Transmission Not Go Into Gear problems of the 2002 Volkswagen Beetle

Over the past two months, I have experienced problems shifting in between gears. The problem began on a road trip to houston, TX and was stuck on a back highway in low gear in the middle on nowhere. After bringing the car to a stop and restarting the vehicle it worked for some time but the issue progressively got worse over the last two months. I live in nacogdoches, TX where there are many hills throughout town, this past Friday on my way home from school my car would not shift gears and I could not get over the hills. Another car came over the hill and almost hit me as the speed limit is 55 mph in that area and my car was not even moving as I hit over 6000 rpm and I could not move forward to climb the hill. Now the vehicle will not even move forward once it was brought to my driveway, no matter how many times I have restarted.

While traveling on the highway the vehicle will jerk back and forth. The transmission has froze and will not shift gear. Please fill in additional information dealer is aware of the problem. Ts.
