How to order Volvo I-Shift parts from Volgen Power

Three steps, no account required.

  1. Send the OEM number printed on the part or on the gearbox identification plate (AT2412 / AT2612 / ATO2612 / SPO2812 series).
  2. We confirm the fitment against the compatible model list and the supersession chain shown above.
  3. Receive a quotation with wholesale pricing, packing and lead time, usually within one working day.

Frequently asked questions

Are these parts interchangeable with Gen F (AT2612F) gearboxes?
Each row shows the applicable supersession numbers. Where a Gen F number exists it is listed in the Interchange column — confirm your gearbox identification plate before ordering.
Do you supply both C/D generation and F generation countershaft brake components?
Yes. C/D-line and F-line kits are separate part numbers and appear as separate rows; they are not interchangeable.
What information do you need for an accurate quotation?
The OEM number, the gearbox model code and the quantity. A photo of the identification plate is the fastest route.
