With so many 914 engine and transmission swaps and combinations, I was wondering if any 914's with automatic transmissions exist. Anyone know of one out there?

I came across this site while searching for Celette frame machine info for a non Porsche project. In the 90's got my 914 and I was on Renn list when John D started it from the left overs of an e mailing list. Maybe Porsche list?

In the early days, you would have your e mail address added to a list on a server, other users would send an e mail to the server then it would rebroadcast to all users either in real time or once daily. One could also request a list of subjects or a certain days mailings.

Anyway. . . . In the early 80's I actually drove a Sporto a short distance ( parking lot to shop ), I'm not sure if it was a 6 because there were 2 other customer cars that were a 4. Given the posts here, I'd say it was a 6. One of the mechanics thought I'd be confused by no clutch pedal but they were unaware that I was familiar with the VW sporto so there was no drama. I also knew arcane things like that a SAAB 99 / 900 had a hood that popped up in the front / slid forward then tilted forward and the ignition key was in the floor.

The VW sporto was 3 speed with a torque converter, the 914 has 4. Power flow was engine - torque converter - dry plate clutch - "standard" trans gearbox so this is a semi auto where one has to shift but not manually clutch.

The shift lever had a spring and electrical contacts at the base. When you pulled on the shifter the contacts made, actuated a vacuum valve that opened the clutch ( like pressing the clutch pedal ) , as you continued to move the shifter, the proper gear was selected. Let go of the shifter, vacuum valve closes ( with a short delay ) and the shift is complete.

The torque converter allows the car to remain in gear while not moving so you could start out in top gear if you wanted to. This was very slow and could overheat the converter fluid. ( VW had an over temp light, Porsche likely did also )

There is a torque converter charging pump run by a second stage on the Type I VW oil pump that draws ATF from a 911 dry sump looking tank. It would be possible to add a belt driven charge pump it you really wanted some sort of conversion.

The most direct route to a 914 auto might be a 73 ish to 81 ish Type 2 VW Bus conventional full auto as these came attached to the type 4 / 914 motor. However. . . The trans is facing the wrong direction. It _might_ be possible to flip the ring gear but most likely the trans would need to be flipped with lots of custom stuff. I'd probable try to flip the final drive housing then report / add external lines to the transmission portion. ( the final drive and trans were 2 separate units. )
