Again, I'm not sure it's worth the cash if the car spends most of its time in daily driver use.

I think if you have anyquestions about what a torque converter is you should check out the older v8 and domestic hotrod forums, unlike the low torque high rev import world. Classic v8's have plenty of power to run torque converters and auto trannies. Read about them on some of the classic hot rod sights. This would better explain to you what one is, and how it works.

With this info you can then decide for yourself.
