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.

Codes

  • TF-80SC 2 models
  • DA1-C635 2 models
  • 8HP 50 2 models
  • 8HP 75 2 models

Trade names

What the transmission names mean in Alfa Romeo

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
8HP50 Steptronic, ZF 8HP 8 torque converter 500 Nm longitudinal
8HP75 Steptronic, ZF 8HP 8 torque converter 740 Nm longitudinal
C635 DDCT TCT 6 dry clutches transverse
TF-80SC AM6, AF40-6, Geartronic 6 torque converter 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.

Gearbox trouble in your Alfa Romeo? Write to us

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.

Which code to look for on the registration document
