TS11 TS12 Clutch Input Drum Assembly

The TS11 TS12 Clutch Input Drum Assembly is an internal transmission component used in selected CVT180 continuously variable transmission applications. Current transmission-parts listings identify TS11 and TS12 clutch/input drum assemblies for Roewe and MG CVT180 gearboxes, while dedicated TS11 product pages also describe the part as a clutch drum, input drum or automatic transmission input shaft assembly. The component sits in the transmission input and clutch section, where it helps transfer engine torque into the internal CVT drive system.

This product is intended for professional transmission workshops, CVT rebuilders, automotive parts distributors and wholesalers. Because TS11 and TS12 parts can be listed under different market descriptions, customers should compare the original drum shape, shaft design, spline profile and transmission code before ordering. We do not recommend selecting the part only by vehicle model.

TS11 TS12 Clutch Input Drum Assembly Function

The TS11 TS12 Clutch Input Drum Assembly combines the functions of an input-side drum and shaft-based clutch support component. In specialist market listings, TS11 units are commonly described as “Input Drum Assembly,” “Input Shaft Transmission Input Drum,” or “Forward Gear Clutch Assembly.” These names refer to the same general repair area but may describe slightly different package configurations depending on the supplier.

During operation, torque enters the transmission through the input section and is transferred through the clutch and drum assembly into the CVT drivetrain. The drum and shaft must maintain correct alignment, spline engagement and rotational stability. Wear, deformation or damage in this area can affect power transfer and may contribute to abnormal noise, poor engagement or internal transmission failure.

Because the assembly is a hard transmission part, it is normally replaced during internal gearbox repair rather than routine maintenance.

TS11 and TS12 CVT180 Identification

Current public transmission-parts sources clearly identify TS11 as part of the CVT180 family and list input drum or input shaft assemblies for Roewe and MG applications. Some market listings also group TS11 and TS12 together as CVT180 gearbox clutch/input drum assemblies.

The strongest publicly available support is for TS11. Dedicated suppliers list CVT180 TS11 Clutch Drum and TS11 CVT Auto Transmission Clutch Input Shaft, while other current catalog listings describe the product as an input drum for Roewe CVT180. TS12 is also sold together with TS11 in current transmission-parts marketplace listings, but I could not verify a reliable manufacturer document proving that every TS11 and TS12 version uses exactly the same physical drum.

For that reason, the safest product-page wording is “for TS11 / TS12 CVT180 applications” rather than claiming universal interchangeability.

Roewe and MG CVT180 Applications

The TS11 CVT180 clutch/input drum is commonly associated in market listings with selected Roewe and MG applications. Current supplier pages mention vehicles such as Roewe i5, Roewe i6, RX3, MG5 and MG ZS, depending on production year and transmission configuration.

Vehicle application should be treated as supporting information only. The same vehicle model can use different transmissions across markets, engines and production periods. Transmission code and physical comparison remain the preferred matching methods.

When ordering the TS11 TS12 Clutch Input Drum Assembly, customers can provide the transmission code, original product photos, shaft and spline photos, drum dimensions, vehicle information and required quantity. If the original transmission has previously been rebuilt, direct physical comparison is especially important.

Input Drum and Shaft Inspection

During transmission rebuilding, technicians should inspect the input drum and related internal components for spline wear, cracks, distortion, bearing damage and abnormal contact marks. The input shaft should rotate smoothly and should not show excessive wear in the bearing or sealing areas.

Related components that should also be checked include bearings, clutch friction components, seals, pulley assemblies, oil pump parts and transmission fluid condition. Metal debris inside the transmission can indicate broader internal damage and should be investigated before the replacement assembly is installed.

Clean assembly procedures and correct transmission fluid should be used during reassembly.
