* Mechanical Damage: Automatic transmissions are designed to shift gears while the car is at a near standstill. Shifting while moving puts immense stress on the transmission's internal components (like gears, clutches, and bands). This can lead to:
* Broken gears: The gears might grind or break due to the sudden load.
* Slipping clutches: The clutches might fail to engage properly due to excessive wear.
* Damaged bands: The bands that control the transmission might stretch or break.
* Loss of Control: Shifting while moving can cause the car to lurch or jerk unexpectedly, making it difficult to control. This can lead to accidents.
* Internal Fluid Contamination: The sudden pressure changes can cause the transmission fluid to overheat and become contaminated with metal shavings, further damaging the transmission.
Always bring the car to a complete stop before shifting into Drive or Reverse.
If you experience problems with your transmission, it's crucial to consult a qualified mechanic for diagnosis and repair. Never attempt to fix a transmission issue yourself.
