Year, make and model would be helpful. If your car has a transmission dipstick, follow the procedure in your owners manual for checking the fluid.

If it is low, use ONLY the proper fluid for your car.

**Is there a warning/information light or message being displayed?** Assuming this is an automatic transmission then a design feature will cause certain problems with the transmission/engine to keep the car from up-shifting, known as “limp” mode.

Your problem could be fairly minor or major. **Certainly more information from you to us is required to receive any valuable suggestions other than wild guesses.**

Check your transmission fluid dipstick most that’s where most problems lie in.
