The tools for working on the 915
The Porsche 915 transmission requires special tools to disassemble. This is an overview of all the Special Tools you will need to be able to work on the Porsche 915 transmission.
P37
The first Porsche special tool you will need is the P37 tool. However this tool is optional, it is possible to use an impact wrench aswell. Just make sure to spray the bolts to loosen them a bit.
P355
The second special tool you will need (this tool is quite difficult to find) is the P355a tool. This tool is going to hold the pinion shaft so you can turn the bolt holding all the gears together. There are some workarounds if you dont find these tools. One can use an old fifth gear as this has the same dimensions as the P355a tool. An other option is to fasten the input shaft from the other side by using a clutch disk as this has the same teeth dimensions as the P256 tool.
P256
