What is more hard on your engine and transmission? (for autos)
What harms your engine and trasmission more and is more likely to lead to a blown engine?
1. Revving your engine to high RPMs in park or neutral.
or
2. When youre cruising at like 20/30/40 mph and you slam on the gas and it downshifts to like 6000rpm.

You'll be fine either way. Neither of those are all that harmful.
However, if you're looking for which will cause more damage over time, I'd say revving to redline in neutral.
Why are you revving to redline when not under load, though? To 'show off'?

Pretty much, i love that injen intake. And i love revvin it under a tunnel, 1 time an old lady infront of me in an old Geo had her window open and spilled her coffee everywhere.

Anyway, as long as your engine is maintained well neither should harm it. Eventually things will wear out more quickly, so it isn't like it 100% will explode if you do it.
But, I don't think the engine was designed to be spooled up to redline so quickly under no load.

I was basically asking for a ticket by backing up for that long on the highway

Stupid and useless thing to do. Why is this even a question? 
Definately puts a strain on the engine and tranny.
It's your car, drive it how you like.

Haha, Oh God your story reminds me of a story too. One day I was following my brother-in-law following him since he just bought a car and needed someone to drive one of the cars home, and he in his new car, drove past 5 lanes on the high way, and I was forced to follow him, I got past three before a truck wouldn't let me pass, so I ended up getting pulling into a emergency lane a couple feet away and slowly went reverse on the freeway until I got into the exit!

I think everyone Is forgeting the most important one here, that is if you are reving your car in N and slamming the car into D than you might have just killed the tranny and that might be the last of It. If you are shifting your car in to 2nd and 3rd and than into D that will toast the tranny also.

However, manually upshifting will do no such thing.

When im in stop and go traffic, under 35 MPH i keep her in 2nd so she doesnt have to shift, and when the time is right i move her into D and thank god for a lil thing called the Drop Resistor, which than decides when it is a same time to actually shift into 3rd.

This also can cause some damage to the tranny and engine when It's very cold outside and the car was not warmed up and you just take off and you will redline it the car will take off but when your coming to a stop the car will studder bad and misfire.
Whoops, I ment 1,2,D I guess It's one of those days.

Hey I am not sure if this is true or not but I read something a long time ago called like "proper transmission etiquette" for a automatic transmission and I remembered little rules that I still follow to this day and they are:
1. Always move the gear selector from P to D or whatever slowly, stopping at each one in between for a few seconds to allow the car to properly shift.
2. When moving from D to R or vice versa, always come to a complete stop then change the gear to R or D and wait for the car to shift for a second or two then begin moving again.
3. When going up a steep grade or before beginning to go up a steep slow put the car in gear 1 or gear 2 and keep it there until you reach flat ground and then shift to D. (I personally think this is a little ridiculous as going constantly in one gear can't be good for the car and with the amount of slopes in the area where I live I think it would do more harm than good)
4. When going down a steep grade shift to 1 to allow the engine to brake for you. (Something I also don't do)
There are many more, like when you first start your car go through all the gears and allow each one to shift fully before beginning to move your car. And also something like, you apply the parking brake first and then move the gear to P and park.
Not sure if these are true or not. But I follow the ones I see are reasonable haha

honestly Leo. Just stop the Car before ya shift from Reverse to Drive and vice versa. thats about all ya gotta worry about.
i know that, did i type something incorrectly? if so i appologize.

Hahah thankyou! I really didn't think about it until I saw this thread. I've always read that automatic transmissions always need fixing sooner than a properly used manual, so I was worried
