Guangzhou Meishun Automatic Transmission Co., Ltd. Company Profile

Automatic Transmission Remanufacturing Process

1. Disassembly Line

   • Transmission Dismantling: Fully disassemble transmissions into individual components using a dedicated dismantling conveyor line.

2. Cleaning Process

   • Initial Cleaning: Degrease and remove contaminants via mechanical washing machines (e.g., ultrasonic or high-pressure systems).

   • Manual Cleaning: Detailed hand-cleaning of complex parts (gears, channels, etc.) to ensure no residue remains.

3. Component Inspection & Testing

   • Solenoid Testing: Check electromagnetic valves (solenoids) with a solenoid tester for proper electrical response and flow rates.

   • Valve Body Testing: Validate hydraulic performance and pressure regulation using a valve body test machine.

4. Refurbishment

   • Housing Restoration: Clean and refinish transmission casings/housings using sandblasting/painting machines.

   • Hardware Assembly: Reinstall bolts/fasteners with automated screw installation machines for torque precision.

   • Accumulator Charging: Recharge accumulators with nitrogen using a dedicated accumulator charging machine.

5. Rebuilding & Coding

   • Reassembly: Rebuild transmissions with refurbished/new components following OEM specs.

   • Laser Marking: Apply traceability codes/serial numbers via laser marking machine.

6. Final Validation

   • Vehicle Integration Test: Install transmissions in test vehicles or dynamometers to verify performance under real-world conditions (shifting, pressure, leaks, etc.).

7. Packaging & Shipping

   • Prepare certified remanufactured units for delivery.

Research & Development (R&D) Capabilities

We specialize in custom remanufacturing of automatic transmissions across multiple brands and models. Our in-house R&D team designs, adapts, and tests transmissions to meet client specifications, ensuring compatibility and performance.

Key Features:

• Tailored Solutions: Modify gear ratios, torque capacity, or control software for unique applications (e.g., performance, off-road, or commercial vehicles).

• Prototyping & Testing: Rigorous validation using solenoid/valve body testers and dynamometers before shipment.

• OEM+ Standards: Rebuild beyond factory specs with upgraded materials/components where needed.

Quality Assurance & Warranty

• Pre-Delivery Testing: Every unit undergoes real-world simulation (via test vehicles/dynos) to guarantee reliability.

• 1-Year Warranty: Backed by a 12-month warranty covering defects in materials and workmanship.
