Reprogramming can only be accomplished by an authorized Allison Transmission distributor. You must provide the
transmission serial number of the transmission being installed to ensure correct reprogramming. If at a later time, an
earlier version transmission is installed in a WTEC II equipped vehicle, WTEC II TEPSS will require reprogramming
again.
