Get a Complete Transmission Build Estimate
Expert Guidance. Accurate Pricing. Let’s See If We’re the Right Fit.
When your transmission starts slipping, shifting hard, or holding you back, waiting only makes the problem worse. A complete transmission estimate from RedLine Transmissions is the fastest way to understand what your truck truly needs — and whether we’re the right team to build it.
We specialize in Dodge/RAM Cummins, Chevy/GMC Duramax, 68RFE, 47RE/48RE, Allison 1000, and high-performance diesel builds designed for towing, daily driving, work fleets, and horsepower upgrades. Every build is crafted using our proven RedLine blueprint — but the first step is making sure your goals and our expertise align.

To See If We’re the Right Fit to Work Together
Every truck and every customer is different. This form helps us learn about your build, your upgrades, how you use your truck, and what you expect from your transmission. We want to make sure we can deliver the reliability, performance, and longevity you’re looking for.
Get Matched to the Correct Build — No Guessing Required
Horsepower, towing habits, and truck setup all determine the best transmission for your build. We use your details to recommend a package that fits your truck — not a generic one-size-fits-all option.
Ensure You Don’t Overbuild or Underbuild
Choosing the wrong transmission costs you money, time, and future repairs. Our estimate helps you select the right build the first time.
Transparent, Accurate Pricing From Experts
Your estimate includes full build pricing, shipping or installation options, warranty details, and any core information — all reviewed by a real RedLine specialist, not an automated system.
