AU auto transmission problems
I was wondering if somebody could give me more info on the auto transmission in the AU's. I have a late '99 AU Fairmont that's done 118,000kms.
Lately it seems to have been having some problems. Three of the doors have stuffed up and don't lock, the climate control panel at times decides to half light up, and just recently, I had problems accelerating. Last week, I stopped at the lights and when I went to take off, there was hardly any power!! The speed went up slowly but the revs just kept on staying up.
I took it straight back to the place I'd previously serviced it at, they checked it and told me it was the coil pack, which I paid $255 to fix. Two days later (Friday), it happened again! So this morning, I took it to another of this company's franchises (the one I serviced it at is other side of Melbourne, they were recommended to me) which is close to me and they pretty much told me after I explained the situation that the car is probably going into limp mode. They hooked it up to some computer thing and showed the code that was coming up, "code P0758 shift solenoid B electrical fault". So they recommended a transmission service which I did, and the oil was black! They reset the codes, and told me that if it happens again, then the solenoid probably needs to be changed. Just this afternoon, it happened again so I am pretty upset, and am going to deal with the original place on Monday for not finding this problem!
I know this solenoid problem is most probably because of the transmission oil, but could the problem be something electrical if the doors and the climate control panel is stuffing up? Would it show up when the check the cars computer? I just wanna know this before I pay to get the solenoid changed (though I'm gonna see what I can do with the original place, I rang the ACCC and I can't believe how much rights a consumer actually has).
Sorry for the long post, just would like to know what this solinoid actually does and how it fits in with the rest of the car.
Thanks if anyone can help
