I'm new to the forum so I'm not sure if this is the right place to post this, but I have a 2012 patriot with an automatic CVT transmission. The car is almost to 100k miles and she's starting to shift hard in the first 3 gears. Its never had a transmission fluid change. My first question is just do I need to get that changed? I'm assuming yes. My next question is how long is my jeep gonna last? As I've said, it has almost has 100k miles and its had virtually no issues. Its had all of its oil changes on time and I get semi synthetic instead of standard. It has a new battery and new tires. My hope is at least 200k miles, because I'm about to start college and I want it to last at least through the first 4 years and I drive alot. So how long should I expect it to last and what can I do to ensure that she lasts as long as possible.
