100 thoughts on “5 Things You Should Never Do In An Automatic Transmission Vehicle

  1. As a teenager I drove my moms 5.0 Mustang GT a lot and I would take it to my High School Parking lot at night with my buddies and we would neutral drop that thing and launch it, do burn outs, you name it. Rev it up to red line and slam it into drive. Yea never realized how bad that was for the tranny and luckily it held up. My mom ended up crashing the stang years after I graduated from high school and moved out and it still had the Original Automatic Transmission.

  2. Very Interesting ! Most usefull hint for ordinary drivers is nr4, on 7:15 , I agree. Still , newbie vintage cars collectors when acquire 51 Buicks or Chevys with Dynaflow or Powerglide, start with "L" even on flat streets to "help" the motors, what I think is wrong, incurring on what you said above. I have two friends who do that. Thanks Jason for your very clear and didactical video,

  3. Can you do one for towing with an automatic transmission? Is  it better to be in drive or 3rd gear when towing a load and do trailer brakes help save the transmission?

  4. Thanks for the effort you put in on this video. I’m uk and not everyone would understand this let alone understand a manual car. Automatic transmissions are a thing of beauty these days and should be understood. Tough to get a lux car without one and in uk a lot of drivers don’t get the transition or nuances. Great video and top effort.

  5. I had a Lincoln whose data center allowed instantaneous Now fuel mpg. I used to speed up just before a hill put auto trans in neutral and view just how high my instantaneous fuel miles per gallon would get. Highest I ever got it was in the 70's mpg. Does this mean I will be visited by the Coasting Police? It was over 10 years ago; Texas has a 6 year Staute of Limitations…guess Im safe.
    Edit: Confession Time
    I also run thru the house w/scissors in my hands; Doh, are the Scissor Police on their way now?
    Edit: Confession Feels Good
    I also ripped the tag off my mattress…no reason, I just felt like it: the rush of addrenaline was off the charts. Are the Mattress Police on their way also. What can I say Im a rebel w/out a cause, a bad seed. Are there any 12 step programs for someone like me?

  6. He goes on in another video and says when you’re stopping for a long time put it in neutral because your car’s transmission is in stress well I call BS on his channel he says things and contradicts them a lot

  7. Now, I know to stop the car with the brakes, but I pull out of driveway backing up a hill, is it still bad to shift into neutral, let the car stop, and then start rolling forward and then put it in drive while rolling forward? I feel like it's less stress on the Transmission. @Engineering Explained I hope you see this, i've been meaning to ask this for a while.

  8. The corollary to the last point (should have been the main point) is that you should always use the parking brake when parked – using the parking pawl alone (especially on even the slightest hill) to keep the car from moving puts unnecessary strain on the transmission

  9. Me and my buddy used to 'hyper-mile' in his old 1990 Vanagon. "Slip it into neutch" we called it. We also shut off the engine to maximize economy. I have no idea why the cooling system kept springing leaks in various locations 😀 😀 😀

  10. Bit late question, but was told to use the hand brake after parking the car and turning it off so the car is not resting on the transmission

  11. I always drove manual cars but my 08 get unfortunately is auto. So my question is. Can I switch to manual mode while driving or do I have to be at a dead stop?

  12. good day,i'm danny from the philippines,i would like to ask why i can't put to PARK the automatic transmission of my 2013 Chevrolet ? the car is okey,in fact i use it everyday,it runs forward when i put it to Drive, it backs up when i put to Reverse, it just would not engage to Park, i am now using the manual parking brake whenever i park the car, is there something wrong with the transmission?…

  13. One reason I like to put my auto in neutral is that the pulling at the stop light annoys me. I've always driven manuals so I'm not used to the pulling effect. I also want to preserve my brake lights by not holding them on for a minute. What do you think about these reasons?

  14. When my car is idle feels like engine is shaking like when I stop for red light and if keep it on D the car mildly shakes but if i put it in N its quite again. Any idea why??


  16. Im driving my car, my speed is about 100km/h, then i switch to "R" because i thought it is for "Rocket" hahahaha lol



  18. I had to use park to stop once… On a cold morning I was about to leave the gated apartment complex. When I was nearing the closed gate (where you have to stop) suddenly the brakes wouldn’t do anything . So I quickly pulled the handbrake and put the car in park out of desperation 😬

    Somehow afterwards the brakes worked just fine…

  19. That's not how torque converters work m8. The outer shells are welded together, THEY reverse the flow of fluid TO the stator thus spinning it which is connected to the input shaft and the trans pump which generates the hydraulic pressures needed to engage the various bands and clutches.

  20. The best is when people go to McDonald's drive through and shut off their engines to save gas but refuse to walk their fat asses inside.

  21. I'm no engineer, but please enlighten me as to the correct procedure when approaching a RED. At the moment, I step off the gas, go to neutral, and then when stationary engage Park. Is this or is this not the optimal approach?

  22. Sir drive CVT automatic transmission car can I apply neutral gear when I am at traffic signal when it is red please reply sir

  23. that 4 one made me wonder, why is there a parking mode at all? logically manual vehicles don't have it and they just put it on neutral and use the hand brake, so why do automatic cars have it if you can select neutral and apply the handbrake the same way as with manual cars?

  24. Never let your automatic car run down a hill in neutral to jump start it … when you pick up enough speed and slam it into gear the car is broken 😎😎😎 and your battery is still dead

  25. When I'm driving on the freeway and I wanted to go faster FAST, I would step off my gas and shift to D3 from D (Honda Civic 2012 coupe), will that damage the transmission if I do that then GAS it??

  26. I have a 2003 Corolla with 280000 miles on it. I always put it neutral going down hills. Only had to change the brake pads once. Never had a transmission problem. I live on dirt roads.

  27. God forbid the owner's manual made it that easy. Gave me 4 sets of instructions. Tried each one. No go.
    Thanks for the video.

  28. Is it okay for an automatic DCT to engine brake? Lets say im going downhill and i put it in 2nd gear. Will it damage/prematurely wear anything?

  29. I drive a 2017 Ford Mondeo (Fusion) with automatic gearbox. When I have to stop for a short period (red lights, traffic jams) I leave the transmission in D and pull the electronic handbrake on. The handbrake then automatically disengages when accelerating, very handy…. If I park the car on a slight incline does it suffice to leave the transmission in D or do I always need to apply the handbrake ?

  30. I had my brakes go out on a vehicle while I was driving in Germany. Trust me, using the hand brake to stop the vehicle doesn't make for a very smooth stop. It just locked up the tires and I went sliding for a very long distance… and I wasn't going but maybe 35 mph. I didn't just yank the thing either… I pulled up on it nice and slow. And like the diagram shows, it's all or nothing pretty much. Went from no braking to full on locked up wheels. It was an old vehicle but I suspect modern ones would do the same thing. It stopped me, but I slid at least 3 or 4 times further than had I used no skidding normal braking. It was rather scary.

  31. Hi. I have a 2004 chevy Corvette. I have it with a 4 speed automatic transmission. I like to manually shift it. Like I always put it in 1 and
    Go back and forth between 1-3 as a would drive a stick shift, and use D for highways. Will this hurt the car when manually shift it all the time? Thank you. Best Regards Lasse.

  32. 1. Your argument about fuel economy is flawed. Yes, the engine burns more fuel in idle, but most automatics have a free-wheeling clutch so it's idling down the hill anyways. If you're in tow mode or downshifted so you're no longer freewheeling, you're slowing the car down via intake vacuum to keep the engine turning, which robs you of speed at the bottom of the hill. You then have to speed up by the amount you lost, which likely requires more fuel than you saved by not idling down the hill.

    2 and 3. The clutches inside the transmission have to slip while changing gears all the time. Occasionally putting extra wear on them isn't going to have noticeable effects on longevity. At least on some cars, neutral dropping gives much better launch performance than stalling the torque converter. So if your goal is speed, that's what you're going to do regardless of extra wear.

    4. I put automatics into neutral while stopped because it's much easier to slightly hold the brake to keep from rolling than moderately holding the brake to keep the engine at bay. Some transmissions won't even move until you give it throttle, while others require a lot of brake pressure to hold still, so this is context-dependent.

    5. Probably good advice, but generally the pin is just going to rat-tat-tat like accidentally shoving a manual towards reverse instead of fifth when they put reverse where seventh would be. It shouldn't damage anything, especially at low speeds where there's not that much pressure to begin with (that pin is designed to hold the car's weight on a steep hill). That said, I did hear a story (second-hand) about a guy who shoved it into park at like 40 mph and it exploded his transmission all over the highway, so that might be an issue. And it's uncomfortably shocking for passengers when the transmission stops the car instantaneously from 3 mph.

  33. What will happen if the gear is moved to reverse when the vehicle is on the road with the speed of 100 miles per hour??

  34. Hi, how bad is it if I accidentally put the car in Neutral while driving and then put it back in Drive again while going about 25-30mph ? I heard a slight "thud" sound .. nothing crazy but it bugs me!

  35. I was about to park my SUV and I accidentally put my gear to drive instead of park. Is that bad? How will it affect transmission?

  36. Best way to brake downhill is to spin the car 180 so you are reversing at 100 kmh+ then put it at 5k rpm+ it and dump into 2nd this way you wheelspin in the opposing direction for max force in the opposite direction. Eventually the tyres will burst for max grip. I would say 1st gear but. I am unsure with thinner tyres that the wheel speed is fast enough.

  37. I have an example where you might want to put the transmission in park while moving. Two, actually. The first one, I picked up my truck from the mechanic, started driving home and the throttle stuck wide open. I couldn't switch the key to the off position when it was in gear, so jammed the brakes on hard and came to pretty close to a stop then switched to park ( easier to find than neutral) and turned off the ignition before the rpm ran away. So just sort of, not really.
    The one that was a perfect example, driving a loaded truck down a steep grade and the brakes failed completely, not fade, just completely gone. Master cylinder I think. So with the transmission in reverse apply throttle to slow the descent, if the engine stalls slam it in park before it picks up speed. Gravel roads so if it's too much torque it slips the wheels a bit. Also in the middle of nowhere, so no mechanics, no parts, no tools, no communications, you have to get it done or walk. Similar situation when a fuel pump stopped working, used some insulator from electrical conduit, pulled the conductors out and used the tube to siphon from a small can of gas on the roof directly into the carb.

  38. Jace Henderson  breaking while in neutral is not efficient u are only uaing brakes at that time, but breaking while in gear either auto or manual is efficient as your engine is also helping to slow down
    jut try to stop a car without using brakes in gear and in nutral ur car will stop sooner as compared to that in nuetral, REMEMBER THAT EVERY SECOND IS IMPORTANT

  39. Never shift into reverse on the highway…… Not even with a rental, in Florida, on spring break, with your drunk buddies……

    How does your car work with all those parts missing……..

  40. Now is 2019 and many cars coast in neutral at motorway speeds to save fuel. Even the new 911 does it. Less RPM means less fuel loss, if you are not using any fuel it doesn’t necessary mean that you are going more efficient.

  41. I have one possible good reason to be in neutral in a stop. I'll leave it up to you to agree or disagree. Years back I was rear ended in a manual car and the impact knocked me out for a few seconds. I was lucky the car stalled because had it been a automatic I would have rolled into a on coming dump truck at high speed which would have obliterated me. While a automatic Is going to role in a impact situation like that described above, and chances are in that particular situation I would have still be obliterated, in many situations if you are hit, knocked out, the car is only going to roll a little bit vs being knocked out with a car in drive which will continue to drive itself at slow speeds until it hits something else to stop. I know this isn't the greatest example of why to put a car in neutral for stops in traffic but being in that situation once being knocked out, I feel better being in neutral for most long traffic stops.

  42. Well, this video was kind of useless, unless you only have a 2 digit IQ. The upside is, while he was droning on, a bunch of the comments are brilliant. THAT made this video worthwhile. Well done. 🙂

  43. When I stop at a light I always leave my car in drive. But maybe if I put it in Parking, not in Neutral, I can maybe prevent a dangerous situation. Suppose I'm the first car at the light, and someone bumps me on the back. I get a very hard hit and my foot slips away from the break. If I'm in Drive or Neutral my car will move forward and can be hit by another car coming from the cross road, Instead if my car is in Park, from what you explained a locking pin is blocking my transmission, I'll ruin the pawl, but at least I wont cause another accident. It's the same principle that applies to manual transmission car, when they suggest you when you come to a stop at a light, always put your car in first gear and hold the clutch down, So in case someone hits you from the back, by releasing all the pedals, the car will stop and will not get in the middle of the intersection.

  44. I ALWAYS put the car in neutral at a light. LEXUS says that at idle in drive the engine is at 700rpm and is subject to strain on the cam drive belt because of the normal crank imbalance. If you put it in neutral the extra 200 rpm will stop the out of balance vibration and the belt will last longer. ALSO – It cuts down on engine heat.

  45. Hey cool video. I have a question specific to the F Sport as I just bought an IS. Is it safe for the trans to switch between modes with the dial? Like from Eco to Sports mode. Thanks!

  46. Anyone from Colorado's front range knows that east-bound I-70 approaching 470 is valid reason to require a vehicle be kept in gear when in motion.
