When i got my daily it had a blown auto so i threw one in i had sitting that came with a motor i bought and that fluid had never been changed and i threw fresh fluid and a filter in it and it shifted perfectly. That trans had at least 150xxx and worked great til i pulled it recently.
I've also changed trans fluid on previous cars and they're all really fairly easy and simple to do.
changing fluid can be risky. as they years run up on the trans the wear on the motor can shave the gears...... changing the fluid once the fluid is beyond lube point to allow shaving......... once the shaving has occured changing the fluid reduces reliability(not kill it) because the metal shavings have built up on the gears now are being flush out.
that being said.......... auto trans are up forsale for free ALL THE TIME I would drive it till it died and then worry about it. maybe even just keep a transmission in the garage for a back up when you catch a free one for sale.
