What are the consequences of not changing manual transmission fluid?

[SanRiley]

Failure to change transmission fluid for an extended period can lead to the following consequences: 1. The quality and performance of the fluid will deteriorate, reducing its cleaning and lubrication functions. 2. It will accelerate the wear of transmission components, making the transmission more prone to malfunctions. Most transmission failures are caused by deteriorated transmission fluid. Compared to the cost of changing transmission fluid, the repair cost for the transmission is significantly higher. Here is some relevant information: 1. Both automatic transmission fluid and manual transmission fluid need to be replaced. Generally, automatic transmission fluid should be changed every two years or after driving approximately 40,000-60,000 kilometers. 2. Most manual transmission fluids require replacement every three years or around 80,000-100,000 kilometers. However, the specific timing depends on the condition of the transmission and the usage of the fluid. If you experience issues such as difficulty shifting gears, jerking, lack of acceleration power, or unusual noises from the transmission, it may indicate a problem with the transmission fluid, and it should be inspected and replaced.
