Transmission not working properly and transmission light is on

Good morning,

Do you know the code for the transmission light? That will help me narrow the area of failure for the issue.

How long since you serviced the transmission? I would start by changing the fluid.

This could also be the valve body or shift solenoids. This is why we need the code. You can have a parts store read the code for free.
