In owners' own words
No major events leading up to the failure, just average city/highway driving with little to no aggressive acceleration.
My car slams into gear from a dead-stop. It grinds very loudly when then TCC is applied. Shifts hard and shakes very violently, sometimes to the point where it is almost undrivable.
I have a 2006 Pontiac grand Prix gxp with the 5.3L V8 engine. The car has less than 104,000 miles on it and the transmission does not always engage first gear when attempting to accelerate from a stop.

Recalls for the 2006 Pontiac Grand Prix: 2
This defect can affect the safe operation of the airbag system. The key fob (if applicable), should also be removed from the key ring. In these models, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine. If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.
A potential material or design defect could result in the steering knuckle breaking in the hub area. A broken steering knuckle could result in loss of steering control and a possible crash without warning.
A recall may cover only some cars of a model year; the campaign size counts every model and year it lists. Enter your VIN at nhtsa.gov/recalls: dealers fix open recalls free.
