Non synthetic ATF has much better solvent properties -- in those days it was a necessary evil to work properly at high temps. Hence it didn't protect as well as modern synthetics because of that solvent content. Synthetics don't have much value as a solvent, so as a cleaner they aren't very efficient.

Interesting. I always thought synthetic oils were good solvents.

Any way to tell if your ATF is natural or synthetic? Or are they all synthetic now?

It usually states it on the label whether it's synthetic or not. Synthetics use a lot of compounds derived from natural gas. In fact some synthetic oils are almost completely manufactured from natural gas compounds. Hardly any traditional solvents involved in the process.

I'll have to start checking labels. I heard that Mobil 1 full synthetic is made from natural gas.
