Transmission Assembly Categories
A transmission assembly is the complete transmission unit, as distinct from a single part inside it. This page is the category map for the whole site: it names the four assembly categories, the three supply forms and the parts categories that sit alongside them, and it explains how a buyer moves from a category to a quotation. No individual assembly is sold on this page, and no specification is published for any category.
The four assembly categories
AT assemblies are traditional automatic transmissions. CVT assemblies are continuously variable transmissions. DCT assemblies are dual-clutch transmissions. Transfer case assemblies distribute drive in four-wheel-drive applications. Those four sentences are the whole of the category definition offered here, and they are enough for a buyer to identify which category an application calls for. Anything beyond that, such as gear sets, clutch arrangements or control strategies, is specialist detail that belongs to a confirmed unit, not to a category map.
Keeping the map at category level is a deliberate choice. A site that dressed up category names with invented ratios, dimensions or vehicle lists would look more detailed while being less trustworthy, because a buyer could not tell which figures described a real unit and which were filler. This page therefore gives the buyer the structure of the range and directs detailed questions to the inquiry, where they can be answered for a named unit.
Supply forms and parts categories
The three supply forms in company materials are new assemblies and parts, remanufactured assemblies and parts, and used transmissions with used cores. New supply is the focus of the general pages, remanufactured supply is described here only at category level, and used supply is mentioned here only to complete the picture. A buyer who is weighing new against remanufactured supply should state the application and the budget constraint in the inquiry, so that the reply can address the comparison for that case rather than in the abstract.
Parts categories listed in company materials include valve bodies and mechatronic units, chains and pulley sets, solenoid kits, clutch kits, sealing kits, friction plates, steel plates, filters, thrust washers, rubber parts, differentials, oil pumps, pistons, torque converters, sensors and electronic controls. The parts categories page gives the fuller list with its groupings. On this page they serve one purpose: to show that an assembly inquiry can also cover the supporting parts a workshop or distributor needs, without turning this category map into a parts catalogue.
From category to quotation
The path from this page to a quotation has four steps. First, identify the assembly category. Second, choose the supply form. Third, state the quantity and the target date. Fourth, describe any packing, documentation or after-sales requirement that affects the order. Share your quantity and target date to get MOQ and lead time for your order. A quotation prepared from those four facts will be specific, checkable and comparable, which is more useful than a general price that no one can act on.
Warranty is stated as at least 1 year, following company materials, and certificates are available upon request. Both statements are intentionally general on a category page: the warranty and certificate position for a specific unit is confirmed when that unit is quoted. Buyers who need either point settled before proceeding should raise it in the first inquiry message, so that it is answered alongside price and timing rather than discovered after an order is placed.

Brand names appear on this site exactly as used in company materials: Meishun, MESUN and TRANSMESUN. No single spelling has been imposed over the others.
