Toyota calls its ATF lifetime fluid. Asin, who makes the transmission, does not.
10K OCIs are more of a marketing thing, IMO. Toyota did it to keep up with other car companies.
My guess is, they expect customers to keep their cars on an average of 100K to 150K.
5K OCI is cheap insurance. I leave the filter on for 2 or even 3 services and use the MityVac for 15 minute, easy peasey, no mess oil changes.
I have 2 cars with over 210K that I never even check the oil level; there is no need to.
Agreed 100%. Oil change can be done for $30 and very little effort for most vehicles. In 10 years just doubling up OCIs is barely any expense.
Toyota is in the same camp as other makers who've stretched the truth to list lower maintenance costs on paper. This makes them untrustworthy.
"Lifetime" is a dishonest word as it's used by many auto makers, not just picking on Toyota. Outside of warranty is "end of life" and in accounting terms, it's a fully depreciated asset. No longer the auto-warrantiers problem when engine issues (or transmission, etc.) develop after X miles/years.
I want my vehicles to last many decades as 300-500K miles or more. If possible. Best ROI.
With Toyota there are 2 documented 1,000,000 Tundras. I think they were 4.7L and /or both were 5.7L engines, 2007 models, dealer serviced but at very regular and lower miles. The OCI interval at that time was 5k miles or 6 months. Bottom line if you want your vehicle (any vehicle) to perform well long term stay within reasonable limits. For low mileage and highway, I think 6 months is probably too aggressive and unnecessary, but over 5K is pushing it too much IMO. I think the time is there to remind people to change it, b/c a longer OCI time interval, if missed, could cause a much too long 2-year or longer change interval.
I'd like to hear from others about their views on time, for low miles driving. I have a "duty truck" that rarely gets driven.

"Generally, the Toyota Tundra V8 engines have 5000 mile or 6 month maintenance intervals."
