Manual Transmission Identification


A transmission serial number is stamped on each transmission case or to a plate which is welded to the case. Location of the ID number will vary with the transmission manufacturer. With the Borg Warner T-5 transmission or New Venture Gear 1500/3500, locate the transmission ID number on the front right of the housing.
