Wanna change the tranny fluid (Flush) and maybe filter.
Its a 09 with 3.5 L engine.
Dealer wants about $ 285 + gst they use dextron 6 + gm filter.
One tranny shop wants almost the same another said $ 128 with filter, claims to use syntetic oil.
Claims that they recommend you change that oil every 20000 KM Ehhh
