2guard,
48 745 0205 I dont know about the leading 48 but the 745 0205 is a proper S/N for a 75 transmission. 745 0205 7 = Transmission for 6-cylinder. 4 = 4-speed, 915/48 (RoW) or 915/45 (USA). 5 = Model year 1975. 0205 = Consecutive serial number. 915/45 USA) is geared: 1st = 11:35 2nd = 20:32 3rd = 25:27 4th = 28:23 R&P = 8:31 and 915/48 (RoW) is geared: 1st = 11:35 2nd = 20:32 3rd = 25:26 4th = 29:21 R&P = 7:31 You will find the Type Number (915/xx) next to the transmission number. Best, Grady
