Protect Your Remanufactured Transmission – Why a Bypass Delete Kit Is a Must-Have!
Investing in a remanufactured transmission? Learn why a bypass delete kit is a crucial add-on to prevent overheating, improve fluid flow, and extend transmission life.
Introduction: Protecting Your Investment in a Remanufactured Transmission
Purchasing a remanufactured transmission is a significant investment, often costing between $2,500–$5,000. While remanufactured units offer improved durability and updated components, one critical issue remains—the factory-installed transmission bypass valve.
Many modern transmissions, including the 6L80 (GM), 6F35 (Ford), and 68RFE (Ram/Chrysler), come with a built-in bypass valve that restricts transmission fluid flow to the cooler. While originally designed for temperature regulation, this system often causes overheating, fluid starvation, and premature failure—even in freshly rebuilt transmissions.
Installing a bypass delete kit eliminates these risks, ensuring your remanufactured transmission stays cool, runs efficiently, and lasts longer. In this article, we’ll break down why this small upgrade is a huge benefit for anyone buying a remanufactured transmission.
What Is a Bypass Delete Kit and How Does It Work?
A bypass delete kit is a simple aftermarket upgrade that removes the factory bypass valve, allowing transmission fluid to flow continuously through the cooler.
What’s Included in a Bypass Delete Kit?
A replacement adapter that eliminates the factory bypass valve.
Upgraded fittings to ensure proper fluid pressure.
Seals and gaskets to prevent leaks.
By installing this kit, your transmission fluid is always routed through the cooler, preventing overheating and reducing thermal stress on critical components.
Why a Bypass Delete Kit Is Crucial for Remanufactured Transmissions
While a remanufactured transmission comes with fresh components and quality upgrades, it’s still vulnerable to the same cooling system flaws as the original unit.
Here’s why installing a bypass delete kit should be your first upgrade after purchasing a remanufactured transmission:
1. Protects Against Overheating
A remanufactured transmission still needs proper cooling to prevent fluid breakdown, clutch wear, and overheating-related failures. The stock bypass valve can cause temperature spikes, but a bypass delete kit keeps the transmission cool at all times.
2. Ensures Consistent Fluid Flow
Many factory bypass valves restrict transmission fluid flow, leading to erratic cooling and potential fluid starvation. A bypass delete kit eliminates these restrictions, ensuring transmission fluid flows smoothly and consistently.
3. Prevents Common Bypass Valve Failures
Bypass valves frequently fail due to:
Clogs from debris and metal shavings
Wear and tear over time
Getting stuck in an open or closed position
If the valve sticks closed, your remanufactured transmission may overheat rapidly, causing internal damage and failure. A bypass delete kit removes this failure point entirely.
4. Extends the Life of Your Remanufactured Transmission
By maintaining stable operating temperatures and proper lubrication, a bypass delete kit helps:
Reduce wear on clutches, solenoids, and gears
Prevent premature fluid degradation
Extend the transmission’s lifespan by thousands of miles
Considering a remanufactured transmission already costs thousands of dollars, this affordable upgrade (usually $50–$150) is a small price to pay for long-term reliability.
5. Ideal for Towing, Heavy Loads, and Performance Vehicles
If you tow heavy trailers, off-road, or push your vehicle to its limits, a bypass delete kit significantly improves performance by keeping the transmission fluid at a safe operating temperature.
Bonus: Many towing professionals and performance tuners recommend this upgrade immediately after installing a remanufactured transmission!
How to Install a Bypass Delete Kit on a Remanufactured Transmission
Installing a bypass delete kit is a straightforward process that can be done at home or by a professional.
Tools Needed:
Wrench set
Thread sealant
Transmission fluid catch pan
Step-by-Step Installation:
1 Drain a small amount of transmission fluid to avoid spills.
2 Locate and remove the stock bypass valve.
3 Install the bypass delete adapter and secure fittings.
4 Check for leaks and ensure proper sealing.
5 Refill transmission fluid to the correct level.
