This is why you need a professional diagnosis. When I can't see or drive the car, I too am guessing.
As far as the years, I have a very reliable '88 Grand Caravan with 272,000 miles that I use to drag around a huge tandem axle enclosed trailer that's bigger than the van. This is the original transmission that has never needed a single repair. I also have a '95 model with half as many miles and it's on its second replacement transmission. They are seven years apart and are not the same transmission. The same is true about your cars, so don't try to draw any parallels there. The newer a car gets, the more complicated the transmission gets, and the more likely you are to have problems.
At the mileage you listed, it's not uncommon to need a transmission rebuild. From what you described, it sounds like that's what you need, but I want a specialist to tell you that. Don't go by what I'm guessing.
If I'm right, continuing to try to make the car move with a slipping transmission will seriously overheat all the rotating parts inside it and result in many of those parts needing to be replaced too.
