How do you launch an automatic vehicle? How does torque multiplication work? How To Launch A Manual - https://youtu.be/54I5RU-RNhQ Subscribe for new videos every Wednesday! - https://goo.gl/VZstk7 How do I launch an automatic transmission? The process of launching a manual transmission is straight forward, but there are a few variables you need to adjust for optimizing your speed. 1. Press brake firmly with your left foot. 2. Apply throttle, holding the RPM at a desired speed. 3. Release the brake pedal. 4. Modulate the throttle as necessary to control wheel spin. One of the impressive facts about automatic transmissions is that they are able to multiply torque through the torque converter, meaning you can use a lower RPM than a manual transmission vehicle and achieve the same initial acceleration. This is a result of a torque converter's stator, which redirects the transmission fluid flow leaving the turbine and entering the impeller, which sacrifices efficiency and speed for greater torque.

This is true if your engine control module doesn't cut torque or timing when you raise the RPMs before you launch.. I know many cars nowadays including mine will hesitate more off the line by building up RPMs rather than just flooring it. However if you have a laggy turbo car that allows for this then yes building up RPMs is the only way to get a great launch.

we need how to launch a CVT transmition!!!
-
think u probably should have started with the last part first then explain the process and what we doing to the car after. The last part sealed the deal for me. I can live without launching my car, it has a pretty good kick at stop and go. Pretty much so if im not careful ill be burning my tires too fast. Excellent work tho on all your videos.
Oh here is a question. Is it bad if im at a stop light and i suddenly floor the engine at green? -
what is it called when you put the car in neutral and rev it a little, then shift right into drive? will that harm the engine and transmission?
-
So what happens to the car when you press on he had peddle when in park? does it damage any parts of the car?

I have a honda CRV 2014 ... I know its not the CVT version... since it said 5 speeds when I bought it.... now of all the cars I have driven it feels a bit different. Not bad different - just different. Does it by any chance have a Hondamatic??? And how is a Hondamatic different from a regular Automatic?
-
my car dont have rev meter tf???!
-
thanks! it is good to know
-
Slamming it into reverse cancels out any damage you caused by launching forward.
-
can a front wheel drive be converted into back wheel drive
-
What a clickbait! How about launching your car with minimum wear to the power-train?

this is really just a stall test. what youre really doing is testing the stator in your torque converter. you hold the breaks as firmly as possible and try to bring the rpms up as high as it can reach most production cars are right around but usually below 2k rmp. this shouldnt be done for more than 5 seconds though or you will damage your transmisson due to heat. after each stall test or "launch" as youre saying you really should allow your torque converter to cool down before putting a real load on it. But you never mentioned a high torque torque converter where you can launch safely without making as much heat withen your trans. And EVERY car that has a stock transmission that is a production car newer than about 1990s has had a torque converter lock up clutch to reduce emission because a toruqe converter on its own is just a viscous coupling. its a torque converter because it has a lock up clutch. if it doesnt have it, its a viscous coupling at its most efficient sending 90% of engine power and torque through the trans

Can you do a video on neutral drops and why they are bad for an automatic transmission?
-
Best explanation of the topic ever, thankyou Gingerbeer Man.
-
love your channel bro
-
I thought he said "o man my balls" at first
-
Just want to say that launching an automatic is deadly for the torque converter. The reason the revs limit is because of resistance, not electronic limited. A blue TC is a dead TC.

wow xjawz really turned his life around

I got a Tucson 2016 limited and I got a heated transmission as I got stuck I. Traffic and I had to creep no other way of driving basically it was a stop and go situation I just bought it two weeks ago please help

is it safe to launch and auto with fwd . will it harm the car and if so what dose it do to it
