If it is light, it causes the transmission to stall, and heavy, the transmission will be scrapped due to impurity blockage. Factors in the cleanliness of automatic transmission include unclean cleaning burrs, dust, packaging, assembly environment and other factors. How to systematically and comprehensively analyze the factors affecting the cleanliness, so as to scientifically formulate the basis for determining the cleanliness and adopt a reasonable cleanliness detection method, which is very important for controlling the cleanliness of the automatic transmission and improving the performance of the transmission. Therefore, this paper systematically analyzes the factors affecting cleanliness, control methods, solutions, the formulation of cleanliness standards, detection and analysis methods, detection process processes and equipment, which plays a key role in understanding the cleanliness problem and systematically solving the cleanliness problem.
