ok so i dont really no much about gearboxs and stuff but is it bad to rev up in nuetral with an auto then drop it into drive. I figure it cant be too bad since u dont have to step on the brake ,it slids right to drive. also since the car doesnt have tiptronic ( Which scion should deff. add) is it bad to like be in drive then drop it into 3rd. or its not recomended. I dont wanna try it and end out with something broken. Not that im trying to race with an auto cause that would be useless but ive alwasy wondered if it is possible.

 

no, you are driving an automatic, therefore, you are really only supposed to use P, R, and D. let the car do the rest.

what you are describing is called a "neutral drop" which is a terrific way to drop your transmission out of the car.

dropping it from d to d3 is also bad. the car isn't designed to be shifted like that. there is a difference between automatics and manumatic. an automatic is not designed for this kind of use.

manually shifting an automatic is pointless, automatics aren't slower because they don't shift properly, they are slower because they lose more power, and because they usually have fewer gear doesn't use the powerband as well.

if you want the car to downshift, do this: take your foot completely off the gas for a split second, and then punch it to the floor. the car will reconize that you want maximum acceleration and will downshift as much as possible to get you the most power it can offer.

so yes, don't do anything that you have asked about with your auto, you will hurt your tranny alot!

 

haha thanks. its always pondered me. i was thinking after i asked this question that an auto doesnt have a manual clutch for the driver to relieve any of the power either. so i figured it would be bad but thanks for the clarification. But howcome the scion tc doesnt come with tiptronic? that was almost y i didnt by that car. i almost bought a rabbit instead but im happy with my tC

 

Yeah, DON'T do neutral drops, my buddy destroyed a Pont. G6 Rental doing that...thank goodness for the insurance coverage on it, but they screwed him over so he had fun beating the hell out of it. But yeah, what you are doing is spinning up the motor in neutral and then engaging the rest of the components of the tranny. That includes the torque converter overworking, and the synchros screwing themselves up as they are forced to go from 0 rpms, since the car isn't moving, to taking the brute force of what RPMs you take the engine up to. I'm no professional but making something thats 0rpm and forcing it to do 4000+rpms all at once is VERY bad :D The G6 I think limits at 3 or 3.5k, the tC doesn't limit itself so be EXTREMELY careful if you accidently put the car in neutral while its in "d" and moving. I have done that once by accident while I was playing with 2nd and 3rd gear on it. The safest thing to do then is try to rev match it, but the other option is just to give the car enough "gas" to stay above 1k depending on your speed so there isnt too much a rpm difference. Toyo's are strong, but they can only be so strong and then nature takes it's toll. Now, off that rant, I personally like being able to downshift it to whatever gear I want, I don't like the tiptronic limiting you as to how far down in the gear selection you can go...although it is a great safety feature for those that make mistakes

 

not sure, probably something to do with money, and not having a tiptronic tranny that would work with the engine available. i mean, how many tiptronic transmissions does toyota offer anyway?

if you want to shift gears, get a manual, if you don't, get an auto.

 

The 08xB has it so for price point that is freakin awesome...kinda surprise they didn't offer it on the 08 tC but since it is its last year I'm guessing thats why

 

yeah, i'm aware of that, but it didn't exist three years ago when they were building the first tc's did it?

 

Rev dropping an Auto is BAD.

If you've driven the automatic awhile, you can squeeze out a little bit more juice if you're familiar with its power curve and shift points.

 

Yeah, don't do this. When I was younger and naive I did this with my '89 Camry. Now RIP.

 

Well if you want to rev/launch from a dig, press your brake pedal hard and to the floor. Rev ur engine to about 4/5k rpm and let go of the break. YOu WILL launch, and it won't be as hard on ur tranny.

 

going from D to 3 isnt really that bad is it? I use it when going down steep hills. I figured it is like how lots of autos have overdrive and just D..

 

That is a complete myth. Going from D to 3 or 2 or whatever is perfectly fine and safe and won't hurt anything. That is why they are there. However the catch is that you MUST!!! be traveling at an appropriate speed for which gear you are shifting into. For instance... don't go 65 on the highway and try dropping it to 2nd gear for a little extra power

 

right, but if you are doing say 45 and you switch it over to 3, it simply goes up 1k rmps and you dont have to use the brake dwon the hill.
