How do I troubleshoot the transmission in my Ford Ranger?

I've been experiencing some issues with the transmission in my Ford Ranger and I'm not sure how to fix it. Can anyone offer some advice on how to troubleshoot this problem?

Check the transmission fluid level and make sure it's at the proper level. If it's low, top it off and see if that fixes the issue.

You may have a faulty sensor or solenoid. Take your truck to a mechanic for a diagnostic test to pinpoint the issue.

If you're experienced with automotive repairs, you could try replacing the transmission filter and fluids. But if you're unsure, it's best to leave it to a professional.
