I imagine either of the reputable builders (Beck/Special Edition and Vintage Motorcars) would be able to help you out, particularly if you went with a water-cooled drivetrain.

I doubt Vintage Motorcars would entertain this idea. I say this based on the fact that Greg has tried to streamline his business and is no longer taking on Suby builds. These one off style builds derail his production.

Yes an automatic from a Fastback or Squarebqck from 1968 to 70 would work well. They were made by Borg Warner.  They are scarce and expensive.  A shop out in Socal in the LA area services them.

Next would be a Subaru trans. Coupled with a Subaru motor, you would have a superior set-up. Plus all the inputs to and from the ECU would be available and working. This would make a really nice daily driver.........Bruce

I don't remember anybody ever producing anything to beef up the autostick, and as @LI-Rick mentioned, they didn't last under much power at all.  These days, if you can find an autostick, all people want them for is the 2.25 2nd gear, and only some of them have it.

And I remember in the late '70's and into the '80's the Type 3 auto being used in drag racing.  I couldn't tell you who figured out/did the modifications to make them live with big power, but being designed (and built?) by Borg Warner, I wasn't surprised they could be re-worked.

I've done it in our coupe, 4EAT Subaru, not a big deal, and we are watching the reversed 4EAT development and sorting of the teething issues to see what happens for rear engine applications.   As of right now there have been several reversed Suby failures that have me leery of them, BUT they have also been in heavily modded Busses ant 3-4x the weight of a Speedster.  

I have not found anyone confident in rebuilding the T3 autos, including Rancho, siting no parts availability at all.  There is a shop that advertises they rebuild the 090 aircooled Bus auto, so in theory that its a possibility but they do not supply boxes, just rebuild, and I'm certain there'd be a heavy amount of fab work from chassis mods to make it fit, down to custom axles, vacuum system, etc...

The failures you speak about in the suby are they all automatics ?  

I know IM had used bus trannies in a few cars, but hey what do I know.

Yes, the early Subaru manuals had their share of failures too, and they still have a few issues "here and there", but have largely been sorted out.  There is a lot of debate about the ring gear hardness, but we've found that in our light weight cars it has been a non-issue, and it seems to be isolated to either super high HP builds, off road, and heavy busses.  

The failures I was speaking of above are in the automatics and the 2 different ways they have been designed.  Neither of them is perfected yet and I'm juts not confident in them enough to "pull the trigger" but wait with baited breath...

@Rando

There was a SOC member @Nolan-Tennessee who had a beautiful SAS (Specialty Auto Sport) Cabriolet with an automatic. He eventually sold due to health issues. He may respond to this notice with more details. NOTE: SAS has a rather notorious reputation (may even be out of business) that you can review through a 'Search' on the tool bar above.

There was also another SOC member (a long time ago) who had a Speedster with an automatic (VW I assume). I can't remember his name but he also had a disability that prevented his ability to drive a manual transmission. IIRC he had an 1835cc motor and had that car for quite a while without transmission issues. Some other SOC members with better memory may chime in.

So, yes, there have been Speedster replicas built with automatic transmissions, but they are a rare breed.
