when hot, it occasionally hard shifts from 1st to 2nd
2012 gmc terrain slt. When this car is hot, it occasionally hard shifts from 1st to 2nd. Of course, when I took it to the selling dealer's service dept., they could not observe this ?!?!?
Is this repairable? What is causing this when it is hot?
Has the trans ever been serviced? If not try that first and give it a day or so for the new fluid to get mixed in good and see if that helped, if it does not help then the most common problem is sticky shift solenoids inside the trans, a good tranny shop can do this job a lot cheaper than a dealer.
