Typically if it is caused by the TCC solenoid (wich is possible from what you described). If thats the case your check engine light will be on and the solenoid(s) will likely need to be replaced. Here are some steps you can take to diagnose and address the problem though:
Check Transmission Fluid Level:
Ensure that the transmission fluid level is at the correct level. Low fluid levels can cause problems with the torque converter.
Transmission Fluid Condition:
Check the condition of the transmission fluid. If it's dark or has a burnt smell, it may indicate a problem with the transmission.
Transmission Fluid Exchange:
Consider performing a transmission fluid exchange if the fluid is old or degraded. Fresh, clean fluid can sometimes resolve shifting issues.
TCC Solenoid Inspection:
The TCC solenoid controls the engagement and disengagement of the torque converter clutch. If it's faulty, it can cause the symptoms you're experiencing. Inspect the wiring and connections to the TCC solenoid.
Scan for Transmission Codes:
Even if the Check Engine Light is not illuminated, it's worth using a diagnostic scanner that can read transmission-specific codes. There might be pending or intermittent codes that don't trigger the check engine light.
Perform a Throttle Body Cleaning:
A dirty or clogged throttle body can affect the engine's ability to maintain a stable idle. Cleaning the throttle body may improve idle stability.
Idle Air Control Valve (IAC) Inspection:
The IAC valve regulates the amount of air entering the engine at idle. If it's not functioning correctly, it can lead to stalling. Check for any issues with the IAC valve.

Ensure that the transmission fluid level is at the correct level. Low fluid levels can cause problems with the torque converter.

can be indicative of an issue with the torque converter or the torque converter clutch (TCC) solenoid. The torque converter is responsible for transmitting power from the engine to the transmission and helps the vehicle come to a stop without stalling.
If there's an issue with the TCC solenoid or the torque converter itself, it can lead to stalling when coming to a stop. The fact that there are no error codes could indicate an intermittent problem or a sensor-related issue.

Hi there,
Stalling or hesistation in your vehicle's engine operation can be caused by a variety of factors. Still, it is best to run a diagnostic to generate a trouble code. Here are some of the possible problems:
1. Idle air control valve issues.
2. Torque converter clutch issues (TCC).
3. A bad Mass air flow sensor
4. Throttle body issues.
5. Vacuum leaks.
Click the following link from our website's resource database blog for more details of each mentioned parts (https://www.carparts.com/blog/guides/). If a trouble code is generated (using a OBD II scanner tool). Simply enter each code on the search box to access the detailed explanation and DIY videos on possible solutions. I hope this helps!
