CAR TRANSMISSION!!! Omg i have a question about transmissions in cars. specifically, with neutral, park, and?

Question

Okk. So in cars right, you know how when you first put it in drive, and without even touching the gas petal it goes slowly moves forward? I dont know if it does this to everyone but in my ford expedition it does, anyways:
SO, 1: when you put it in neutral does the axel that the pistons in the motor turn disconnect from the power train wheel thing?
2: When you put it in park, does the car also go to Neutral? (so basically would it be safe to accelerate when in park or would it grind geers and stuff)

now, back to when you are in drive, and the car movies forwards without touching the accelerator -- if you step on the brakes and stop the car, but keep it in drive, does the car automatically disconnect the motor axel to the wheel power axell?? Because if you are in drive, and the motor is trying to turn the wheels, but you keep the wheels on brakes, wouldn't geers grind or something get jammed or something because its trying to spin the axel but it can't because the brakes stop it?

you know STONECOAST420............... IIIIIIIIII am looking for and expecting SERIOUS and accurate answers to my question on the transmission of my car........okay so i don't appreciate your blanderashing okay

Answer 1

OMG! I hope you don't have a license!

At first I thought this question was boring and stupid, so I couldn't figure out why you opened it with "CAR TRANSMISSION!!! Omg"

But on further reflection, I realize that this question is actually very exciting. So exciting in fact, that I think you should have capitalized OMG, and probably gone with OMFG with some more exclamation points after the OMFG.

Answer 2

If your car has an automatic transmission, the connection between the engine and the transmission is called a "Fluid coupling", the fact being there is a turbine-like wheel fixed to the engine/ crankshaft, with fins on it. This turns with the engine crankshaft.
In a part called a fluid coupling, or a torque converter, is another part like the first one. This is connected to the transmission and the driveshaft/ rear differential/ rear wheels.
When you put the car in drive, this allows the front half to turn the rear half of the torque converter, thus also turning the driveshaft and on back to the rear wheels.
The connection between the front half and the rear half is oil, or transmission fluid.
The turning engine spins the front half of the converter, only, until you put the car in "Drive" or "Reverse". Thru various means, the spinning fluid then is sent thru various channels, to make the car move. And yes, the car might move forward when in "drive" and the brakes off. You should always keep your foot on the brake pedal when shifting out of neutral, so you have control!
Stopping the cars movement with the transmission in either forward, or reverse, will not harm anything! Thats the way it is supposed to work! There are no gears to "Grind"!
The differential works like it always has-to make the car move, but it has no gears to shift, except in large trucks where they have a 2 speed differential, although i do believe those are on the way out.

Answer 3

1. The transmission is not in gear, the transmission is inbetween your engine and rearend that have the axels your wheels are bolted too.

2. Yes park is like neutral, the transmission is not in gear, you can rev up the engine and the trans will be okay.

No the car will not automatically disengage from the axel, the transmission uses what is called a torque convertor.... it is big and round is filled with transmission fluid, it works like a big centrifical clutch, when you rev up the engine the torque convertor grabs and turns the transmission, which turns your wheels. Whe you are in drive the engin is rotating with the torque convertor, but the transmission is sitting still..... it is fine..... nothing bad happens at this point, next you step on the gas, the torque convertor grabs, tirns the transmission which turns your wheels and off you go... :)

Answer 4

When the car is in drive, with an automatic tranny, it is normal for a car to creep forward when the brake is released due to engine idle speed. When in park, no damage to the tranny will occur if you rev the engine. When in neutral, tranny gears are disconnected and car will not move if engine is accelerated. Tranny or drive train do not disconnect when brakes are applied while in drive and gears will not grind because tranny uses hydraulic principles to drive auto.

Answer 5

perhaps you should not even be driving!
