The consequences of switching a Volvo automatic transmission on the move depend on the specific action:
Shifting from Park (P) to any gear:
*If the engine is running, it may cause damage to the transmission.
* It is usually safe to operate with the engine off.
Shifting to neutral (N) while driving:
* May interfere with safety systems such as ABS and ESP.
* May cause increased fuel consumption and transmission wear.
Shifting between gears (P, R, D, N):
* Generally safe provided the vehicle is in motion and shifts smoothly.
* However, sudden shifting may damage the transmission.
Shifting from reverse gear (R) to any other:
* You should come to a complete stop before shifting to avoid damaging the transmission.
Shifting from Neutral (N) to Gear:
* May cause jerking if the vehicle is in motion.
* May cause damage to transmission if shifting is performed too harshly.
Other consequences:
*Overheating: Shifting gears on the fly can place additional stress on the transmission, which can cause it to overheat.
* Clutch damage: In automatic transmissions with a torque converter, sudden shifting can damage the clutch.
* Wear of mechanical components: Improper shifting can cause wear on the gears, shafts and bearings in the transmission.
*Reduced fuel efficiency: Irregular shifting of gears can reduce fuel efficiency.
* Collision Hazard: Shifting gears at the wrong time can cause you to lose control of your vehicle, increasing the risk of a collision.
Correct gear shifting practice:
*Always shift gears smoothly.
* Stop completely before shifting into reverse gear.
* Avoid shifting into neutral while driving whenever possible.
*Refer to your vehicle’s owner’s manual for specific shifting instructions.
