What causes failure to change gears?

My car has 100000 miles.
My car has an automatic transmission.

Hi there, and thanks for writing in.

There are many possible causes of your transmission shifting issue, though it’s impossible to tell what’s wrong on yours without first inspecting it. It could have a low fluid level, it could have a failed valve body, or it could have another failed internal component. The best thing to do at this point in time would be to have the engine and transmission scanned for faults, and proceed from there. You should have a qualified professional, such as one from YourMechanic, thoroughly diagnose your shifting issue for you.
