Automatic Transmission Assembly
An automatic transmission assembly is a complete transmission unit, supplied as a whole rather than as a collection of loose parts. This page describes complete assemblies at category level, explains how they differ from parts orders, and sets out the inquiry steps that turn a category choice into a quotation. It is a companion to the transmission assembly category map, with the emphasis here on completeness: what is included when a buyer orders an assembly, and what must still be confirmed.
Complete assemblies, not loose parts
Ordering a complete assembly means ordering a unit that has been assembled and checked as a unit, rather than ordering the parts and assembling them elsewhere. That distinction is the reason this page exists separately from the parts categories page. A buyer who needs a complete unit for a replacement or a new build should order an assembly; a buyer who needs to repair or rebuild an existing unit should look at parts categories and specialist repair material instead. Confusing the two leads to orders that cannot be used as intended, however accurately they are priced.
The complete assembly categories are AT, CVT, DCT and transfer case assemblies. Each is described at category level only, with no ratios, dimensions, torque figures or vehicle applications published here. Those figures belong to a specific unit, and a page that attached them to a category would be inventing a specification for units it has not identified. A buyer who needs a figure for a real application should name the category and the intended use in the inquiry, where the correct unit can be identified.
Supply forms for complete assemblies
Complete assemblies are supplied in the three forms named in company materials: new, remanufactured and used. New assemblies are the focus of the general pages. Remanufactured assemblies are described here only at category level, and used assemblies are mentioned here to complete the picture. The form matters for a complete assembly more than for a single part, because condition affects warranty, testing and after-sales support, and a buyer who does not state the form in the inquiry may receive a quotation for a different form from the one intended.
Quality checking for finished assemblies is described in company materials as intelligent testing equipment for initial inspection together with vehicle testing. This page states that approach generally and does not publish test results or thresholds. A buyer who needs test documentation for a specific assembly order should request it in the inquiry, so that the documentation supplied corresponds to the units actually delivered.
From assembly category to order
The inquiry path for a complete assembly has four steps: name the category, choose the supply form, state the quantity and target date, and describe packing, documentation and after-sales needs. Share your quantity and target date to get MOQ and lead time for your order. Those four steps produce a quotation that can be checked, compared and acted on. A quotation missing any of them is a general indication, not an order, and should be treated as such until the missing facts are supplied.
Warranty is stated as at least 1 year, following company materials, and certificates are available upon request. Both should be asked about for the specific unit when requesting a quotation. Buyers who need warranty or certificate wording for a customer or an authority should include that requirement in the first inquiry, so that the quotation answers it in the same document as price and timing.
