If you have a manual transmission, a worn out or defective clutch could cause it to not shift. There could also be internal damage to the transmission, causing the gears to not mesh together and slip. The shift linkage may also be loose, and preventing the transmission from shifting.
If you have an automatic transmission, low or burn fluid can cause it to slip in gear or not shift at all. The transmission uses a pump to pump the fluid and maintain hydraulic pressure, so if the pump is broken or leaking the transmission will not shift. The fluid passages can also become clogged and cause loss of pressure. Many new vehicles use electronic solenoids to assist with shifting, and if the wiring harness or vehicle's computer stops working correctly, the transmission will not shift.
In either case, you should take the vehicle to reputable transmission repair facility, where they can properly diagnose the cause of your issue.
