Synthetic ATF?

Synthetic fluids reduce friction, thus heat and wear. Do you need them? No. Is it a better, higher quality product? Yes. I use Amsoil synthetic ATF in my transmission because I have several thousand into it. I use Amsoil Z Rod synthetic oil in my motor for the same reason. You can use regular fluids, but we spend tons of money building these cars, why go cheap on their life's blood?
