P355a

The 901/914 transmission uses a 1st/rev shift sleeve guide similar to the 5th/rev guide on a 915 transmission except the shaft is smaller. The splines fit the 915 mainshaft just like the P355a....

I forgot to say you cannot measure a current leak with a mulitimeter. If you find a leak it will peg the meter and you should immediately disconnect or you might burn up your meter. You are looking...

I had a similar problem many years ago with a 356 which was due to a current leak on one of the circuits. With a 1971, there should be no current flowing through any circuit with the exception of the...

I just reuse the pinion shaft bolts unless they show corrosion. I have plenty of used ones. Same for the axle flange bolts.

The mag case was introduced in the 911 in the middle of the 1969 model year. Way back when, I had a 1969 911S that had an aluminum case trans but late cases are mag.

Simplified Differential

You cannot do this conversion on a 1966-69 aluminum case transmission. The differential housing is too small to accept the later parts.

Are you talking about the oil leak collector that's pressed on the wheel hub? If so, I have one I removed from a bent hub.

The switch should be for the rear window heater. Emergency flasher had a warning triangle symbol. Switch and axles would be the same as 911 for their model year.

Try a different coil.

I owned and worked on 911s back then and am almost certain the parts were painted matt black. Of course, then we didn't really pay much attention to details like that.

I've done this sort of thing several times for 901/914 transmissions. For a 1972 915, you would need to use the 2nd gear dog teeth and anchor block; etc like those used in your current 2nd gear.

If you have a 902/02 check the axle flange bolts for wear on the projections on the ends. They wear out after about 100K miles. Disaster if they break off. I've got pictures if you want to see.

Check your cam timing.

Peiseler withdrew from the auto repair tool market several years ago and no longer supply repair parts for the tools they made earlier. They are still in business and offer tools for CDC machining.

Hex Plug

The hex plug was used for Porsche transmissions from the 1950s until it was dropped in the 1980s. Just buy one on the internet.
