Installation Available
Installation Available by our Team of Experts.

What we do differently
Hotflush Technology for a Clean Start
When installing, RedLine uses Hotflush machine technology to thoroughly clean transmission cooler lines and systems. This step removes all debris, clutch material, and contaminants that could damage a fresh build—something many shops skip. A clean system means your new transmission runs the way it should from day one.
Precision Install & Calibration
RedLine doesn’t just “bolt it in.” Every installation includes careful alignment, torque checks, and electronic calibration specific to your truck. We verify line pressures, fluid levels, and TCM settings so the transmission communicates perfectly with your engine and drivetrain.
Post-Install Testing & Validation
Before handing the keys back, RedLine performs road tests, relearn procedures, and live diagnostics to confirm drivability, shift quality, and overall performance. This ensures your truck leaves ready to work or play—without you being the test driver.
How RedLine Builds It Better!
Expert Craftsmanship
Every transmission is hand-built by seasoned builders who understand the difference between “good enough” and “bulletproof.” 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 (THE 450, THE 550, THE 700, THE 1000, etc.) 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.
