WHY WON'T THE GEARS CHANGE?
I have a 06 HHR. Last night suddenly the transmission would come out of what I think is passing gear. From takeoff it has a gives a whirling sound and will not change. it was rough geeting home at 10 to 15 mph. I didn't want to force it. Any suggestions on what is going on. it is 10 yrs. old and about 115, xxx. I hope that's not another tranny. I can't get it looked at til Monday.
