Frequently Asked Questions

Sun Eng Hup provides comprehensive auto transmission solutions for European, Japanese, and Korean vehicles. Our services include:

  • Computerized transmission diagnostic scanning and fault code reading
  • Mechatronic unit and valve body testing, solenoid replacement, and reconditioning
  • Torque converter overhaul and rebuilding
  • Complete gearbox overhauls, remanufacturing, and rebuilds
  • Supply and installation of low-mileage tested used (half-cut) and reconditioned transmission units
  • Transmission fluid (ATF/CVT/DSG) and integrated filter service replacements

All reconditioned and tested replacement gearboxes supplied by Sun Eng Hup come with warranty protection. Warranty periods typically range from 1 to 6 months, depending on the specific vehicle make, gearbox model, and application type. Every unit undergoes rigorous hydraulic pressure, electronic, and bench testing prior to installation or shipment to ensure seamless shifting and reliability.

Rebuilt Transmission: The original gearbox is disassembled to inspect internal wear, replacing only the specific broken or worn components (such as clutch plates, seals, or solenoids) while retaining intact existing parts.

Remanufactured Transmission: The unit is completely restored to factory standards. All wear-and-tear items are replaced with fresh high-grade components, the mechatronic/valve body is recalibrated, and the full assembly is load-tested to deliver performance equivalent to a brand-new unit.

Used (Tested Half-Cut) Transmission: An original factory gearbox harvested directly from low-mileage donor vehicles (direct-imported from Japan or Europe). It offers an economical direct replacement option that has been functionally tested for operation.

Yes. Sun Eng Hup is both a leading transmission parts supplier and a full-service repair facility. You can purchase complete gearbox assemblies directly from our Segambut warehouse for wholesale delivery, or have our experienced technical team perform complete gearbox removal, installation, coding, and adaptation services at our Segambut workshop in Kuala Lumpur.

Before recommending any repair or replacement, our specialists conduct a thorough multi-point diagnostic inspection:

  • Computerized TCM/ECU Scan: Reading real-time transmission fault codes, temperature sensors, and clutch adaptation values.
  • Fluid Quality & Level Inspection: Checking ATF/CVT fluid levels and analyzing for contamination, burnt residue, or metal particles.
  • Hydraulic & Electrical Testing: Inspecting solenoid resistance, pressure switches, and mechatronic control boards.
  • Physical & Road Testing: Assessing gear engagement times, shift smoothness, torque transfer, and driveability symptoms.

We specialize in automatic, manual, CVT, and dual-clutch (DSG/DCT) gearboxes across leading European and Asian brands, including:

  • BMW (ZF 6-speed, 8-speed, GM, and DCT units)
  • Mercedes-Benz (5G-Tronic, 7G-Tronic, 9G-Tronic, and DCT units)
