Welcome to 2CarPros.

Are you able to move the shift lever? Also, if you can move the shift lever, have you checked the transmission fluid to make sure it is clean and full?

Here are the directions for your vehicle.

TRANSMISSION FLUID CHECKING PROCEDURE
1. Start the engine and operate the vehicle for 15 minutes or until the transmission fluid reaches an operating temperature of 82 - 93°C (180 - 200°F).
2. Park the vehicle on a level surface. Apply the parking brake and block the wheels.
3. While the engine is idling and with your foot on the brake pedal, move the shift lever through each gear range, ending in Park.
4. Check the fluid level, color and condition (transmission fluid conditions are diagnosed by color). The fluid will be higher on the fluid level indicator when the transmission is cold. Conversely, the fluid level will drop when it is checked at operating temperature.
5. If it is necessary to add fluid, DEXRON(R) III Automatic Transmission Fluid is preferred. DEXRON(R) III is an acceptable substitute.

The picture below indicates different fluid conditions and possible causes. Check this and let me know what you find.

Take care,
Joe

My mechanic drained the fluid without dropping the pan. Nor did he check for leaks. My car drove for minutes then it went back stalling. The guy drove it putting it in 3. Was this safe?

Welcome back:

If you are referring to third gear (3) that won't hurt anything. I would recommend driving really fast in that gear.

Let me know what has been suggested and what is now happening.
