I found out that mine has the optional 3.54 axle ratio, so that lowers the road speeds that it shifts.

Probably a good thing considering I live in the mountains at 7000 feet. I found out by surprise that the converter locks in low range, only when the gear selector is in manual low. That's neat. Useful, too.

The Ultramatic never stops amazing me. So advanced and smart for the time.
