How RedLine Builds It Better!
Expert Craftsmanship
Every transmission is hand-built by seasoned builders who understand the difference between “good enough” and “overbuilt.” We believe in going the overbuild route. Instead of rushing jobs or using cookie-cutter rebuild kits, RedLine takes the time to precision-machine, measure, and assemble each unit so it’s tuned to last tens of thousands of miles under real-world stress.
Specific Brand & Platform Knowledge
You don’t just “do transmissions.” You specialize in Cummins Dodge/RAM and Duramax Chevy/GMC platforms, which means you know the quirks, weak points, and exact part combinations that actually work in these trucks. This expertise ensures builds are not only stronger but also tailored for each application—whether it’s towing, daily driving, or performance horsepower.
Proprietary Build Recipes & Tested Combinations
RedLine has developed its own proven build recipes (ROAD BOSS 450, TOW BOSS 550, HD BOSS 700, TRACK BOSS 900 and 1200 COMPETITION BOSS) that eliminate factory weak points and balance performance with durability. These aren’t off-the-shelf packages—they’re field-tested setups refined over thousands of transmissions, backed by real-world data and customer feedback.
Real-World Testing & Validation
Before a RedLine transmission goes out the door, it’s not just assembled—it’s tested, validated, and proven under real-world conditions. From line pressure checks to hot flush verification and test-drives, every unit is verified to perform the way it should. This extra layer of quality control ensures customers drive away with confidence, knowing their build has already been put through its paces.
Craftsmanship Warranty
We believe peace of mind matters just as much as performance. That’s why our all our transmission builds include up to a 24-month, unlimited-mile warranty—so you can drive, tow, and enjoy your truck with confidence.
Fun Fact: The longest running RedLine transmission has over 500,000 miles on the build and it STILL on the road to this day!
