As far as I know from hanging around the forums since '01, there is no automatics specifically designed for the Samurai and it was not an option for the North American market Samurai. I would hazard a guess that from '95 back, and automatic SJ-413 did not exist as an option anywhere.
You can bolt up transverse automatics to the 1.3 but that really doesn't help much...
Most folks do a 1.6 engine/transmission transplant to get an automatic Samurai.
Any better guessers than me??
