What are the levels of water ingress in the Emgrand transmission?
2 Answers
There are three levels of water ingress in the Emgrand transmission, classified as severe, moderate, and mild. Severe water ingress: Severe transmission water ingress can be directly observed through oil drainage. When the transmission oil is drained, the color and viscosity of the oil-water mixture can indicate significant water ingress. Moderate water ingress: The presence of white sediment in the oil pan indicates moderate water ingress. By removing the oil pan for inspection, if water has entered the transmission, the mixture of oil and water will produce a white emulsion that adheres to the oil pan. Mild water ingress: Partial rusting of screws inside the transmission indicates mild water ingress. By disassembling and inspecting the transmission screws, if some screws are found to be rusted after suspected water ingress, it signifies mild water ingress with relatively low water content.
The water ingress severity of Emgrand transmissions is classified into three levels. The mildest case involves minor water ingress, possibly due to splashed droplets during wading or condensation, causing slight oil emulsification and gearshift jerking. Early detection only requires transmission fluid replacement. Moderate cases occur when wading depth approaches chassis level, allowing water seepage through vent holes, leading to increased oil-water mixture and gear surface rusting, necessitating disassembly cleaning and bearing replacement. The most severe scenario involves complete submersion of the transmission during vehicle flooding, resulting in comprehensive rusting of internal metal components, solenoid valve short circuits, and friction plate delamination, typically requiring full assembly replacement. Generally, post-rain gearshift smoothness observation helps assess severity – early anomaly detection and repair prove most cost-effective.
