Going by 1989 technology, an auto engine's ECU should work with a
manual trans; it might be set for slightly lower torque output than a
manual engine, but the shifting software would merely be redundant.
Everything necessary to run the engine would be there.
Of course a manual ECU won't work with an auto, as it would lack
electronics/software for shifting.

How on Earth did you manage to reverse the differential? I looked
into both Audi & Subaru transmissions before forking-out for a
Porsche trans... it wasn't "doable" (apparently). You altered the
gearbox shafts to do it?

Expense. And most T3 owners, at least those on the list, are looking
for cheap options.

Blah. Why an auto? Shifts when you don't want them, no shift when you
want one, trans insisting on upshifts short of the redline no matter
what you do, people saying that the tiptronic levers are behind the
wheel (when in fact they're in front of it)... and (of prime
importance for a European vehicle) not towable.

In addition to the trans, the rear diff would need major surgery to
flip the diff over...

Same for the Audi rear diff. EXPENSIVE.
Hmmm... the rear diff IS part of the transmission... so are the
driveshafts (all 2 or 3), all parts of the drivetrain downstream of
the crank being part of the power transmission.
