Transmission identify/info Options

My 1974 914 I bought did not come with an engine or transmission. I bought this off craigslist titled as '914 transmission for sale'

Guy didnt know anything about it. Said it was a 5 speed that was pulled from a running 914 and shifted fine, no known issues, blah blah...

Oh he said this is a tail shift?

I only found two numbers on it. Cant seem to locate a manual for specifications.

I need to get a clutch for it, replace the seals since its out, replace the oil, etc.

Are there manuals for this?? With these numbers is there a way to reference what year/type etc?

Also, what is the little two prong switch? backup/reverse switch or vacuum sensor?

914.301.301.03
914.301.101.00

Im slightly confused about the numbering of the transmissions.
Did a Porsche 914 car come with a 901 trans, a 914 trans, or either depending on year?

This first number 914. designate this is a 914 trans? or for a 914 car?

All 914 clutches are functionally the same. The only major difference would be in the disc; 914/4s had a 4 spring disc, 911 to '69 and 914/6 had a 6 spring disc. The 4 and 6 flywheels were made of cast iron, the 911s (until 1969) were made of steel. The seals were also the same for all 914 transaxles. As DD said above, this is a tail shift. I don't think there's an adapter firewall bushing made to backdate the linkage in your car, so there's a big stumbling block right there. It is possible, and quite common, to update the transaxle to the later configuration. It's something you may be able to do yourself once you've learned the essential procedures and pitfalls. All the appropriate seals and gaskets for either version come in the gasket set.
