That's excellent news. IMO the trans is the most advanced of all fluid maintenance. Once you lean how to do the axle fluid, engine oil, and TC oil, you'll save hundreds if not thousands of dollars over the life of your Jeep. If you don't mind dirty hands, no general maintenance is difficult.
Tire rotations are easy too. You save $10 per rotation doing it yourself. Doesn't seem much but it's an average of $30-$60 a year. It adds up.
Brakes are easy too and save a ton of $$$ doing it yourself. Most shops charge $100-$200 per axle. You can do it for a fraction of that.
Jeep girls rock. Keep learning and don't stop playing with stuff. None of it is as hard as it looks
