Though it will not harm your transmission to shift into Neutral while your vehicle is in motion, the additional wear on your brakes by leaving the transmission in Drive will be negligible over the life of the brake pads.
It is that minor.
NEVER, EVER go into neutral while slowing down to a stop, for 3 reasons: 1.
Is manually shifting an automatic bad?
Shifting too quickly while your car is still in motion can cause significant damage in the transmission because there is a spinning coupling mechanism that can prematurely fail if it becomes worn from the harsh gear change. Always come to a complete stop before shifting into another gear.
What happens if you shift into reverse while driving a manual?
“If the transmission was not designed with a reverse inhibit feature, engaging reverse while driving forward will, most likely, stall the engine,” Renneker said. “The car won’t lock-up or skid, but it will slow down a bit and act like the transmission is in neutral.”
Should I put my automatic in neutral at traffic lights?
When you’re stopped in traffic:
If you’re stopped in traffic or at a red light, it is a good habit to switch to neutral until the light goes green. Many people will argue that switching to neutral all the time can wear on your transmission. Tip: DO NOT shift into ‘P’ or ‘Park’ when stopped in traffic.
Should you be in neutral at traffic lights?
Admit it – if you’re stopped at traffic lights, do you wait with the clutch down, first gear engaged and your foot on the brake? As well as wearing out your leg muscles, you’re also putting needless strain on the clutch. It’s much better to put your car in neutral and apply the handbrake to keep it stationary.
