release cooler line fittings.

Pros:
* Crucial for maximizing transmission longevity, especially when towing or using performance tuning.
* Easy installation compared to a full valve body swap.
* Billet aluminum construction for durability.

Cons:
* It is an add-on product and does not replace a damaged valve body itself.

Best for: Anyone installing a high-performance valve body (like a Revmax unit) or those who experience consistently high transmission temperatures when towing.

Expert Opinion: This is often the first non-performance upgrade recommended by transmission experts because poor cooling renders even the best 68rfe valve body ineffective over time.

Comparison Insights: Finding the Right Upgrade

When looking for the best 68rfe valve body, your choice usually comes down to performance requirements versus budget constraints.

For Peak Performance and Durability:
The RevMax ZeroFlex 68RFE Billet High Performance units (Product 2 and Product 4) are undisputed leaders. The use of billet aluminum guarantees flatness and virtually eliminates internal leakage. If budget allows, choosing the version that includes the Authentic OEM Solenoid Assembly (Product 2) is the most straightforward high-performance install.

For Reliable Repair and Best Value:
The remanufactured options like the Shift Rite Transmissions replacement (Product 9) offer incredible value. The fact that it fixes the common TCC bore wear and comes with a lifetime warranty makes it a smart long-term investment for reliable use, even if it doesn’t offer the extreme performance gains of a billet unit.

For Specialized Needs and Proactive Maintenance:
If you have a newer 2019+ truck, the RevMax 68RFE Valve Body Foundation Kit (Product 6) is ideal for strengthening your existing componentry without a complete overhaul. Also, remember that any performance valve body installation should be paired with the ATS Diesel Thermal Bypass Valve Up-Grade (Product 10) to manage heat effectively.

Final Verdict: Our Top Choices for the Best 68RFE Valve Body

Selecting the absolute best 68rfe valve body depends entirely on your specific truck usage:

The Uncompromising Performance Winner:
For the serious enthusiast or heavy commercial tower who needs maximum line pressure stability and shift speed, the RevMax ZeroFlex 68RFE Billet High Performance Towing/HD Valve Body (with OEM Solenoid) is the definitive choice. Its precision engineering and complete package make it worth the investment.

The Best All-Around Value and Peace of Mind:
If reliability and warranty are your primary concerns, the Shift Rite Transmissions REMANUFACTURED VALVE BODY is highly recommended. You get a professionally fixed unit that corrects OEM flaws, backed by a lifetime warranty—a major factor in transmission components.

The Best Budget-Conscious Replacement:
For basic repairs on older models or budget-focused fixes, the standard refurbished units like 45RFE 545RFE 68RFE Refurbished Transmission Valve Body offer tested, functional replacements without the high cost of billet performance.

Common Questions About the Best 68RFE Valve Body

What are the main symptoms of a failing 68RFE valve body?

A failing valve body often manifests as delayed or erratic shifts, flare-ups between gears (RPM increases briefly without acceleration), loss of forward or reverse gears, and general “soft” or spongy feeling shifts. In many cases, it will also trigger diagnostic trouble codes related to solenoid performance or clutch slippage due to insufficient line pressure.

Do I need to replace the solenoid pack when installing a best 68rfe valve body?

While some performance valve bodies (like many Revmax models) can be used with a known good, low-mileage factory solenoid, it is highly recommended to install a new solenoid pack simultaneously. The solenoid pack is crucial for precise hydraulic control and is often a failure point itself. Products that include a new OEM solenoid, like the ZeroFlex package, save time and ensure peak performance right out of the box.

Will installing an aftermarket 68RFE valve body require custom tuning or programming?

Generally, a high-quality aftermarket or remanufactured best 68rfe valve body designed to maintain OEM parameters (like many plug-and-play refurbished options) will not require new tuning. However, performance-oriented valve bodies that significantly raise line pressure or change shift timing (like the Revmax HD models) will benefit greatly from a Transmission Control Module (TCM) tune. This tune maximizes the performance gains and ensures the TCM is commanding the correct pressure for the upgraded components.

What is the difference between a billet valve body and a remanufactured one?

A remanufactured valve body is a used OEM unit that has been completely disassembled, cleaned, inspected, and rebuilt with new seals, valves, and components, often correcting known factory defects (like the Shift Rite unit). A billet valve body, like the RevMax ZeroFlex, is manufactured entirely from a solid block of aluminum (6061 billet). Billet construction offers superior dimensional stability and flatness, which is vital for high-pressure, high-performance applications.

How does the 68RFE thermal bypass valve upgrade (Product 10) work with a new valve body?

The stock thermal bypass valve often restricts fluid flow to the transmission cooler until the fluid is very hot. The ATS thermal bypass valve upgrade permanently opens the cooler circuit or lowers the activation temperature, ensuring maximum transmission fluid cooling at all times. By keeping the fluid cooler, you protect the seals, solenoids, and clutch packs in your new valve body, increasing the overall lifespan of the transmission.

What causes the failure of the original 68RFE solenoid switch valve (SSV)?

The original SSV is prone to wear, especially in high-mileage or high-heat conditions. This wear is often due to the soft material used in the OEM valve combined with constant cycling and poor filtration. Once the bore wears, line pressure leaks past the valve, leading to reduced clutch holding power and eventual transmission damage. Upgrading to a billet steel SSV (a feature in many Revmax products) eliminates this common failure.
