Is a '902/0' gearbox 4 or 5 speed?

[013znk]

Hey all: I'm new to the forum, and am starting out by asking what is probably a ridiculously easy question for most of you, that is, I'm trying to figure out what kind of gearbox I've got for my '67 912, i.e. is it a 4 or 5 speed?

The box is stamped with the type designation: 902/0, and the serial number is 163781.

Any help would be kindly appreciated, and perhaps some guidance to where I could find a chart online with gearbox type, serial number designation? Thanks in advance.

Here's one of the charts that W. Hall kindly posted which lists some of the gearboxes. The 902/0 also applies to the 912.

Stock, the 902/0 is a 4-speed with 4th gear the same ratio as 5th on the 902/1 5-speed

Here's a link to the 912 Registry gearbox page with various 912 boxes and serial number ranges; if anyone has info for the others boxes like the 902/06, etc please comment:

Where do you look on the transmission to see what you have? I know my car was upgraded to a five speed.

Thanks all, for you quick replies. Mystery solved, 4-speed.
