Overdrives were an option on most Brit sports cars back in the day because of the way they were geared to take maximum advantage of small engines made them buzzy on the highway. It’s a very desirable feature in these modern times.

Yep, what this thread discusses is basically what I remember my dad saying.

OD is a separate thing from the transmission (not just an extra gear or two) and is operated by a switch.

And, the car had a 4 speed, but the OD could be engaged in 3rd or 4th gear essentially turning the car into a 6 speed.
