Remanufactured C725 7-Speed Dry Dual Clutch Transmission Assembly 1310003CAC0100 for Trumpchi GA6 1.8T DCT Complete Gearbox

This remanufactured C725 seven-speed dry dual clutch transmission assembly fits Trumpchi GA6 equipped with 1.8T turbo engine.

Official OE number: 1310003CAC0100.

C725 dry DCT is widely matched to Trumpchi GA6 sedan. Common serious faults include clutch ablation, shifting shudder, gear slipping, abnormal internal noise, failure to engage gears and housing damage. These failures cannot be solved simply by replacing valve body or separate clutch parts.

Our remanufactured whole gearbox undergoes full disassembly inspection, renewal of damaged components and continuous bench running test, ready for direct vehicle replacement.

1. Housing Inspection: Recovered aluminum housing is inspected for cracks, deformation and oil leakage; defective housings are eliminated directly.
2. Complete Disassembly & Deep Cleaning: Take apart all internal assemblies. High-pressure circulation cleaning removes oil sludge and metal debris inside oil passages.
3. Consumables Renewal: Replace dual clutch friction plates, bearings, oil seals, synchronizers and aging rubber parts with qualified new spare parts.
4. Clearance Calibration: Adjust clutch working clearance and gear meshing clearance strictly following factory standard parameters.
5. Bench Running Test: Simulate forward/reverse shifting and load operation to check abnormal noise, shudder and oil leakage.
6. Anti-rust Treatment & Export Packing: Anti-rust film + customized EPE foam + neutral export carton or plywood case to prevent damage during long sea and land transportation.
