Not sure which one your car has?
Provide the VIN when booking an appointment, and before you arrive we will check which transmission you have in your car and if we repair it.
Below are the codes from this list, ordered from the most common. These are the ones to look for in the registration document or on the transmission plate when you order parts.
EAT6 and EAT8 are showroom names, not transmission codes. Both names hide an Aisin automatic with a torque converter, but in several sizes, matched to the engine torque. Under EAT6 there is sometimes a lighter version (on the plate AT6 III, u Aisina AWF6F25) or the stronger one, fitted to 2.0 diesels (AM6 III, AWF6F45). Similar for EAT8: ATN8 or AMN8.
Dlatego we do not add a single code to the EAT name. The same name in two cars can mean two different transmissions, and when you order parts a mistake costs money. What decides is the plate on the transmission or the VIN number, which we check before you arrive.
This list includes: AWF6F25, AWF6F25(TF-72SC), AWF8G30, AWF8G30H, AWF8G45, EAT6, EAT8. Your registration document says “EAT6” but the list shows a code? It may be the same car. Send us the VIN, and we will tell you which transmission is in it.
The list above shows the code a mechanic reads: the code from the plate, the parts catalogue number or the design symbol. In a search engine people type something else: the transmission model name or the showroom name. These describe the same transmission. Below are the ones that appear in this list, together with the clutch type, because that decides how the repair runs and what it costs.
| Transmission model | Trade name | Gears | Clutch | Torque | Layout |
|---|---|---|---|---|---|
| 6T40 | Hydra-Matic | 6 | torque converter | 240-280 Nm | transverse |
| AWF6F25 | EAT6, AT6, AWF6F25 | 6 | torque converter | transverse | |
| AWF6F25(TF-72SC) | 6 | torque converter | transverse | ||
| AWF8G30 | EAT8, ATN8, AQ300, 09S | 8 | torque converter | transverse | |
| AWF8G45 | EAT8, AMN8, Geartronic | 8 | torque converter | transverse | |
| C635 DDCT | TCT | 6 | dry clutches | transverse | |
| EAT8 | EAT8, Efficient Automatic Transmission 8 | - | torque converter | transverse | |
| TF-80SC | AM6, AF40-6, Geartronic | 6 | torque converter | transverse | |
| e-DCT6 | e-DCT, e-DCS6, e-DCT6 | 6 | wet clutches | 350 Nm | transverse |
Maximum torque is the highest torque the transmission can safely handle without risk of damage. It is the factory figure for the transmission model, not for one particular car. Some codes from the plate have no publicly confirmed model assignment, and those stay in the table without a second name. The VIN number is what finally decides, which we check before you arrive.

Read →C3/C4 clutch drums and common faults. How to drive so it lasts longer.
Read →Describe the symptoms: at what speed they appear, with the engine cold or warm, whether there is a jolt when shifting, a delay after engaging a gear, or a message on the dashboard. Add the model year, the engine and the VIN. We will write back with what that suggests and which check makes sense. Whether we take the repair is decided by the diagnostic check.
