I have a 07 cobalt LT auto and have approx 36,400 miles on it. Should I get the transmission service done on it? Ive heard different mileages about when it should be changed/flushed. What mileage does gm recommend to have it done at?
Just curious if anyone else has noticed this. I have a 07 LT and not all the time but sometimes when I start up the car I get 5-6 knock sounds that sounds like its coming from the engine compartment. What could this be any ideas?
