Elantra HD (2006-10) :: 2007 - Shift Into Neutral While Coasting?
Jul 5, 2011
I'm wondering if it is OK to shift into neutral while coasting (engine on). I've read varying arguments back and forth on whether or not it hurts it. I've done for a while in my 99 suburban and the transmission still shifts just fine. I've tried it once in the elantra just to see how it affects my fuel economy, and it boosts it about 100mpg (coming off a freeway ramp). Braking and steering controls don't seem to be affected by the lower vacuum.
I can see why its not advised while the engine is off (i.e., towing), but if the engine is on, torque converter turning, transmission fluid pumping, I can't see where it would hurt.

I got a new clutch & shift cables & fluid professionally done one year ago. I have only put 5k miles on it since. In the last two months the... gate/slot for 1st & 2nd have been getting worse n worse. All gears show sporadic rough shifting (read rough as a clunk or one tooth grind), but 1st/2nd are consistently rough & the gate seems to be getting narrower...
Environmental & operating temp, do not noticeably affect these symptoms.

My 2005 Hyundai Elantra has 85,000 miles and we are having trouble with the gear shift. It will not shift into 1st from neutral but will shift into 1st from 2nd. We recently replaced the clutch (about 3 months ago). We are about to go on a road trip and are wondering whether we should get it checked out before hand.

Is it bad shifting from drive to neutral then back to drive going 40mph without pressing on the gas only coasting on a daily bases?

The car is an '05 elantra, 97,000 miles, auto., car is new to me. First time on the freeway today, 30 miles @75-85 mph, at the end of the off ramp I could feel it surging, shift to neutral rpm's went to 1500, hoss the gas and back to normal. On the return trip off ramp, went to neutral, jab the gas, everything OK. I'm going to clean the throttle blade, check things, etc.

Vehicle was repaired after front end collision and I get no codes found on scanner, had some bad connectors which I replaced and codes went away. I don't get ready light and the dash lights do not cycle off (ABS, SRS, Check engine, Etc. Etc.) The car will shift into neutral but not drive or reverse. Has new Aux battery and Hybrid battery is showing two bars. What to check ?

I am having difficulty with my Prius, (just started) that it won't shift out of neutral to drive or reverse. I have read several posts, one says replace the shifter knob, but I did read one i thought that said the 12v battery might be the problem with low voltage. The battery is 5 years old.

I have an '07 Prius Touring with about 95K miles that I have owned for about a month (after my previous '07 was totaled). My wife tried to drive it for the first time today, and the problem is that when my wife tries to start the engine, the dash lights come on and the color display comes on, but the car won't "shift" into Drive or Reverse (it will go into Neutral). A dash warning light also comes on that the owner's manual says means Take to the Toyota Dealer for Service. Then if she gets out of the car and then I get into the drivers seat, everything works fine.

My automatic 2007 Nissan Altima has developed an intermittent problem when I go to shift it into park it won't shift down past neutral. I can't physically move the gear shift past neutral and can't take my key out of the car. If I wait awhile or drive off somewhere else it will later allow me to shift normally again and won't happen for awhile. It has happened maybe 8-9 times but I worry it will get worse or break the transmission. I've taken it to a mechanic and they looked at the transmission and didn't see a problem but sense they couldn't recreate the issue they couldn't fix it.

Does coasting in neutral (to save fuel) cause any damage or wear when shifting the gear lever into Drive while moving?

I notice my instantaneous gas millage goes up if I coast in neutral in my new Volvo V50; say when cruising up to stop lights or coming down a hill. I appear to be saving gas, but am I damaging my automatic transmission?

This problem has plagued my '85 Tbird Turbo Coupe for about a month. When I put my car in neutral while moving, the RPMs fall significantly below idle and then the engine usually catches itself and after about 5-10 seconds idles normally. If I do this at high speed (say 40 mph +), the RPMs fall to the point where the engine stalls and dies. If I do it at 25-40 mph, it will go down about 200-500 RPMs and then catch itself. If I do it at 15-20 mph, it will be just barely noticeable, and anything slower than that I can't notice it. It will also do this to some extent when I'm stopped if I rev the engine up really high and let it off, but it is far less noticeable. This car has had extensive work done to it in the past 6 months.
Most recently, I had the fuel injectors replaced, throttle body cleaned, IAC valve cleaned, and the vehicle searched for vacuum leaks. (most of that in search of the solution to this problem as well as to improve the general performance of the vehicle. A week before that, I also had a new fuel tank, fuel pump, and fuel filter installed. I've got a very small leak on the back of my muffler, no cat, and no other exhaust leaks I can find. I am getting a lot of black carbon out of the exhaust, but I have been running some fuel system cleaner through it. Also, the car sat for like 8 years before I got it, and the original cat became clogged and really gunked stuff up. I had all of the upper engine gaskets replaced, as much as we could get to cleaned internally, and the cat cut off at that point. Timing is very close to 10btdc. Could be 9.5, but just about right there. I double checked, no vacuum leaks that I could find with a can of carb cleaner. I tried checking for codes, but it's not even throwing me a confirmation code or anything, which is odd. But, my connector was pretty gummed up (I did clean it as good as I could) and just about anything wiring is suspect. I used two engine code readers that had previously been used on the car. Other than this, the car has plenty of power and runs fine down the road.
Here's the master list of what I've replaced in the past 6mo:
FUEL SYSTEM Fuel Pump (twice) Fuel Pressure Regulator Fuel Tank Fuel Injectors
ASSORTED FILTERS Fuel Filter (twice) Air Filter Oil Filter (several times) Oil Filler Cap PCV Valve
HOSES/COOLANT SYSTEM Nearly every Vacuum Hose Every Coolant Hose Heater Core (twice)
SENSORS AND COMPUTER STUFF Engine Control Module (ECM) Vane Air Meter (VAM) Idle Air Control Valve (IAC) Oxygen Sensor
STARTING SYSTEM/ELECTRIC/Misc. Spark Plugs and Wires (Motorcraft) Starter Solenoid Coil Pack Distributor
TFI Module Distributor Cap and Rotor Battery Timing Belt
EEC Relay Ignition Switch Tires Front Brakes Brake Master Cylinder (had previously been damaged) Front tie-bars Every gasket from the head up.

So I was driving my car about a week ago when it decided to "die" on me for about 2 seconds. I was coasting in neutral (tiptronic) to a red light when the car's engine light popped on and the car just bogged down hard. I threw the car into drive and the problem went away immediately. I haven't had the problem since then, but I'm also not allowing the car to coast in neutral anymore.
I was thinking about bringing the car in to have them read the computer but is this something that they would be able to trace back or would I be out the 90 bucks for nothing? I have absolutely no clue what this could be.

I have a 2007 Elantra with 138,000 miles. I never had any slipping or jerking or reverse issues in the past. I got into the car put it in reverse just fine then put it in drive and nothing happened, I put it in park and the car kept rolling like in neutral and started making a loud grinding noise. When I put the transmission in any other gear the noise stops but will not move and acts as if in neutral.

Car has 67k. It did this before when the car was under 50k. took it in , got it documented and they could find nothing. Last 3 days when I punch on the freeway to pass someone, the car goes in to neutral. Manually down shifting does not work. I had to pull to the side of the freeway today for a few minutes before it would engage. Felt like I was in a very dangerous situation.

I got a brand new 2014 prius c(one) about two weeks ago now and it feels like it "hard shifts" when coasting from 43mph-40mph. The dealership says its normal, they said that it is just the engine switching.

I have owned my 2008 Elantra for 8 months. I am the second owner and the car has 75K highway miles. I would like to know what the RPM is supposed to be at WOT (getting onto highway).
I have seen it go to almost 7K before shifting. That does not seem normal as redline is 6.5k The trans fluid was changed (by me) with the correct, recommended fluid at 60K. That did not change the characteristics of the high shift points at all. It seems to be just fine with normal city driving, very smooth. A great car overall and I don't want to screw it up as I drive on the highway every day and need WOT to get into 80 MPH traffic.

I'm having with my 2008 Elantra. In short, the car stalls when I'm at a stop, and then for a period of time, I cannot get the car in park or turn it off. When I am eventually able to get it to do so, I turn it back on, and it restarts like nothing ever happened. The full details are below. The dealership is clueless, and I am so upset/frustrated.
Three weeks ago, I was slowed down at a yield sign, and when I tried to inch forward, my car stalled. The radio, AC, etc. were all still on, but I could not move forward. I noticed the EPS light on on my dash. I also could not turn the wheel or shift the car into park (could only get it into neutral), and therefore, could not turn off the car/get the key out.
After cops pushed me into a parking lot, the car sat for a bit (still technically "on"). Eventually, a friend got in and forced the wheel to move a bit in each direction, and was able to put the car in park and turn it off. When we turned it back on, the engine started and everything appeared fine. I canceled the tow and drove it home.
I took the car to where I bought it and was told there was a technical service bulletin related to the powertrain control module, and they recommended I take it to the dealership to be fixed. The first Hyundai dealership I took it to said they addressed the TSB, and also recommended I clean out the fuel line as that may have been affecting it ($150). Because it had been awhile since I'd done anything like that and the work was relatively in expensive, I said sure, got my car back and went back to my life...
Fast forward to this week. I'm driving in rush hour traffic, and the SAME THING happens again. I immediately tried to move the wheel around to get the car in park and restart, to no avail. I called a tow. After some time passed, the same thing happened again -- we were able to get the car in park, turned it off, turned it back on and it seemed normal again.
I had the car towed to another Hyundai dealership, explained the situation and they tested and drove it around a bit over two days, but because they are unable to recreate the issue and no codes appear, they can't do anything for me.

I drive a 2008 Elantra and had a mouse chew the wiring harness from the output speed sensor on the transmission to where the wires diverge from the Engine harness. It was still able to drive but the transmission stayed in third gear, the cruise set light stayed on and the check engine light came on.
I had noticed sluggish shifting before this happened and assumed the speed sensors needed replaced so I purchased the input and output sensors (42620-39200 & 42621-39200) and that is when I noticed the wires missing. I've checked the harness for other potential mouse foolery, took the old connector to the output sensor soldered wires to it and reconnected them to the engine harness. On a test drive after rewiring and replacing the sensors the car still stays in third and the set light is still on however the check engine light is not on anymore. At this point I'm clueless what to do next besides drive it to a dealer.

2010 Elantra. The other day I noticed that while driving with cruise control on, on the way home from work, pressing the brake pedal didn't turn the cruise control off. I felt the brake work, but the engine started revving like I was holding down the accelerator so I took my foot off and manually turned the cruise control off with the On/Off button. I didn't think much of it at the time other than it hadn't done that previously. Then, when I got home I couldn't put the car in park. The shifter wouldn't move past Neutral up to the Reverse or Park position. Using the shift-lock release push button I was able to put it in park. I'm not sure if the two issues presented here are related, but they both occurred for the first time on the same day. I was hoping it was a random occurrence and it would be better today, but things haven't changed. The brake and accelerator have continued to work just as before and the car feels no different driving it.

Noticed this in the last couple of weeks. On light throttle acceleration the 1-2 shift seems perfectly normal, but 2-3 occurs rather sooner than previously, and 3-4 seems to go through neutral (tach climbs maybe 250-500 rpm for maybe a second or so) rather than a solid shift. Getting on the freeway (WOT), seems normal, and other than light throttle if there's a problem with shift points, I don't notice it.
Maybe an issue with relearn/reprogram? Car is low mileage, adult driven, 16,721 miles of easy highway and local driving.
