New PN021 Update: Reuse Second-Hand Aisin AXN8 (EAT8) TCUs in Peugeot and Other Stellantis Vehicles

Replace Faulty Transmission Control Units Without the Original Module

ABRITES introduces a new addition to the PN021 – Instrument Cluster Data Manager (IC, BSI, BCCM, VSM, TCU), allowing automotive professionals to reuse donor AXN8 (EAT8) transmission control units in Peugeot and other Stellantis vehicles manufactured from 2018 onwards.

GET LICENSE

The procedure requires only the current vehicle PIN code. There is no need for the original transmission control unit, making it possible to complete repairs even when the original module is damaged, missing, or completely unusable.
This gives independent workshops a practical and cost-effective way to repair vehicles using second-hand transmission modules from salvage cars.

Adapt Second-hand TCUs by OBD

For supported software versions, donor AXN8 (EAT8) transmission control units can be personalized directly via OBDII, allowing the entire replacement procedure to be completed quickly without opening the module.
This is the fastest way to replace a faulty TCU and get the vehicle back on the road.
If the installed software version is not currently supported by OBD, the procedure can still be completed on the bench. Read the donor TCU using the ABRITES RH850/V850 Programmer, then adapt it using the vehicle PIN code.
This flexible approach allows workshops to successfully complete many more transmission module replacement jobs regardless of the software version installed in the donor unit.

Why This Matters

Finding a new AXN8 (EAT8) transmission control unit can be expensive and often involves long delivery times. Used modules from donor vehicles, on the other hand, are widely available and significantly more affordable.
With the latest PN021 update, workshops can confidently install second-hand TCUs, reduce repair costs for their customers, and minimize vehicle downtime.

Key Benefits

  • Reuse donor AXN8 (EAT8) transmission control units
  • Original TCU not required
  • Adaptation using only the vehicle PIN code
  • OBDII procedure for supported software versions
  • Bench procedure using the RH850/V850 Programmer for unsupported software versions
  • Lower repair costs and reduced vehicle downtime
  • Ideal for independent garages and transmission specialists

Supported Vehicles

Compatible with Peugeot and other Stellantis vehicles equipped with the Aisin AXN8 (EAT8) 8-speed automatic transmission, including many of the most popular models produced from 2018 onwards.
