Possible reasons why the automatic transmission jerks after an oil change:
1. Wrong oil:
*Make sure you have used the correct type and amount of oil for your transmission. The wrong oil can cause lubrication and friction problems.
2. Low oil level:
* Check the oil level and add if necessary. Low oil levels can cause insufficient lubrication and damage to the transmission.
3. Contaminated oil:
*If the oil has not been completely drained and replaced, residual old or contaminated oil may cause shifting problems.
4. Problems with the filter:
*A clogged or damaged filter can restrict oil flow and cause jerking.
5. Electrical problems:
* Faulty sensors or wiring can affect transmission performance and cause jerking.
6. Mechanical faults:
* Wear or damage to internal components such as clutches, brakes and planetary gears can cause shifting problems.
What to do:
* Check oil level and quality: Check the oil level and make sure it meets specifications. If the oil is dark or dirty, change it again.
* Clean the filter: Replace the transmission fluid filter.
* Get it diagnosed: Have your vehicle serviced to diagnose electrical and mechanical problems that may be causing the jerking.
*Avoid aggressive driving: Until the transmission is diagnosed and repaired, avoid sudden acceleration or gear changes.
* Reset: Some transmissions have a reset feature that can help resolve shifting problems.
