Understanding the Solenoid Switched Valve in the 68RFE

May 29, 2026
Understanding the Solenoid Switched Valve in the 68RFE Transmission: Common Problems & How Apex Transmission and Auto Fixes Them The 68RFE transmission is a popular choice for many Ram trucks, known for its reliability and smooth shifting. However, like any transmission, it has its weak points — one of the most common being issues related to the solenoid switched valve . At Apex Transmission and Auto , we specialize in diagnosing and resolving these problems using industry-leading solutions like the TransGo valve body kit. What Is the Solenoid Switched Valve? The solenoid switched valve is a critical component inside the 68RFE valve body. It works with the transmission’s solenoids to regulate hydraulic pressure and control the engagement of various clutches and bands. Proper function of this valve ensures smooth and timely gear shifts. Common Problems Caused by the Solenoid Switched Valve When the solenoid switched valve begins to fail or malfunction, you might notice a range of issues, such as: Harsh or delayed shifts: The transmission may hesitate or shift roughly between gears, especially during 2-3 or 3-4 shifts. Transmission slipping: Inconsistent hydraulic pressure can cause the transmission to slip under load. Check Engine Light and transmission error codes: Error codes related to solenoid malfunctions or pressure irregularities often point back to the solenoid switched valve. Transmission overheating: Improper valve function can increase heat generation, risking damage to internal components. How Is the Solenoid Switched Valve Problem Fixed? At Apex Transmission and Auto , we know that simply replacing solenoids or the valve body isn’t always enough. The solenoid switched valve requires precision reconditioning and upgrades to restore reliable function. Our technicians utilize the TransGo valve body kit , a high-quality aftermarket solution specifically designed to improve hydraulic control and shift quality. The TransGo kit includes: Precision-machined components to replace worn or damaged valves Enhanced springs and seals for better pressure management Upgraded valves that reduce common failure points By installing the TransGo kit and performing a full valve body rebuild, we eliminate the root causes of many solenoid switched valve problems, resulting in smoother shifts, improved durability, and extended transmission life.

The dreaded 6l80/90 shudder crisis

May 29, 2026
The Shudder Crisis: What’s Going On with the 6L80E & 6L90? If you own a GM vehicle with a 6L80E or 6L90 transmission, chances are you’ve felt it — that irritating, rhythmic vibration while cruising between 30–50 mph. Known in the performance and repair world as “ The Shudder Crisis ,” this issue is more than just a comfort concern — it’s a warning sign. At the root of the problem is torque converter clutch (TCC) shudder. It’s typically caused by degraded transmission fluid or worn TCC components, but factory tuning also plays a major role. GM’s original torque converter schedule keeps the clutch engaged too early and too often, especially under light load — causing premature wear and frequent shudder. The Real Fix: More Than Just Fluid While upgrading to Mobil 1 LV ATF HP fluid can help reduce shudder, it’s often not enough for long-term reliability. That’s where TransGo’s drop-in valve kit and a Coode-modified tune come in. TransGo TCC Regulator & Boost Valves: These upgrade the hydraulic integrity of the transmission, preventing pressure loss and improving converter clutch control. Code-Mod Tune: Custom tuning recalibrates the torque converter schedule to reduce unnecessary clutch application, minimize heat, and eliminate early lockup. Together, this combo solves the issue at its source — not just masking it. The result? A smoother drive, better longevity, and peace of mind. Dealing with shudder? Don’t wait for major damage. Upgrade with precision hardware and proven tuning. Contact us to learn more.
