Unicorn automatic transmission

Aside from the flip bit, only one that comes to mind is Porsche 928 which might do? Might be a bit light on the torque figure though.

Sadly not that small..

I'm back on the gas turbine

It will do. Max rpm seen by the box 5,500/6,000 rpm.

Do the early Audi Ax ones have no electronics? For me that means you need to go back into the 1980’s/early 90’s? In fact that’s a thought - Audi 80/90 turbo (non-Quattro)?

One does think of the infamous Renault 25 transaxle as fitted to many a GT40 replica but I wonder if there are any auto ones left?

Sadly it was the Variomatic and the CVT belts did not like torque

Or strong enough?

I can run the gas turbine without a box as the free turbine acts a torque converter but it's like driving a single speed milk float. I may just have to go for a manual and be prepared to replace the clutch on a regular basis but as it's only likely to see a few shows and track/hillclimbs a handful of time per year it shouldn't be a big problem.

What about a slider clutch and manual gearbox? I don't know of any autos that fit the bill. A guy brings flipped/2WD converted Subaru gearboxes to us for cleaning I'll ask if he knows any autos that can be done.

Another thought - is the Centreline of the output shaft higher up than a conventional engine (like a Wankel)? If so could you a conventional auto then a 4x4 transfer box and diff to get the power to the wheels?

Surely come with plenty-o-electronics?
