2023 Ram TRX Engine and Transmission Package at McClain Auto Part

The Ram 1500 TRX sits at the top of what factory performance trucks offer. The supercharged 6.2L HEMI Hellcat engine paired with the 8-speed automatic transmission is one of the most capable factory drivetrain packages ever put into a production pickup truck. When buyers search for this drivetrain they are not looking for a generic replacement. They want the complete package, low mileage, inspected, and from a seller who understands what they are buying.

At McClain Auto Part we have been sourcing and selling high-performance drivetrains since 2009. The TRX engine and transmission package is one of the most specialized units we handle and we approach it that way. Buyers come to us for several reasons. A collision-damaged TRX that needs a full drivetrain replacement. A rebuild project where the original engine sustained internal damage. Custom swap builds where the Hellcat truck platform is the target. Whatever the application, we stock verified units, inspect every component, and back every sale with a 6-month warranty.

This is not a common used engine listing. The TRX drivetrain is expensive, complex, and the buyers who need it know exactly what they are looking for. We make sure what we ship matches what we represent.

What Makes the TRX Drivetrain Different

The supercharged 6.2L HEMI in the Ram TRX is the same fundamental engine architecture that powers the Hellcat Challenger and Charger, adapted for a heavy duty truck application. The supercharger setup is roots-type positive displacement, which means boost is available immediately across the RPM range rather than building progressively like a turbo. That characteristic is part of what makes the TRX feel different from turbocharged performance trucks.

The 8-speed TorqueFlite automatic transmission paired with the TRX engine is built to handle the output. Shift speeds, torque capacity, and thermal management are all calibrated for the supercharged application. This is not a standard Ram 1500 transmission pressed into service on a high output engine. It is spec’d for the job from the factory.

The combination produces 702 horsepower and 650 lb-ft of torque in factory trim. For a truck that weighs over 6,000 pounds that is a significant achievement and it explains why the TRX drivetrain is sought after for both factory replacements and swap projects.

Condition and Inspection Process

The TRX drivetrain carries a significant value and the buyers who order it expect it to arrive in the condition described. We inspect every unit at our Cleveland facility before it ships.

What We Check Before Every TRX Package Ships

• Compression tested on every cylinder with actual numbers recorded
• Supercharger housing inspected for cracks, rotor condition, and boost seal integrity
• Intercooler and charge air system inspected for damage and contamination
• Full visual inspection of the engine block, heads, and external components
• Oil passages checked for contamination and signs of deferred maintenance
• Coolant system inspected for signs of head gasket issues or mixing
• Transmission fluid inspected for metal contamination and condition
• Transmission shift quality assessed through bench testing where applicable
• Mileage verified against donor vehicle records
• No knocking, no ticking, no unusual engine noise confirmed before packaging

The supercharger is the component we focus on most thoroughly beyond standard engine inspection. Rotor clearances, bearing condition, and seal integrity all affect boost delivery. A supercharger that passes our inspection is one that should deliver the boost the engine was calibrated for.

Primary Application

• 2023 Ram 1500 TRX, factory supercharged Hellcat application

Direct TRX Replacement

For buyers replacing a damaged or seized drivetrain in a 2023 Ram TRX, this package is a direct replacement. Confirm your VIN and current drivetrain configuration with us before ordering. The TRX uses specific motor mount locations, driveshaft angles, and ECU calibration that differ from standard Ram 1500 applications.

Swap Applications

The TRX drivetrain is increasingly sought after for custom swap projects. The Hellcat engine architecture is well documented and the swap community around it is active. However this is a complex integration. The 8HP95 transmission requires electronic control integration that is specific to the Hellcat platform. The supercharger drive, ECU, wiring harness, fuel system requirements, and cooling demands all need to be addressed in a swap application.

We are happy to talk through what a swap project involving this drivetrain requires before you order. Call us and we give you a straight answer about what is involved.

The TRX Drivetrain for Performance Builds and Swaps

The TRX platform represents the most accessible factory Hellcat truck drivetrain on the used market. Builders who want supercharged V8 performance in a truck application and do not want to engineer a full custom induction system look at the TRX package as a starting point.

The 8HP95 transmission is a robust unit. It handles the factory 702 horsepower application and has shown in the Hellcat community that it tolerates additional power with proper calibration. Builders who plan to push output beyond factory spec with supporting modifications have used this transmission as their foundation.

The electronics integration is the realistic challenge for swap builders. The Hellcat ECU manages boost, fueling, shift points, and stability systems as an integrated package. Separating the engine from its factory management system and integrating it into a different chassis requires purpose-built harness work and calibration. This is not a bolt-in swap for most applications. It is a project that rewards planning.

If you are serious about a TRX-powered build, talk to us before ordering. We want you to have the right expectations going in.

Warranty

Every TRX engine and transmission package we sell comes with a 6-month warranty against internal mechanical defects. If the engine or transmission develops a covered mechanical failure within that period, contact our team. We look at what happened and work toward a fair resolution. Replacement unit, credit, or repair guidance depending on the situation and what is available.

James McClain has been honoring warranty claims since 2009. If it failed because of something on our end, we own it.

Frequently Asked Questions

Is This a Complete TRX Engine and Transmission Package?

Yes. This listing includes both the supercharged 6.2L HEMI engine and the 8-speed TorqueFlite automatic transmission as a package. Call us to confirm exactly what is attached to the specific unit we have in stock before ordering.

Does It Include the Supercharger?

Yes. The supercharger is part of the engine assembly on the TRX Hellcat package. The supercharger is inspected as part of our pre-ship process. Confirm with us that the supercharger is present and in acceptable condition on the specific unit before committing to the order.

How Many Miles Are on This Drivetrain?

Mileage varies by available unit. We verify mileage against donor vehicle records and give you the exact figure before you order. Call us or inquire through our contact page and we provide mileage information on current stock.

Is the Transmission Tested Before Shipping?

Yes. Transmission fluid is inspected for metal contamination, shift quality is assessed where bench testing is applicable, and the unit is visually inspected for leaks and case damage before packaging.

Can This Drivetrain Be Used for Swap Projects?

Yes, though swap integration for the TRX Hellcat drivetrain is complex. ECU, wiring harness, fuel system, cooling, and mounting all require custom work for non-TRX applications. Call us before ordering if you are planning a swap and we talk through what is involved honestly.

What Accessories Are Included With the Package?

Included accessories vary depending on how the drivetrain was removed from the donor vehicle. Wiring harness and standalone ECU are not guaranteed to be included unless confirmed at time of order. Call us before ordering and we tell you exactly what is on the specific package we have in stock.

Does It Come With the ECU or Wiring Harness?

Not unless specifically confirmed. The Hellcat ECU and harness are highly application-specific. If you need these components for a swap or replacement build, let us know when you call and we tell you what we have available with the current unit.
