yes it will damage your engine if you revv upwhen alot when its cold because the engine since still being cold; the metal has not expanded and heated up to its proper temperature. thats why its called operating temperature. by you revving the bananas out of it will produce too much pressure within the block possibly popping off a coolant hose or stretching the timing belt....

Revving your engine when you first start it up and it's not warm yet will cause premature wear on internal engine parts. This is because after the car has sat overnight, the oil has had time to drain out of the top of the engine and back down into the oil pan. It takes a minute or two of the engine running to get the oil pumped back up to the top of the engine to start lubricating the moving parts properly. Also the metal parts haven't had enough time to expand from temp. change to their operating tolerances. If you're sitting still and the Trans. is in Park or Neutral, revving the engine won't have any detrimental effect at all on your transmission.

If you are holding a steady high idle (1200-1600 RPM's) it wouldn't hurt your Engine or your Transmission. But if your RPM's are higher than this, or revving the hell out of it then you will start noticing a loss of performance due to premature wear in the long run. The best example that I have for you is this, in my 07 VW, when I start up when the engine is cold, the RPM's automatically goes to 1500 rpm with my foot off of the gas pedal. So think about it, if a car Manufacturer is programming the ECU to command the engine to rev up to a steady 1500 rpm's, how could this be a bad thing???? On another note, they do this too control emissions after a start up by letting the catalytic converter reach it's operating temperature faster.
I hope this was useful information.......

Yes, it will hurt it.
"1. Start It Up Properly
"Most of the wear on an engine happens when you start the car," says Edmunds.com's automotive expert Karl Brauer. "If you can get the starter stuff down, you'll find cars will wear much less over time." How do you do that? Make sure any extra accessories, such as headlights or climate control, aren't on when you turn the ignition. If you do, you're asking the engine to work harder than necessary right off the bat.
An even more destructive habit: revving the engine. Believe it or not, this won't help warm up the car. In fact, revving can do serious damage to the engine and significantly shorten its life. Engines need oil to run smoothly. But right after you turn over the ignition, the oil is still sitting in the pan. When you floor the gas pedal, you're asking the engine to work overtime without lubricant -- putting metal to metal. Wear out this most important drive train component and you can expect to pay $3,000 to $5,000 for a new one."

It does not hurt the car but you are defeating the purpose of warming it up. The same parts are moving except the wheels. The oil is still cool so it is not lubricating correctly. To those who say you do not have to warm it up I would reread your owners manual if I were you. The manual says to warm up a car even if it is warm outside. Rool of thumb is until the engine sounds normal. When you first start a cold car the rpms are higher and the engine sounds more ruff. Let it idle until the rpms drop to normal idling speed and the engine quiets down. If you constanty start your car and just drive it while still cold it will wear it out prematurely.

As long as you don't rev the engine too high, like keep it down to about 2500 rpm or less. as far as the trans it depends on the manufacturer. Chrysler built automatic trans does not fill the torque converter in park so it should be warmed up in neutral so the fluid circulates correctly and doesn't burn the front seal or converter bushing. Some foreign manufacturers may be the same way. So I would recommend warming anything in neutral just to play it safe.

It is OK to ref a code I don't engine for a short period of time like two minutes as long as you don't exceed no more than 1800 to 2000 RPM sent the oil in your engine while sitting overnight etc. will drop to the bottom of your oil pan therefore your engine components are not well lubricated so it is not wise to rev any higher than that

Its not good for your car, it's basically the same thing as getting into your car on a cold morning, starting the car, and driving it without letting the engine warm...except youre in park.
If you're trying to "put some heat in the engine" – Don't waste your time, heat comes from load and there is no load in neutral or park.

As long as it has oil pressure before you "REV" it up. And that doesn't mean "pedal to the metal". But to bring the idle up in order to warm a car is ok. Just keep it below 2000 RPM. Any more than that and your wasting fuel and just being annoying.

As long as the gear shift is in Park or Neutral, it will not affect the transmission.
It will harm the engine. Give the oil, coolant, engine block time to warm up slowly.
