5 Things You Need to Avoid in Automatic Transmission Vehicles

Automatic tranmission 3

Automatic transmission cars are easy to drive. Though the mechanism involved in an automatic transmission is complex. Due to their complexity, automatic transmissions are expensive to repair. In order to maintain a vehicle with an automatic transmission gearbox, here are a few things you shouldn’t do in an automatic transmission vehicle.

Do not Use “Park” as a Brake:

Never put your car on “P” while the car is moving. The locking mechanism which is a pin, prevents the car from moving when it’s in “Park”. The Pin is called a Park Pawl. The Park Pawl acts as a lock in between the gears. This pin stops the gears from rotating, which prevents the car from moving. Therefore suddenly shifting the gear to “Park” risks damaging the park mechanism.

Shifting the Gear to Park or Neutral at a Stop Signal:

This is debateable, many believe that they relieve the gears from unnecessary stress when they change the gear to park at a stop signal. An idle car in drive mode causes much less stress to the transmission. When you have the brakes pressed and the car is on drive mode, the engine is constantly rotating and the impeller connected to the engine is trying to rotate the turbine to gain speed (but the wheels are stopped by the brake). The amount of stress applied to the transmission when the car is in neutral is very low, when compared to the stress applied on the drive mode. People also believe that they save fuel by changing to neutral from drive. The amount of fuel saved is very low and it really isn’t worth the trouble.

Shifting to Neutral when Going Down a Hill:

Putting the car on neutral while the car is moving downhill is not recommended at all. This is because when the car is in neutral, you have no control over the speed at which, the car is travelling. A lot of people believe that they are saving fuel when the car is descending in neutral, this however isn’t the case. Most modern automatic transmission systems cut the fuel supply of the car while the car is moving downhill.

Do not Rev the Car to Launch it:

Revving the engine in neutral and shifting it to drive to launch it can damage the automatic transmission. An automatic transmission gearbox has bands and clutches, which can get worn off prematurely due to excessive stress and pressure applied to them. When revving, the bands and clutches tend to slip when the car launches.

Do not Shift between Gears While the Car is Moving:

Always make sure that you come to a complete stop when shifting gears in an automatic transmission. Bands and clutches are responsible for gear changes in an automatic transmission. These bands and clutches have friction material linings in them, which last a life time. When the car is in motion and gears are shifted, a lot of load is applied to the bands and clutches, which damage the frictional material, ultimately damaging the transmission.

The above mentioned are just a few important things a driver should keep in mind when driving a vehicle with automatic transmission. It is recommended to get the transmission oil checked every 5000Km-7000Km. Always use the transmission oil recommended in the car’s owner manual.

    Proof reading is required

  • Ahmad

    unfortunately we have pseudo intellectuals copying stuff from Engineering Explained YouTube channel and quoting it here.
    Also boss when you copy and paste, please proof read it first, your mixing two articles.

    It would have been if it was a genuine article.
    Stop copying

  • Hassan Dar

    i know right..!! its been going on a lot on pakwheels lately..!!

  • Ather Rehan

    Guys, above all information regarding AT Transmission becomes irrelavent now as we have Cvt transmissions in the race for all latest car manufacturers world over.

  • Ahmed Hembel

    Please don’t do this. I don’t know who proof reads these before publishing them but it seems like there’s no one to moderate. At least get a permission from the guy before copying his stuff, or just give him a mention. And if you care about informing people so much, just share the original video on Facebook. I can’t believe that a platform like Pakwheels is letting this happen.

  • Zulfiqar Ali Soomro

    Well EE also has a video on what stuff not to do with a CVT. So im expecting an article over here soon with copied content from there :p

  • Mohammad Saad

    All the comments you guys are making here.. I really don’t know what you guys expect from pakwheels. @ahmedhembel:disqus I want you to google this title.. im 100% sure u will find 20 different websites with the same stuff the guy at engineering explain said. @Ahmad.. what do you expect? you want the guy here that wrote this article to come up with some research or new thesis? common man seriously? @aflatoon92:disqus Ok fine the guy that wrote this article got the idea from engineering explained. well atleast among all the sites you find on google I must say pakwheels is one website thats representing pakistan.. i always compare the comments i see on other australian and british car magazines, people there have civilized comments, they don’t remove pointless errors. I am a regular pakwheels blog follower and i must say pakwheels and their content team is doing a great job. They are the only pakistani website out there with content that is international in standards.. You guys need to appreciate this.

  • Mohammad Saad

    What happens if he copies it? This is what content writing is all about isnt it? Im sure you will find 100 other blog sites that have copied their idea. Do you what pakwheels to start researching on new automotive technologies? common.. they are doing a great job..

    “Do not Shift between Gears While the Car is Moving” I often change gear while driving hilly areas. I don’t think it is damaging transmission, If this has any problem when they made it easy to change between gears while driving. I often change 2 to L or L to 2.

  • Zulfiqar Ali Soomro

    NO YOU WONT. Not like this. With the same title and flow of the content. He wants to do it, fine, but at least give credit to someone who has actually RESEARCHED on this stuff and brought in light the information regarding this matter (and this has not happened just once). Thanks
