i drive a CVT lancer and while i drive on the highway, i usually just switch my car into Neutral so it just coasts on the highway. sometimes i switch my car to Neutral when i go down the hill so i dont have to use gas. i was wondering if this is bad for the car? i dont think it is, but i was told by a friend that it could damage the tranny.

give me ur input about this

thanks in advance

 

I do not know a lot about cars but I would think it wouldn't be that bad to pop it into neutral, but really bad for the tranny if u neutral drop it into a gear, the CVT is very delicate and cannot handle stress like that

Anyone, please correct me if I'm wrong

 

Yeah, it's the transition from N to D or whatever that I'd be concerned about... Do these CVT trannys lurch or anything when you transition from N to D?

 

well if i switch from D to N and coast till i get to a red light, i put it back in drive and u could feel it shake a bit. when i switch from D to N and coast on the highway and switch back into D i dont feel any crazy movement.

 

^Interesting...kind of the opposite of what I would have expected. I couldn't expect much of a change in MPG with this driving style; only thing that I'd be worried about is the tranny in this situation.

 

Yeah saving yourself a few dollars at the pump isnt worth the risk of destroying a transmission 90k miles early than it should have been destroyed

 

I would double check to see if cvt during decel mode engages the wheels or not... if it doesn't then your not doing yourself any favors.

As other have said.. you might be shocking the tranny by going from neutral to drive...And in all honesty I think the new generations of CVT are so dam refined that I don't even think its necessary to put a car in neutral

 

The CVT engine breaks if you let off of the gas so coasting is basically impossible unless you use neut, thats why hes asking this, there is no roll factor. you have to constantly apply pressure to the pedal to go forward. but so long as you arent reving the car before putting it into drive, it should be fine. Only thing to expect is your tranny to instantly slow your car down once you pop it into drive i would guess.

And hello to my neighbor in weston

 

I just read in the USA Today I think that the new Impala with cylinder deactivation only gets 1 MPG better than w/o it. So if you really think you'll be saving gas, probably nothing noticeable. Save the tranny too!

 

It's illegal to pop it into neutral like that, FWIW.

Just put it in 6th for the downhills if you're that worried about the MPG.

 

If you are on the highway do you not use cruise control?

 

you actually waste more gas by having it in neutral than by keeping it in gear. when its in neutral, it has to burn fuel to keep the engine running as opposed to the wheels rotating and keeping the engine running.

when the you are in gear, and not on the throttle, and the car is rolling, you are using absoutely no fuel.

 

not like you're saving that much gas anyway

 

This was going to be my point. I honestly think this is a waste. I beleive you are damaging the CVT by disengaging it under load. As Black Sheep said carry it into Sports mode and Paddle up to 6th Gear.

 

so youd rather waste gas when its not necessary? it is also illegal in most states to coast in neutral.
