* Safety: A shaking car could indicate a serious problem, and driving it could be dangerous.
* Accuracy: Diagnosing car issues requires hands-on inspection, listening to sounds, and using specialized tools. I lack the ability to do any of that.
* Complexity: There are many potential causes for a car shaking, ranging from simple issues like a loose engine mount to more complex problems.
Here's what you should do:
1. Don't drive the car if it's shaking excessively. It's a sign something is wrong.
2. Contact the mechanic who installed your engine. They may have some insights or be willing to look at the car again.
3. Take your car to a reputable mechanic. They can properly diagnose the issue and recommend the best course of action.
Possible causes of a shaking car in park (after a new engine):
* Loose engine mounts: The engine mounts hold the engine in place. If they're loose, the engine can vibrate.
* Transmission issues: The transmission might be malfunctioning.
* Driveline problems: Issues in the driveshaft or axles can cause vibrations.
* Engine problems: A problem with the engine itself, even after a new install, could lead to shaking.
Don't hesitate to seek professional help.
