problems with electronic transmission? help!
Hi, I own a 2006 G6 automatic model and recently, my transmission (I am guessing electronic box?) has started to make huge scary ''noise'' when shifting from 1 to 2. ( felt same as skipping a shit with a manual car). The check engine button lighted up, then the next morning, everything was gone, check engine disappeared and noise was gone. It started to do it again a few weeks later, but worst this time, between every shift. I have been told it could be my electronic transmission controller. Anybody experimented this problem before?
It first happened when it was raining outside, but now it's any time I do a long road (an hour +). The dealer says they cannot find my problem, did the scan twice but nothing was showing up.
I am a girl and know NOTHING about car. I have to make a 4000 KM trip in 3 weeks and would really like to solve this problem before leaving!
Anybody can help me? What can it be?
