Why Can't the Car Suddenly Reverse?
1 Answers
Automatic transmission cars failing to reverse can generally be attributed to transmission issues. When the reverse gear is engaged and the indicator light is on, it indicates that the transmission's wet clutch has supplied hydraulic oil, and the light only illuminates under pressure. Hydraulic transmission (automatic) transmissions are simpler to inspect and repair compared to mechanical (manual) transmissions, but due to their simpler structure, inspections require meticulous attention. Often, overlooking a seemingly minor issue can lead to rework. Below is an analysis of potential fault causes: 1. The transmission's wet clutch friction plates are stuck in the spline groove. 2. The reverse clutch oil drain valve fails to seal properly. 3. Wear and tear on the transmission's reverse wet clutch spline.
