Paddle shifters do not require lifting the throttle. Installing paddle shifters on a family car essentially adds a manual mode to the automatic transmission, allowing gear changes without taking your hands off the steering wheel. This makes driving smoother and quicker while adding a bit of fun, so there's no need to hesitate when shifting—you can use the paddles even while pressing the throttle. Typically, the left paddle is for downshifting and the right for upshifting, though some models use a single action (pulling or pressing both paddles) for shifting. To use paddle shifters, simply shift the gear lever to D, S, or manual mode, then switch to the appropriate gear via the paddles once the engine reaches the optimal RPM.

I've been driving an automatic transmission car with paddle shifters for several years, and from my personal experience, you don't need to completely lift off the throttle. During aggressive driving, directly downshifting with the paddles while maintaining throttle actually makes the transition smoother, as the engine automatically blips the throttle to match revs. Especially when overtaking on the highway, keeping the right foot steady on the throttle and downshifting with the left hand brings immediate power. However, for smooth daily driving, slightly easing off the throttle before shifting feels more comfortable, otherwise it might cause jerking. The key is to understand the vehicle's tuning—some performance cars shift faster without lifting the throttle. For cars with modified ECU programs, it's especially important to first test your car's response characteristics.

As an experienced driver, I recommend beginners to slightly lift off the throttle when using paddle shifters. Although the vehicle's computer can help match the RPM, releasing the throttle before shifting has two benefits: first, it reduces transmission shock, which is better for the clutch plates in the long run; second, it allows for better control of power delivery, avoiding abrupt acceleration. However, many new cars now have very intelligent electronic systems. When I drove my friend's new sports sedan, shifting without lifting the throttle was still very smooth. The key is driving habits—if you want convenience, just operate directly; if you want precision, coordinate with the throttle. On the track, it's a different story—there, you need to maintain full throttle opening.

Manual transmission drivers know to ease off the throttle when shifting, but paddle shifters in automatics are different. Many models allow paddle operation without lifting the throttle - the ECU automatically coordinates throttle and transmission. Here's how I overtake on expressways: keep the throttle halfway depressed, tap the downshift paddle, and instantly get an RPM surge with that satisfying kick-in-the-back acceleration. Of course, older models may lack this intelligence, so easing off the throttle is advisable there. Note that frequent paddle shifts during sudden acceleration put extra stress on the transmission - no need for such antics in daily driving.

My driving habit is: for slight acceleration, I directly use the paddle shifters without lifting the throttle, such as accelerating from 60 km/h to 80 km/h in the city. For hard acceleration with heavy throttle, I slightly lift the throttle before downshifting to avoid jerking. In fact, modern cars with paddle shifters have protection programs, so not lifting the throttle won’t damage the transmission, but tuning varies greatly between brands. European cars are usually more aggressive, while Japanese cars tend to be more conservative. It’s best to check your car’s manual—some sport mode instructions explicitly state that lifting the throttle isn’t necessary. The key is to avoid repeatedly using the paddles in the redline zone, as that can genuinely harm the car.

From a mechanical perspective, whether to lift off the throttle during paddle shifting depends on the transmission type. Traditional automatic transmissions with torque converters can buffer the shift, so keeping the throttle open is generally fine; for dual-clutch transmissions, it's better to coordinate with throttle input to reduce clutch wear. Having driven over a dozen paddle-shift-equipped cars, I've found that turbocharged cars shift more smoothly without lifting off the throttle, while naturally aspirated engines prefer a slight throttle lift for smoother shifts. Modified car enthusiasts should take special note – for tuned vehicles, it's advisable to lift off the throttle during shifts to protect hardware. For daily driving, don't overthink it – do what feels natural, as cars aren't that fragile.
