If you're just looking for an indicator of transmission health, pulling the pan will give you that, along with having the fluid analyzed by a outfit like Blackstone Labs.
If you're looking to see how far along in the life cycle a specific transmisson is, or what some builder put in as far as aftermarket parts, then you're probably gonna have to pay someone for an inspection.
As long as you have some of the old ATF you could have it analyzed by someone like Blackstone labs, here is their website info for transmission fluid analysis:

Automatic transmissions ask a lot of the oil. Not only does the oil lubricate and clean internal parts, but it also functions as a hydraulic oil to operate various components.
Transmission oil can be contaminated with metals, solids, and moisture, and those contaminants need to be removed before they cause problems. Conversely, a test of your transmission fluid may reveal that it’s still in great condition, and you don’t need to change it as often as you thought.
There’s no easier way of knowing what’s going on in the system than oil analysis. We can tell you if the oil needs to be changed, if it’s contaminated, or if there are any problems at hand. Request your free kit today and make sure your drive train is wearing as it should!
