A handful of instances over the past month, my 2009 jeep wrangler violently and unexpectedly pops out of first gear upon acceleration. This could result in a rear end collision, potential accident while crossing traffic lanes or upon acceleration onto a highway like the sawmill parkway where you enter the highway from a dead stop. In addition to the potential catastrophic results due to an accident, the shifter when it violently disengages can result in a damage to the drivers hand or fingers. My fingers to a significant hit the first time I experienced the problem. Through a search on the internet, I see that this has happened to other wrangler owners.

2009 jeep wrangler x pops out of first gear as the vehicle accelerates from a complete stop. As this is occurring in first gear from a stop it is usually when the vehicle is merging into traffic or at a stop sign, thus creating the potential for a broadside collision or rear end.
2009 jeep wrangler with six speed manual transmission. On start from standing stop transmission will slip actual "pop" out of first gear. Problem is random and intermittent but will occur two to three times during a driving day. Car has left me vulnerable in traffic as I try to re-engage transmission to get out of oncoming traffic's way. Search on web indicates it is a known problem to owners of 2007-2009 jk wrangler owners but jeep has not issued any tsb or other fix. Dealer will not repair intermittent problem. I am going to get killed in this thing if they don't fix it.
1) during the period of placing the manual 6 speed into first gear, the gear will sporadically pop out and abruptly back into neutral. It does not seem to make any difference as to the temperatures nor conditions outside. It occurs under normal driving conditions. (state/city road 2wd) 2) the failure is that without warning in a sporadic state, 1st gear while engaged and moving at either 1 - 10 MPH will abruptly pop out of first and land in neutral with a loud thud when occurring. This is a dangerous issue in that if one is pulling onto a road to go with or against traffic and this occurs, the end result could be life threatening. If one pulls onto a road and a car is moving at 40 MPH and is unable stop, a high probability exists whereas a t-bone accident could occur thus causing death. Within 2500 miles, this incident has occurred 10+ times. 3) a service visit is currently scheduled, although if it is a collar or synchronizing issue, it will as likely as not be repaired. The incident does not duplicate time after time. As I mentioned, it has occurred it 10+ times within 2500 miles. Roughly 2.5% of the time within the 0 miles to 2500 miles this issue has occurred. However, this is not the most accurate result due to 1st gear only being utilized when pulling out from a stand still. A vast majority of mileage is added within the 4 - 6 range. 2009 jeep wrangler x, 2dr.
