How do I diagnose and fix a faulty transmission in my Ford Fiesta?

I've noticed my Ford Fiesta is having trouble shifting gears and there seems to be a delay in acceleration. What could be the cause and what steps should I take to fix this issue?

Based on your description, it sounds like your transmission may be failing. It's important to have this issue addressed as soon as possible to avoid further damage to your vehicle. I recommend taking your Fiesta to a trusted mechanic for a diagnostic test.

I had a similar issue with my Ford Fiesta and it turned out to be a problem with the transmission fluid. Make sure to check the fluid levels and quality, and if necessary, have it changed. This should help improve shifting and acceleration.

If the transmission fluid levels are fine, then it's possible that the issue could be with the transmission control module. I suggest taking your Fiesta to a dealership for proper diagnosis and repair.
