What is the reason for the abnormal noise in the Audi Q5L transmission?

[StLucy]

Audi Q5L transmission abnormal noise is due to bearing wear and damage. Specific reasons for abnormal noise in car transmissions: Bearing wear and damage. Loose bolts on the transmission housing. Vibration during use can loosen the bolts, so it is important to regularly check the looseness between the gear lever and the gear shift fork groove in the manual transmission. Solutions for transmission abnormal noise: Long-term failure to replace automatic transmission fluid can cause the fluid to become thick and lose its fluidity, resulting in direct friction between components without a protective layer, thereby exacerbating mechanical wear and causing abnormal noise. Use of inferior automatic transmission fluid. Inferior transmission fluid has poor temperature resistance, is prone to oxidation, and can form sludge and residue, clogging the filter and oil passages, increasing friction between internal components of the transmission and causing abnormal noise in the vehicle; Abnormal gear meshing clearance. Wear of transmission components or the use of low-precision parts during replacement can result in excessive clearance; Gear clearance is too tight during assembly. Metal peeling on gear surfaces, gear tooth breakage, or misalignment during assembly; Insufficient lubrication due to inadequate lubricant. The corresponding lubricant should be replaced; Water ingress into the transmission, if not repaired in time, may lead to abnormal noise issues over time.
