I have been having trouble with my car's transmission. What are the signs and how can I fix it?

1.  Check your transmission fluid level to make sure it is not low or empty.
2.  Listen for strange noises coming from the transmission, such as grinding or clunking sounds.
3.  Test drive the vehicle and observe any jerky or uneven shifting.
4.  If you suspect a mechanical problem, take the vehicle to a qualified mechanic for an inspection.
