Stupid question, and you can call me dumb
I have always driven stick shifts and I always knew when I need to have the clutch replaced. This is my first auto transmission car and was wondering if the car has a clutch or something.. and how do I know when it needs to be replaced.
I always downgrade using the paddles to help the brake and yesterday after a long trip home it smelled like burned clutch
Besides changing the transmission fluid, what else do I need to do for the tranny maintenance?

Yes, all cars have clutches. In autos, it's just managed by the computer. I'm not sure when it would need to be replaced, but you would probably be able to feel the clutch slipping when shifting gears.
Not sure about the tranny fluid, but that might be all?

No, they don't. Most automatic transmissions like the 722.9, uses a torque converter and clutch packs. But there is no real clutch that is changing gears.

As mentioned before your transmission uses a torque convertor which is different than a conventional clutch as it uses fluid to transfer power from the motor to the transmission rather than a clutch and flywheel.
Tranny fluid and filter replacement is all that is needed for regular maintenance. You will know if something is wrong with your transmission as you will feel it slipping, chattering, bucking, or not working at all. If this is the case take it into a tranny specialist and they can diagnose the problem. I would be surprised if you actually damaged your transmission from downshifting to aid in braking unless you are downshifting at extremely high RPM's and holding it there.
Just because you "smelled" something doesn't mean anything is wrong, if you think otherwise take it in to be inspected.

503C43, thanks you made my day. I'm much less worried now. I'm planning to take my car to the shop as soon as I get my check from the Valet company that hit my car. I'm going to have all the tranny maintenance done, fluids, oil change, brakes replaced, calipers painted and new wheels.

what you were smelling was probably just overcooked brakes. Lots of guys have put way more power than you have through the 722.9 with no failure. It is a very under ratd from the factory.

is there anything wrong with driving around in manual and using engine breaking? i'm not driving around at sustained 7k RPM in 1st but I do frequently drive in M and rev up to 5-6k RPM before I shift and sometimes hold at around 2.5-3.5k RPM for 30-60s. usually when I break, I will downshift progressively as low as 2nd as I slow down from my original speed. it just sounds so satisfying

Thats really not a good idea. Brakes are far cheaper than tranny work.
No, its fine to let the engine brake in a single gear, but I wouldn't downshift when approaching a light. There is really no benefit and the resulting transmission wear is far more expensive to repair than the brakes.
