Exactly. I just did some further research and found the following posted by Peter Zimmerman:
"The 915/06 transmission was used in the '74 911, 911S and Carrera, and the 1975 Carrera. It's a 5-speed with the following ratios:
1 - 11:35
2 - 18:33
3 - 23:29
4 - 27:25
5 - 29:21
...and was fitted with the 7:31 ring & pinion."
The Second digit being a 3 differentiates it from being a regular 911 trans. As far as the year, I have send Peter a message to clarify, but I believe the 75 Carrera's still had the 74 trans. I'll update this once I get confirmation. The VIN of my Carrera is 9115400108 so it was a pretty early build.
