Causes of Reverse Gear Impact
1 Answers
A slight impact sensation is quite normal, mainly caused by the engagement of the torque converter with the engine. However, if the impact is severe during gear shifting, the following faults may be present: 1. Insufficient transmission lubricant: Some vehicle models are prone to transmission oil leakage, which can lead to inadequate internal lubrication, resulting in a strong impact sensation during gear shifting. 2. Excessive impurities in transmission lubricant: If the transmission lubricant has not been changed for a long time, dirt can accumulate inside, significantly affecting the smoothness of gear shifting. 3. Delayed automatic control valve operation: If the automatic control valve does not shift gears promptly, the delay can cause substantial impact on the transmission.
