Transmission on my 2011 GMC Terrian is slipping/jerking and I have less than 3000 miles on the vehicle. I've had it serviced 2 time s for this problem and of course they tell me ecah time it's not doing this when the mechanic drives. it. That does not mean it's not happening. I would like for my transmission to be replaced, because I know it's not me and there is something wrong with it. I am really disappointed in this with my SUV.
