Available Services

This hub is reserved for upcoming services. Contact us if you need this work — we can provide a quote based on your specific module and part number.

Not Sure Which Service to Choose?

If you are unsure which option matches your Volvo module, the safest path is to email or text us photos before ordering: full label of the original module (the one you want serviced), full label of the donor module if you already have one, the part number, hardware revision, and software/calibration sticker, and a photo of the connector pinout if visible. We will confirm whether the service is supported for your specific part number and hardware revision before you order and ship.

Compatibility Warning

TCM service requires correct identification of the transmission family (TF-80SC, TF-81SC, Powershift, etc.) and the TCU hardware revision.

What to Ship

Your original Volvo module (the failed/locked unit), clearly marked “ORIGINAL”
If applicable: a donor module, clearly marked “DONOR” — same part number family and hardware revision as the original
Your order receipt printed, or order number written on a slip in the box
Your return shipping address
Ship to the address shown on your order receipt at checkout (we operate from 2 locations and route based on tool availability and turnaround)
