ATS Diesel 2013-2018 Ram Cummins 6.7L w/ 68RFE or Aisin AS69RC Trans Thermal Bypass Valve Upgrade
The ATS Diesel Thermal Bypass Valve Upgrade replaces the factory valve on 2013-2018 Ram trucks equipped with 6.7L Cummins diesel engines and 68RFE or Aisin AS69RC transmissions.
This direct-fit component uses a high-flow thermostat to bypass the transmission cooler during cold starts, directing fluid internally until optimal temperature is reached. It then fully engages the cooler to dump heat efficiently, reducing wear on clutches and seals while extending fluid life and improving shift quality under load.
Key Features
- CNC Machined Billet Aluminum Housing: Precision-machined from 6061-T6 aluminum with black anodized finish for corrosion resistance and durability in harsh conditions.
- High-Flow Brass Thermostat: Opens fully at 170 degrees F for rapid heat dissipation, preventing fluid oxidation and maintaining consistent performance during towing or high-stress use.
- Stainless Steel Spring and O-Rings: Provides reliable sealing and consistent bypass operation across thousands of cycles, eliminating factory plastic failures.
- Direct Bolt-On Design: Matches OEM mounting points with no modifications, ensuring simple installation and perfect integration with stock cooler lines.
- Enhanced Fluid Management: Warms transmission fluid 30 percent faster than stock, reducing initial wear and enabling crisper shifts from a cold start.
Product Notes
- Requires no transmission disassembly. installs in under 30 minutes with basic hand tools.
- Use with full-synthetic ATF for best results and to maintain warranty coverage.
- Packaged securely to prevent damage. handles standard ground shipping without issues.
Installation Notes
- Professional installation recommended.
- Drain minimal fluid from cooler line before removal. torque to 20 ft-lbs.
- Compatible with all factory and aftermarket cooler line fittings. no adapters needed.
