Don't see how this could be possible. If you study a 2 speed auto like an Ultramatic, and compare it to any 3 speed, you will see the case of the 3 speed is much longer. The guts of the transmission contains two planetary gear sets instead of 1. There just isn't room in an Ultramatic case for more gears.

Plus you are talking about using metric parts in an inch case. They are designed with 2 completely different measuring systems. The chance of parts interchanging from one to the other without machine work is practically nil.

I would love to be proven wrong. I get a kick out of wild ideas. But until I hear more details my guess is that it's just a pipe dream.
