Transmission oil change due to time?
I'm buying an Alfa with a C7 and an Allison 3000. The tranny had an oil change 4 years and 25k miles ago. Do you change the trans fluid due to time?

You have a unique opportunity to get the fluid analyzed to see the wear on the transmission before before you change the fluid.
I use Blackstone Labs for my coolant, engine oil, and transmission fluid analysis.
FWIW most of us change the fluids long before they wear out. If out of warranty, perhaps the lawyers' version of frequency can be ignored?
That's a good idea. How much do you send and how do you send it?
Go on their website and order a sample kit. Get your sample like the videos show on their website and it costs about $2 in postage to send it in. You include a piece of paper with your sample and they email you the results.
