Guys: I have a 2014 Impala LTZ (6 Cyl). I have 60K miles on it and the dealer wants $200.00 to change the transmission fluid, so I guess I'll do this myself. I guessing that a basic drain and refill will be enough. I'm also guessing that after I drain it I can refill it through the dipstick area. Does anyone have a picture of where the drain plug is?
