What causes the rattling noise when shifting into reverse gear in an Excelle automatic transmission?
1 Answers
The reasons for the rattling noise when shifting into reverse gear in an Excelle automatic transmission: 1. Cold start: When starting a cold engine, the transmission fluid has poor fluidity, and the internal gears are not sufficiently lubricated, resulting in abnormal noises during gear shifting; 2. Aged transmission fluid: Like engine oil, transmission fluid needs to be replaced regularly. Aged transmission fluid leads to reduced lubrication, causing noticeable impact and noise during gear shifting; 3. Worn transmission gears: Some owners may experience gear wear due to improper vehicle usage, leading to metallic noises when shifting gears with worn gears.
