hi i just bought a 2008 gmc sierra with the 5.3 vortec motor and was wondering if anyone has had any trouble with the newer 4l60e transmissions and also the idle seems kind of rough but nothing major like when i open the hood the engine shakes a little but not alot at all
alright i am glad to hear that and what do you think a dealership would charge to change the transmission fluid because i am away for work all the time and dont reallt have the time
