Transmission slipping/jerking on my GMC terrian SUV-sle model. I have taken it to the deal 2times for the same problem. They say there's nothing wrong, but it's still jerking, it's happen when the gear shiting (it's an automatic) the change over is not smooth. The mechanic says it's doesn't happen when they drive it of course, but this deos negate the fact that it is happening. Please have someone check into this problem. Because I'm sure it's happening to other Terrain owners.
