This unit normally fails activating the Transmission visit workshop message on the dash or Transmission consult workshop message might appear, the most common failing part numbers are A 1695451032 and A 0034462410. All repairs comes with a 12 month unlimited km warranty* . Most units are re-manufactured within 24 hours, this includes re-engineering of all the original speed sensors circuitry to prevent repeat failure. We also include a before and after test on our purpose built speed sensor simulator to ensure your unit is re-manufactured to the highest standard. As we re-manufacture your unit, there is no need for the additional cost of SCN coding or adaptation.
