What causes an automatic transmission to shift?
Worn fluid can lead to hard shifts When your vehicle’s computer tells the transmission to shift gears, hydraulic pressure (provided by the fluid) squeezes a series of plates together inside a clutch pack to connect the engine to the transmission output shaft and route power to the wheels.
Can too much transmission fluid cause hard shifting?

So you’re not really causing any extra wear and tear.
How do you go from 1st to 2nd smoothly?

Does Quickshifter hurt gearbox?
QUESTION: Do quickshifters have a negative effect on gearbox life? ANSWER: Anyone with gearbox-service experience knows that the dogs that engage on the first-to-second upshift get the worst hammering. … A quickshifter, because it cuts the ignition, is less damaging than clutchless upshifts.
Do you let off the gas when shifting?

Does Double clutching hurt your transmission?
