What Causes the D Gear Not to Move While the R Gear Functions Normally?
1 Answers
When the D gear does not move while the R gear functions normally, it is typically due to issues with the forward gear or a malfunction in the solenoid valve that controls the forward gear signal. Below are the possible causes: 1. Forward Gear Teeth Damage: This occurs when two metal gears collide harshly, accelerating wear on the gear teeth. Solution: A major transmission overhaul is required. 2. Faulty Forward Gear Signal Solenoid Valve: You may notice difficulty in starting the car. Even when pressing the accelerator, there is no noticeable increase in speed. Solution: Visit a professional repair shop promptly for inspection and to add transmission fluid, ensuring better lubrication for the transmission gears.
