Your transmission was built using the same casting as for the 1970-71 911 and the part number on the casting should be 911xxxxx. The casting differences Porsche made for the 911 are more reinforcing ribs inside the bellhousing, the tab on the outside of the bellhousing used to hold the 911 pull clutch cable and the serial number pad on the bottom.
The machining differences between the cases used for the 911 and 914/6 were the different locations for the vent on the top of the case and the location for clutch fork pivot inside the bellhousing. For the cases used for 911s, a steel reinforcement strip was installed inside the differential carrier to take the force of the pull clutch. I have seen two 914/4 transmissions built with 911 cases. Probably done to use extra castings that were not needed for 911 production. |
