No stock photos, no borrowed workshop footage. Everything on this page is our own factory in Huadu, Guangzhou — the same benches, the same people, the same process your order goes through. Twenty years of transmission work stands behind every unit.
Meishun has specialised in automatic transmission remanufacturing and supply for 20 years. At our dedicated Huadu facility, units arrive as cores or new castings and leave as tested, crated, code-verified products. In between: teardown, ultrasonic cleaning, press fitting, rebuild and 20 pieces of test equipment.

The main workshop: teardown and rebuild bays, parts cleaning area and press station.
Every remanufactured transmission at our Guangzhou Huadu factory follows a strict, fully standardized procedure — complete component overhaul, professional cleaning, targeted upgrade, precision reassembly and 100% dyno testing — so each unit meets or exceeds OEM quality standards.

All incoming cores are inspected for housing cracks, structural damage and internal failure before production begins. Qualified units are fully disassembled piece by piece, and every component is sorted, recorded and cataloged for traceability.

Planetary gears, shafts, bearings, valve bodies, solenoids and clutch assemblies are all inspected. Worn, deformed, fatigued or out-of-tolerance parts are scrapped — micro cracks, scoring, warping and pressure deviation are eliminated before reassembly.

Reusable metal parts, housings and hydraulic components go through multi-cycle ultrasonic cleaning with specialised solvents, removing carbon buildup, old sludge and metal debris. Every cleaned part then passes a second visual and structural inspection.

Clutch packs, friction and steel plates, seals, gaskets, filters, thrust washers and rubber parts are replaced with OEM-spec components. Model-specific factory weak points are actively upgraded to resolve original design defects.

Bearings, bushings and shaft components are installed on 20-ton hydraulic press equipment to strict OEM pressure and depth standards. Worn valve bores are restored by professional re-sleeving instead of simple polishing.

Solenoids, sensors and valve bodies are electronically and hydraulically bench-tested for oil circuit flow, pressure stability, switching response and leakage. All CVT units get dedicated pulley cylinder pressure testing to rule out internal micro-leakage.

Housings are sandblasted to strip old sealant, rust and surface debris. All sealing surfaces are refinished and precisely prepped to guarantee perfect fitment and zero oil leakage after reassembly.

Reassembly follows OEM technical specifications with standard torque values and professional lubrication. Every component is installed in standardized sequence for mechanical balance, accurate hydraulic control and stable shifting.

Every finished transmission — not a sample — runs full-load dyno testing before shipment: line pressure, clutch engagement, torque delivery, shift quality, operating temperature, hydraulic stability, noise and tightness. All test data is archived for each individual unit.

Each unit is double-checked for model code matching, appearance quality and sealing performance. Qualified units are packed in fumigated export wooden crates with shockproof and moisture-proof treatment, and shipment photos are provided for confirmation.

Workshop, testing lab, showroom, warehouse and office are integrated in one campus. All videos and photos are 100% real on-site footage — global clients are welcome for on-site factory tours or online video-conference inspections.

Warehouse, office, display area and workshop are all integrated in one site. Customers are welcome for on-site factory tours, or online video conference visits upon request.

Same workshop, same crates, same process — filmed end to end. Every order ships with its own packing and loading photos.
Step by step: shockproof wrapping, moisture barrier, foam blocking and the fumigated export crate.
Finished units crated and staged for loading — tracking and shipment photos follow every dispatch.
Workshop, showroom and warehouse are open to customers year-round. Cannot travel? We run the same tour live over video call.

Customers check core stock and finished units shelf by shelf — nothing is hidden behind a catalogue.

Part families on display with the CE certificate wall behind — the visit usually ends with a photo here.

Rebuilders, wholesalers and importers regularly fly in for training and pre-shipment inspection.

Fitment lists, packing photos and test data reviewed together — questions answered by the engineers who built the unit.

Pre-shipment inspection is welcome: buyers verify codes, castings and packaging before the crate is closed.

An independent Production & Trading assessment was carried out at our Guangzhou facility by Intertek, commissioned through Alibaba.com's verified supplier program — report 481351002_P+T, issued 2026-01-15, valid to 2027-01-15. Report authenticity can be checked at intertek.com.cn/ASV.
What the auditors verified on the floor: 1,000+ models across five product categories, a documented production flow (disassembly → cleaning → component repair → testing → assembly → packing) with written work instructions, finished-product inspection on every unit, a closed-loop corrective-action system, and lot-level traceability from finished goods back to incoming material.
Trading capability was verified in the same audit: MOQ from 1 piece, fastest lead time of 1 day, a 12-month quality guarantee across all product categories, and export handling via Guangzhou Port on FOB / CIF / EXW / CFR terms.
