That is a really good explanation. I have some vague images of a torque converter in my head from seeing such images on the internet. But I've never taken one apart. To me, the whole converter and automatic transmission is magic and wizardry inside a metal housing.
I'm getting my mind wrapped up into replacing the tachometer. Right now its a vintage Suntach? unit. Most people like these, I guess for the nostalgia. But I'm not really down with it. And it's located above my left knee and I don't like that either. I'm wanting to upgrade the tach and put it and the AFR gauge up on the dash.
