So hi, I have a 2000, automatic Grand Am SE with 161,000KM in her and everything seemed to be working fine but as I was driving it today my speedometer just stopped working and when I try to get her up to second gear she kind of jerks forward, if that makes sense? Also, today when I was driving she couldn't gear up at all, she just went from first to second to third to fourth gear without picking up any speed.
I'm not a car savvy person at all but I'm pretty sure it has something to do with the transmission?
Any help would be greatly appreciated!
