⚠️ Warranty Terms for This Repair

• Our 12-month warranty on this repair is conditional on a full transmission oil and filter change being carried out at the time of refitting.
• Please keep proof of this — a paid invoice from a garage or workshop — as this will be requested if you ever need to make a warranty claim.
• This is a transmission component, and correctly completing the fit requires the correct basic settings, adaptations and teach-in procedure for your specific gearbox to be carried out afterwards for it to operate correctly.
• Many owners with the right diagnostic equipment and experience fit these themselves — that's completely fine. If you're doing the oil/filter change yourself rather than at a garage, keep your own dated records (receipts for the oil/filter, and confirmation the adaptations were completed) as equivalent proof for a claim.
