my 2.5xt has 105,000 miles- general use. how many miles can I expect till ovhaul

It's a mechanical item...ANYBODYS guess...'95 camry I treat like crap , 339,000+ miles on it and still going (red line every day) strong , with original trans. Only suggestion I'd make is to cut back to no more than 4000 miles between changes , and use factory oil filter. Trans also , I'd say same , use factory fluid and if it has a filter that can be serviced , do just that and fluid change every 60-90K miles. DO NOT FLUSH trans. (MY OPINION).Enjoy the ride.
