How do I fix the faulty transmission in my Ford Mondeo?

I recently bought a used Ford Mondeo and have been experiencing issues with the transmission. It seems to slip and jerk when shifting gears. Is there a quick fix for this or do I need to take it to a mechanic?

I had a similar issue with my Ford Mondeo and found that replacing the transmission fluid helped to improve the shifting. However, if the issue persists, it's best to take it to a mechanic for further inspection.

I've been a mechanic for over 10 years and have seen this problem with Ford Mondeos before. It's likely due to a faulty solenoid in the transmission. Take it to a reputable mechanic to have it replaced.

If you're comfortable working on cars yourself, you can try checking the transmission control module and wiring harness for any faults. Otherwise, it's best to have a professional technician take a look.
