There are a few things that could be causing the issue with your Toyota Corolla not shifting gears properly. Some potential causes could include:

A faulty shift solenoid: Shift solenoids control the flow of transmission fluid, which is necessary for proper gear shifting. If the solenoid is faulty or stuck, it could cause shifting issues.
A damaged or worn clutch: If the clutch is worn or damaged, it may not be able to engage and disengage properly, which can cause shifting issues.
A transmission control module (TCM) issue: The TCM is the computer that controls the transmission and gear shifting. If it is malfunctioning, it could cause shifting issues.
Transmission fluid level or quality: If the transmission fluid is low or contaminated, it can cause shifting issues.
It's worth noting that these are just a few potential causes, and there could be other issues at play as well.
