Does anybody know if they make an automatic overdrive trans for the 3cyl 1.0?

I have never seen one. I think the Canadian sedan with the 1.6 had an AOD and I think it is the same bellhousing but getting the controller and the computer to get along might be a bit challanging.

no such luck. 1.6 bellhousings have a few differences. If you're a machinist, it would be no problem. But no, no 1.0 4 speed automatics were ever made.
