Possible causes of impact when engaging a gear in an Audi automatic transmission:
*Low Transmission Fluid (ATF): Make sure the ATF level is at the proper level as directed in your owner’s manual.
* Contaminated or old transmission fluid: ATF should be changed regularly (usually every 60,000-80,000 km) to prevent contaminant and debris from accumulating.
* Defective automatic transmission solenoid or valve: These components are responsible for shifting gears and can cause shock when faulty.
* Clutch Problems: The clutch in an automatic transmission can become worn or dirty, causing slipping and slamming.
* Faulty Torque Converter: The torque converter is what makes gear shifts smooth and can cause knocking if it is faulty.
* Mechanical problems within the automatic transmission: Serious mechanical problems, such as worn gears or bearings, can cause significant shock when the transmission is engaged.
Diagnostics and repair:
*Check ATF Level: Use the transmission dipstick to check the ATF level and make sure it is within specifications.
* Replace ATF: Replace ATF regularly as directed in the owner’s manual.
* Scan for trouble codes: Connect a diagnostic scanner to your vehicle to read trouble codes that indicate problems with the automatic transmission.
* Check the system for leaks: Inspect the automatic transmission and surrounding components for ATF leaks.
*Seek professional help: If you suspect a more serious problem, contact an authorized Audi service center for diagnosis and repair.
Note: Ignoring shocks when shifting into gear can lead to further problems with the automatic transmission and costly repairs. It is important to diagnose and fix the problem in a timely manner.
