Possible causes of automatic transmission malfunction after changing the oil:
1. Using the wrong type of oil:
*For proper operation of the automatic transmission, a specific type of oil is required. Using the wrong oil can cause shifting problems and damage internal components.
2. Contaminated oil:
* If the oil used is contaminated, it may contain debris or metal particles that can clog the passages and damage automatic transmission components.
3. Insufficient oil:
* Insufficient oil level in the automatic transmission can lead to overheating and insufficient lubrication, which can damage components.
4. Air in the system:
* If air gets into the automatic transmission system, it can cause bubbles to form, which can interfere with oil flow and reduce its efficiency.
5. Problems with the filter:
*A clogged or improperly installed filter can restrict oil flow and cause shifting problems.
6. Damaged components:
* Changing the oil may reveal hidden problems with automatic transmission components that were already present before the change. These problems may appear after an oil change due to changes in operating conditions.
7. Defective operation when changing oil:
* Improperly performing the oil change procedure can lead to damage to automatic transmission components. For example, improper draining or filling of oil can create problems.
Actions to be taken:
* Check oil level and quality: Make sure the oil level is correct and that it is clean and not contaminated.
* Use the correct type of oil: Check your owner’s manual or consult a mechanic to determine the correct type of oil for your automatic transmission.
* Diagnose the problem: Take the car to a mechanic to diagnose the automatic transmission problem. Diagnostics may include inspection, testing, and scanning fault codes.
* Fix the problem: Once diagnosed, the auto mechanic will fix the problem by repairing or replacing the damaged components.
