im wondering while im crusing on drive if its fine to shift to neutral to rev the engine like the manual guys do it while driving for like 2 seconds then back to D?

Except for P and R you can shift to any gear or N, you want, safely. This can be done on any modern day Auto transmission. I've been doing it for yrs. with cars that I have driven up to 175,000 mi. plus. No tranny problems ever. Very

I do it all the time. i pop it N a lot. If I want to just coast along. While backing. When I think about it. I do it a lot. Lol.
Actually on all my cars too.

nice thats good to know!

As long as you have not done the shifter mod your ok.

kharouf

shifter mod? what is that

ptroxx

If you don't know what it is you don't have it. Lololol.

I have no idea either what "the shifter mod" would be unless he is thinking of the mod lots of people do to tie back or disable the solenoid that won't allow you to get out of Park without your foot on the brake. But that mod has no effect on requiring the button to be pushed to go through Park and Reverse. No button is required for S, D, or N. Button is required P to R, R to P, and N to R. No solenoid is ever required except P to R so ...

O.K., gotta ask (and NOT being critical, just wondering), why would you want to do this?

I believe that you could inadvertently shift into reverse if you have done the mod! Could be wrong. I did the mod but would never shift into N on the fly.

In what instance would you need to "rev" the engine? If it is running rough then you may want to get to the root cause.

And I'll repeat, nope. There are two entirely different safety issues. One is you have to press the brake to get out of park. The other is that you don't want to accidently shift to reverse. The former issue is addressed with a solenoid that prevents the shifter from moving out of park if it isn't energized by the BCM computer which has monitored the brake pedal position and seen that it has been depressed off of the neutral position. The other is addressed by a mechanical button latch that prevents going to reverse if it has not been pressed. They are totally independent. The issue some people have addressed by cutting or tying is the solenoid safety. Even with this modification you still have the second safety operating and you have to mechanically push the button to get to reverse. Try it. And, if you press the brake in park you can hear the solenoid click and you can hear it release as soon as you start pulling toward reverse even with your foot firmly on the brake. Once out of park the solenoid people are modifying has never had any effect.

Like the others I have to ask .....Why ......

And I would defer to those that are experts in auto transmisson repair for the answer because I have to believe throwing an auto into neutral at any speed other than stopped has to have some effect.....its not a manual and u are pushing in a clutch to disengage the driveline........

If you were sitting at the top of a hill with your car running (so you have power brakes and steering fully operational) and coast a mile to the bottom of the hill, in neutral, do you think that would damage the engine or transmission? No, it will not, and removing your foot from the accelerator and shifting into neutral to coast will not hurt anything either. BTW, if a manual transmission is in neutral and the clutch is engaged or disengaged you can coast down that same hill.

Dcasole

And your qulifications to make this statement are .....?

We now have lock up torque converters etc that i am pretty sure popping it into neutral and then back into gear just cant be good but ....that is why i asked for someone who has qulifications to answer

And i have to ask the question again ... why would anybody want to in the first place ?

ptroxx

I've been boing it for years mainly when I back up to just coast some into a parking spot.
Or. When I pull into my driveway I do it to. To just coast in. Let the car idle and roll on its own.

How about a qualified GM vette mechanic chime in.

Dcasole

Sometimes I can't believe the questions that are asked here ...
Guys he is not talking about popping it in to neutral and coasting .... which can't be good either [just because you have done it does not mean you are not hurting anything ]

He is talking about popping it out of gear , reving the motor like he has a stick and then popping it back into gear while its rolling ..

All you guys can do what you want but the last trans rebuild on my C5 A4 cost me $2,500 because if a blown seal ..... you do what you want ... I will leave my A6 in gear like it was designed to do ....

I am done with this dumb thread

Many others here like myself cannot confirm how this trans works. Some transmissions have the pump disengaged when not in gear. If you are at speed in neutral, you could burn it up. *in some vehicles. I have no clue if this is the case here or not. It is definitely not like rolling down a hill in manual trans. I can assure you of that.

Again WHY?? I do it at a stop light some time but NEVER when going down the road or down a hill. IMO it is kind of dumb thing to do!
