Is there some data out there on the 901 tranny differences between the years it was manuafactured?

Do all 901's have the same shift pattern?

A table of the available gear ratios:

Some 901 boxes from 911s and 912s were four-speeds. Not many, though. And of course there were the "Sportomatic" transmissions, which were either three-speed or four-speed, I forget which. But those are a very different animal indeed.

From my readings, I think 3.2 is where you run into enough problems with the 901 to make a 915 conversion a better idea. The 3.0 engines seem to do OK with 901s that are in good shape, but from the sound of it the ones hooked up to 3.2 motors start having real problems...
