Andrew, that is an early 66 model 902/1 5-speed for either 4 or 6 cylinder cars.
For 66, Porsche used these transmissions in both models without separate serial number ranges.

I seen First 2 means 6 cilinders.
Maybe late 1965?

No, for 902/1, Porsche said 65 model transmissions ended 26 July 65 at 221721, so 222469 is a 66 model transmission.
For 66 model 902/1 transmissions, "first 2" can be either 4 or 6 cylinder.

I have 222414 (car was ready on 08-25-1965), so yours was right behind mine.

902/0 and 902/1 were four speed and five speed versions technically intended for the 912, but were used interchangeably with the 911. The 901/0 and 901/1 were technically intended for the 911. There seem to be a lot fewer 901s than 902s, and that could be because there were a lot more 912s than 911s.

The gearing on both 902 and 901 above were the same, but there were other variants in very limited numbers.

The type number is stamped on the bottom rib next to the serial number. The number posted above is the casting part number for the case. It is not listed as a purchasable part. The serial number gets you where you want to be, though.

Bottom line is these are not rare, and are not "special". They are, however, good transmissions. Good used cores are probably in the $500 to $800 range.

Just to clarify the dates from the Porsche document...
8.9.65 means 8 September 65.
7.12.65 means 7 December 65.
