Thousands of driver's experiencing transmission as you approach a light, stop sign, merge into traffic, driving through a neighborhood the transmission at low speed will produce a hard hit, slam. It feels as if you have been rear ended. Concern is that you will be thrown into oncoming traffic, through a red light, stop sign or at worse the rear end of the car in front of you. It just a matter of time before someone is seriously hurt.
Because this is hard to produce, GM/Chevy is refusing to address unless duplicated. Please ask GM/CHEVY for 2014/2015 transmission repairs/replacements for cars built prior to 11/01/15.
