Digi-Gear PnP Magnum XL Interface for 2019+ S550 Mustang GT
Digi-Gear’s flagship product is a plug‑and‑play electronics interface that allows owners of 2019+ S550 Mustang GTs to run a Tremec Magnum XL transmission without sacrificing factory functionality. If you’re ready to keep your car but ditch the MT82, this is the missing piece that makes the swap behave like it belongs in the car from the factory.
Plug-and-Play Harness & Module
At the core of our solution is a PnP harness and control module designed specifically for the 2019+ S550 Mustang GT platform. It connects directly to your factory wiring with OEM‑style connectors—no cutting, splicing, or guesswork. The module translates the signals your car expects from the original transmission to work correctly with the Magnum XL, keeping control modules and warning systems happy.
Preserve the Features You Love
Modern S550s are full of integrated tech, and a typical transmission swap can confuse the electronics. The Digi-Gear interface is engineered to preserve key factory functions tied into the drivetrain, so you don’t lose the features you bought the car for when you upgrade the gearbox. Our goal is simple: let you enjoy the strength and shift feel of a Magnum XL while keeping the modern behavior and refinement of your 2019+ Mustang.
Magnum XL-Ready Design
This product is purpose‑built around the needs of a Magnum XL swap. Rather than adapting a universal box or relying on a patchwork of solutions, we’ve designed Digi-Gear specifically to make the Magnum XL and your S550’s electronics play well together. That focus means cleaner integration, fewer surprises, and a simpler install for you or your shop.
Quality Components, Enthusiast-Grade Engineering
Every Digi-Gear unit is built with high-quality components, including robust wiring, proper shielding, and durable connectors chosen for long-term reliability. Each harness and module is tested before it leaves our hands. If it wouldn’t meet our standards for use in our own cars, it doesn’t ship. This attention to detail helps ensure your swap is not only functional but also dependable.
Documentation & Support
Your Digi-Gear product comes with clear installation documentation and access to support from people who understand S550 Mustangs and the Magnum XL swap. While we always recommend working with a qualified installer for drivetrain work, we’ve done everything we can to make the electronic side of the swap straightforward. If questions arise, we’re here to help you get your car up and running the way it should.
If you’re ready to lose the MT82 without losing the car you love, the Digi-Gear PnP Magnum XL Interface for 2019+ S550 Mustang GTs is your solution.
