It's easy to install but youll need a buddy.with.you to install it or at least some wood blocks like i did to level the hood to install it insert one side at a time and if you choose to go aftermarket reinforce the metal bracket that holds the hood or add hood pins
Same thing happened to my 09 cvt to my 2nd cvt. And I even kept up with the maintenance on time.
If you're the original owner and are still under 100k miles then you should be able to replace it under warranty. If you're the 2nd owner then you have warranty till 60k. owners beyond that are sol. So if you do have to replace it on your own then be sure to get a "years" matching tcm (transmission control module) and (i think) ecu as well. Your 09 tcm and ecu may not be compatible with the later model CVT and may make it shift abnormally. I believe they made some revisions in the programing for the later years but I can't quite find the source of where i read this. so take that with a grain of salt but its worth looking into.
(seems like im only here to drop my 2 cents in about cvts lol)
