problem please help
A code check would be a good place to start, could be a neutral switch bad, speed sensor defective, wiring problems, or even the BCM.
If the speedo isn't working, the speed sensor potable isn't working. If that isn't working the trans won't shift. Usually defaults to 3rd gear but can also be stuck in first.
