8 Speed transmission slipped as I was going around a corner causing my 2017 Colorado stop suddenly causing the cars behind my to swerve to avoid me. Then the excellerator linkage or something caused the engine to rev out of control when the transmission finally stopped slipping causing me to run the truck off the road. This slip and then uncontrolable exeleration has occured 3 times since I bought it, This truck is a LEMON!

Hard shifting, missed shifts, shudder from TQ converter. For six months the vehicle has been shifting had at random times during shift sequences. Hard shifts occur on both moderate acceleration and hard acceleration. Shifts can only be described as sudden and violent, feeling something like a U-joint failure, broken transmission mount, or a clutch slipping and then slamming into gear. The hard shifts occur and any speed and any gear, but are very noticeable around 3rd / 4th. The TQ converter slips on acceleration only. Has been in the dealer 3 times for a total of 7 days so far with one technician claiming it needs a new TQ converter and possibly a new transmission. Other techs claim they can't find the problem. No codes, no lights. Dealer claims they can feel the problem but have failed to diagnose it. Failure of this could pose to be a serious safety issue if it happens at highway speed in traffic. GM has the inventory of 6L50 transmissions on lockdown.
