I know about this, I've done it to get as low as 60:1 gear ratios for crawlers.

My thing is that I need something that I can shift on the fly, and it needs to have two very specific gear ratios.

I actually have also considered using an old automatic transmission w/o the torque converter as a sealed unit. (They don't need the fluid cooled if it's not going through a torque converter or being shifted up/down constantly.)

The problem is that there's only one 2-speed solution that I know of, and I don't think it has a gear that's close to 1:1
