Trying to decipher a tranny number.
Anybody know the difference between a 771xxxx and a 711xxxx?
What does the "7" mean?
From here:
901 Series Porsche Transmission
Shows:
901, 902, 905 and 911 types
AAA/AA BB CDE NNNN
A = Type (i.e. 06 = 901/06)
B = Differential Designation, 12 = ZF LSD, missing = no LSD
C = Application, 5 = 4 cylinder engine, 7 = 6 cylinder engine
D = ?
E = ?
N = Sequential Serial Number (i.e. 0001, 0002, etc.). Some models did not start with serial number "1"
Thanks!
