One problem related to transmission not go into gear has been reported for the 2006 Volkswagen Beetle. The most recently reported issues are listed below.
When in motion, the transmission fails to engage gears at appropriate engine speeds. Sometimes the engine revs way too high and slams into the next gear, producing dangerous jolts. Other times the gear fails to engage at all, resulting in complete loss of vehicle power. My vehicle was stranded in city traffic due to this temporary failure of the transmission to engage properly. The vehicle has been examined by qualified technicians and certain control parts have been replaced but the vehicle continues to display this defective behavior seemingly at random. I and others could have been very seriously injured because of this defect in the vehicle's drivetrain.
