Check the transmission fluid level to ensure it's at the proper level. After that, the TCM is responsible for controlling the transmission's shifting. If there's a problem with the TCM, it could lead to manual shifting issues.

Hi there,
Here are several reasons why you might have to manually shift gears in your 2010 Chevy Impala, which is typically an automatic transmission:
1. Low transmission fluid. Less than standard fluid inside the transmission can disrupt hydraulic pressure and lead to erratic shifting or gear slippage.
2. Defective/faulty transmission components. There could be faulty transmission solenoids, clutches, or sensors within the automatic transmission preventing automatic gear changes.
3. Torque converter issues. A bad torque converter would prevent smooth gear changes and require manual intervention.
4. Transmission fluid contamination. Dirty or contaminated transmission fluid can cause internal damage and shifting issues in the long run.
