The automatic 'box is designed to shift gears – leave the brakes to do the stopping. Shifting gear before coming to a stop will cause wear and tear on the transmission band, rather than the brake discs and pads, which are serviceable items.
Not at all, other than the fact that you MIGHT eventually wear out the shifting linkage, or the clutch linkage. With the engine off and the car immobile, there is going to be very little wear and tear on gears or linkages, so I wouldn't worry about hurting anything that way.
If vehicle shifts into gear without having the brake pedal depressed, then BEWARE – your vehicle does not have BTSI in all key positions and could roll away. Most vehicles have BTSI in some positions; but not all. The most common position is the half click forward.
While braking, you should always depress the clutch.
This is one of the most common scenarios wherein people do apply the brakes but forget to disengage the clutch in-turn stalling the car. Well, stalling the car especially with transmission load will take a serious toll on your vehicle's gearbox assembly.
As your speed is already less than the lowest speed of the gear, your car will struggle and stall, when you brake. To avoid this, you would first need to press the clutch so that the engine is not dependent on the transmission and then start braking.
Keeping the clutch pressed down disengages the the gears and the engine from the road wheels, so it's essentially offering far less control. If you continue to do this on a practical driving test, the examiner is likely to fail your test.
To downshift, you should be using the clutch and the brake while you shift gears, rather than the clutch and the gas pedal. Push in the clutch and shift down one gear while pressing on the brake. Let off the clutch slowing to avoid high revs.
You don't have to downshift when you slow down. In fact you can roll to a complete stop with the stick in its highest gear. The real issue is what happens when you want to speed up again. Unless your vehicle has massive power on tap, it won't accelerate from a stop in high gear.
Technically, you are putting additional wear on the throwout bearing if you do not fully release your clutch pedal and allow the clutch to fully engage the flywheel. This includes stopping at an intersection for an extended period of time.
If you engage it while the vehicle is in motion, this tiny lever has to stop the momentum of a moving vehicle, which is a considerable amount of force. Obviously, this causes tremendous stress to the pawl, which can cause it to break or round off, making your park function unpredictable or unusable.

Putting auto transmission in neutral doesn't do anything but force you to shift to drive in order to take off. It doesn't appreciably reduce engine wear or save fuel. Just keep your brake pedal depressed and leave the shifter alone when stopped temporarily.
"Continue slowing down and disengage the clutch just before the engine RPM reaches 1,000 and drop your hand down to the shifter at the same time." Then, you shift into neutral. "After that, you can switch to first just before the car comes to a stop – if you plan to stop and go, like at a stop sign," Gobeil said.
Leave your car in gear at a red light
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. When you put your car in neutral, the clutch is spared unnecessary wear and tear.
To properly engage the parking brake, put your car in neutral before turning it off. Then, engage the brake and put your car in park last. To start your car back up, perform the same operations in reverse.
Downshifting is necessary in order to put the car in the optimal gear to maximize acceleration when the time comes to squeeze on the throttle after we have exited a corner. Contrary to popular belief, downshifting shouldn't be used to slow the car down. That's what the brakes are for.
You can clutchless downshift too but it's a little bit trickier. You need to blip the throttle and press down the shifter right as revs peak and it works best if you're on the brakes since that helps match revs.
Not only will the noise be unbearable, but it's very possible the pawl will break which would require a very expensive repair. Most cars now will prevent you from even attempting to change gear shift but with some old cars, it's possible to do it but will cost you money.
Passing parked cars is a relatively common driving test failure. The reason being that a learner driver may not effectively forward plan is unable to predict a possible situation occurring or does not correctly judge a situation they are currently in.
TIPS OF THE WEEK
This parking is not correct. Pushing directly into the *P* gear puts the stress of the whole car on the *P* locking hole not on the handbrake. If you continue to do this for a long time, this will damage your gearbox.
If you're driving slowly below 10mph and want to stop then press the clutch before the brake so that the car doesn't stall. You're more likely to stall or have a shaky stop if you're driving slowly below 10mph and press the brake first then clutch.
Within the engine at that point, an over-rev condition will occur and internal-engine components will momentarily spin far faster than what they were originally designed to do.
