Randy's Transmissions

What Randy's Transmissions does

Randy's Transmissions is a privately held, Utah-based retailer and rebuilder of high-performance diesel automatic transmissions and supporting drivetrain components. Founded in 2008 and headquartered in West Valley City, Utah with an additional Tooele location, the company targets Dodge/Ram (Cummins), Chevy/GMC (Duramax), and Ford (Powerstroke) light- and heavy-duty pickup platforms. Core offerings are platform-specific rebuilt transmissions (47RE, 48RE, 68RFE, AISIN AS69RC, Allison 1000, 6R140, 5R110W, 10R140) ranging from stock replacements to Stage 4 builds rated for 1,000+ horsepower, paired with proprietary BabyMaker valve bodies, billet torque converters, deep pans, plug-and-play DIY rebuild kits, service kits, and transmission coolers. Each build carries published, tested horsepower ratings, and product R&D is conducted in partnership with industry specialists.

The business model is direct-to-consumer e-commerce supplemented by a domestic stocking dealer network and dealer locator program. Pricing is per-unit with a wide spread from $9 for small ancillary components to $16,525 for top-tier Stage 4 transmissions, and consumer financing is offered through Affirm. Customer mix is bifurcated between diesel truck enthusiasts and performance builders (primary) and commercial fleet operators (secondary). The company is privately held with 1-10 employees, no disclosed funding, no patents, and no public financial statements.

In December 2025 the company announced a coast-to-coast U.S. expansion alongside the onboarding of industry veteran Frank Kuperman Jr. as part owner, the establishment of new headquarters, and the launch of new product lines. These moves represent the most significant strategic shift in the company's history and signal an intent to scale beyond a regional specialist footprint.
