How Quality Testing Is Done on Our Remanufactured Transmissions

When you purchase a remanufactured transmission, reliability and performance matter just as much as price. At Eagle Engine Sales, quality testing is not a final checkbox—it’s built into every step of our remanufacturing process. From complete disassembly to full dynamometer testing, each transmission is restored and verified to meet or exceed original factory standards.

This is what truly sets a remanufactured transmission apart from a used or simply rebuilt unit.

What “Remanufactured” Really Means (Remanufactured Transmission vs Rebuilt)

A true remanufactured transmission is not the same as “used” or “rebuilt.” While rebuilt transmissions may only replace visibly worn components, remanufacturing is a comprehensive, start-to-finish process.

A remanufactured transmission—often referred to as a reman—is meticulously restored to like-new condition using a combination of new, reconditioned, and OEM-quality components. Every internal system is evaluated, corrected, and tested to ensure long-term reliability.

At Eagle Engine Sales, our remanufactured transmissions include:

• Complete tear-down and inspection

• New or reconditioned OEM-quality components

• Precision machining

• Replacement of critical internal parts

• Reassembly to factory specifications (or better)

• Full quality-control testing prior to shipment

What to avoid: transmissions that are simply cleaned, resealed, or resold without comprehensive rebuilding and performance testing.

Our Step-by-Step Remanufactured Transmission Quality Testing Process

Quality control begins long before final testing. Every transmission follows a strict, documented inspection and testing procedure.

1. Complete Disassembly and Cleaning of Remanufactured Transmissions

Each transmission is fully disassembled down to the bare case. All components are thoroughly cleaned, and transmission cases are media blasted to remove debris, residue, and surface imperfections. This ensures accurate inspection and proper sealing during reassembly.

2. Detailed Internal Component Inspection

Every internal part is inspected for wear, damage, or fatigue. Components that do not meet specifications are replaced—not reused.

• Internal parts are inspected and replaced as required

• All bushings are inspected and replaced as needed

• Drum assemblies are air-checked

• Side play is measured to ensure proper clearance

3. Heavy-Duty Friction Components and Sealing Systems

To improve durability and performance, all friction-related components are replaced.

• 100% of friction components are upgraded with heavy-duty materials

• 100% of seals, O-rings, and gaskets are replaced to prevent leaks and pressure loss

4. Electrical and Hydraulic System Testing

Modern transmissions rely heavily on electronics and precise hydraulic control. These systems are carefully tested and verified.

• 100% of solenoids are tested and replaced if they fail duty cycle requirements

• Internal wiring harnesses are inspected and replaced as necessary

• Valve bodies are completely disassembled and cleaned

• Valve bores are measured for wear and machined when required

• Valve body valves and bores are restored to proper tolerances

Once rebuilt, valve bodies are tested independently to confirm proper operation before being installed in the transmission.

5. Precision Reassembly to Factory Specifications

After all components pass inspection, transmissions are reassembled with precision.

• End plays are carefully set

• All fasteners are torqued to exact factory specifications

• Assembly is verified against original design tolerances

This step ensures smooth operation, proper lubrication, and long service life.

6. 100% Dynamometer (Dyno) Testing for Performance Verification

Every remanufactured transmission undergoes full dynamometer testing prior to shipment.

This critical test simulates real-world driving conditions to verify:

• Proper hydraulic pressures

• Accurate and smooth shift quality

• Consistent performance throughout the operating range

If a transmission does not meet specifications during dyno testing, it is removed, corrected, and retested until it passes.

Why Remanufactured Transmission Quality Testing Matters

Skipping steps in the remanufacturing process can lead to premature failure, poor shift quality, and costly downtime. At Eagle Engine Sales, our rigorous quality testing ensures that every remanufactured transmission delivers dependable performance from day one.

By combining expert craftsmanship, precision machining, upgraded components, and 100% dynamometer testing, we provide transmissions you can trust—backed by strong warranties and nationwide support.
