I am very seriously considering installing a 3 speed with overdrive manual trans. in the frame off rebuild of my '71 Chevy stepside. It currently has the stock 250 c.i. with the 3 spd manual trans. I have located an o/d trans. , but does anyone know how they work, I mean, are the later o/d trans. electric and cable operated? Can anyone give me a brief "Overdrive for Dummies" course? Any help is appreciated.
Thanks, Bob
