How bad is the Auto Trans on tC?

Ok, I'm just wondering how bad the auto transmission is treating all of you tC owners out there that picked it over the 5 speed. I live in central new york, and I have to deal with bumper to bumper traffic all of the time. And wether it's to and from work or school, there are too many annoying hills. Oh, and I live on a damn hill! I'm just wondering if i forego getting the stick if i'll regret it with choosing the automatic. Does the auto require a good shove to get it to downshift? Is there overdrive? If driving it normally, does it quickly shift through the gears, or does it take its time? I think I'll just deal with the side effects and get the stick, but I'm just wondering how life would be if i chose the auto...:rolleyes:

I joined to let ya know.. figured i've had the auto tC for 7 months now.. and it's the best auto I've ever used. On hills, there isn't a problem with shifting, it is smart enough to know to hold gears when going up hills and when going down them. There is a lot of power in the tC's engine so a "good shove" on the gas will usually just accelerate the car quickly going further usually caused a nice downshift and the car just really takes off (you'll hit the car in front of you if you do this.. it's quick)..

I haven't noticed any lag with the transmission, it's always in the right gear all the time.. I have driven stick before and when I would drive stick i would want to hold the gear around a corner.. I've noticed this auto does that.. It's also quite smooth.. hardly can tell it's shifting which is pretty good for an auto.. I have never been able to notice it downshifting as I am stopping, but watching the tachometer I can see that it is.. only time the shift was something I could feel is when I hit the gas to downshift and it shot up to 5000 rpms.. This is when I had to make sure I steered around the person in front of me that I was going around, otherwise i would've smacked into them it was that quick!!.. I love the car and the auto doesn't detract from the car's sporty nature at all!

Have you been able to test drive an auto? I think you should.. you'll see what I am talking about. The stick is decent, but a little too notchy for me when I test drove a couple of them. Plus there have been people with problems with the manual in that the transmissions are getting replaced for problems. Not to persuade you against the manual, just letting you know. it's one reason I went with the auto.. I think it's the best auto i've ever had in any car. hope that helps.. oh and at highway the rpms at 70 are 2800rpms with the auto.. the manual at 70 is 3500 rpms.. since it's geared lower.. just to let ya know..

Wow, that's awesome. I'll definitely try to make it out to my scion dealer (it's not exactly next door which sucks) to test drive one. I don't think I'd mind getting the automatic seeing with how pleased you are with yours. I also have another friend who got the auto in his xA, but he doesn't know how to drive a stick, but he loves the tranny anyway.

Ty for the quick response :)

hey you're welcome for the response. I would imagine the tC's trans is a bit different than the xA.. because the torque in the tC's engine is so much more.. Yeah definitely get out to a dealer and try out the auto, let me know what ya think.. I'm curious to get your reaction to it. But yes I am definitely pleased with mine, I used to have a honda civic (1996) with a manual transmission. Now that manual was "smooth as butter", but in this auto, I don't even miss the manual.. I know it scared me i thought i'd miss it, but it's that good. People have said the manual is quicker, and yes it's geared lower for faster acceleration, but it's like 1/2 second quicker 0-60mph.. not much in my opinion to really notice.. so yeah let us know how it goes at the dealer :D

YAY!! I live in central new york, and the only dealership i WAS aware of, is out in yorkville, NY, where my buddy bought his xA. But as of yesterday, Romano Toyota of E.Syracuse on erie blvd now has them--it's about a 2minute drive from my house, woot. Anyway, I just stopped over there and they had two.... with sold stickers!!! But I finaly got to see one in real life, and all i can say is that it's everything I thought it was. I spoke to someone there and he gave me his card and we setup a time to meet next week for a test drive and possibly take this further (hopefully!). The downside is that he said he wont be getting any 5 speeds for a couple of weeks, but he'll have more auto's there in a couple of days. So i guess ill get what i wanted, which is to test drive an auto. I'll post how it goes later :)

it may be the same transmission but the gearing is different in the tC than the camry.. I've driven the camry with the tC's engine and an auto.. much more lag in the gearing.. the tC is more responsive.. might be the same transmission but the gearing is different.. much improved over the camry's implementation of it

I think 7.4 and 8.1 are two different times. I guess it all depends on how you plan to use the car. I thought about getting an automatic, but I really plan on modding my car over time so I figured it makes more sense to get a manual.

What do others think?

sciontc_mitch is correct in pretty much all that he said. the At is geared differently than the MT, probably to overcome what are usually shortcomings with ATs. at takeoff if you're not careful it'll whip your head back, and the accelleration at passing speeds is quite fun. I just recently went on a 5 hour drive on some very twisy, technical roads. there was a manual tC ahead of me for a good part of it and I was totally able to keep up, including coming out of corners. (I think I actually may have out accellerated him on the longer straightaways.) he was behind me for a while, too, and it seemed like he kept up just as well as I had. mind you, neither one of us is an expert driver, far from it, but I think that levelled the playing field.

in other words, I believe the AT tC to be at least the equal to the MT tC.

The gearing isn't any different you guys. It's the same U241E as the Camry, but the shift programming is definitely more aggressive. However, it's still not as efficient as a manual.

It's funny what the transmission control module can do: Comfort vs. performance.

Now if we can get Toyota to give us the 5-spd auto ... it'd be much fairer.

U241E for both Camry and tC:
1st 3.943
2nd 2.197
3rd 1.413
4th 1.020
Diff.: 2.740

get the manual transmission, you will be glad you did, traffic asside... im on long island in traffic everyday... theres traffic upstate? ha. anyway yeah it will be annoying at times, but then theres the times on the open road or in the twisties where you will praise the day you went with the manual. plus you dont want people to be checking out you car in the parking lot and look in the window and say, "its an automatic.. lame"

if you want better gas mileage get a prius. thats no excuse

You wouldn't want it after a week if you value performance at all. The gears would be much too tall for the engine to lug through. You would definately need some form of FI to pull through them.

Toyota has never been known to change their gear ratio's around so it's fairly doubtful the i4's will see a 5 speed A/T in any part of their line. Especially considering the mileage most get with the 4 speed.




The number of gears is a moot point to begin with. It's all about what you do with the power you have. The more acceleration gears you put in a transmission, the more time you spend shifting instead of accelerating. ;)

well I have a couple of points here..

- what does other's opinions matter? if the person wants an auto and likes it, then that makes him happy, who cares about a manual..
- before people begin to say the automatic is so bad, have they even driven it? not right making a blanket statement like that..

- yes i have an auto and i am not defending it.. what I don't care for is people saying someone should buy a car based on what OTHERS think of it! Thats crazy seeking others approval for what a person drives.. I could care less what others think of what I drive.. I like it.. that's good enough.. :D

- and the auto vs manual.. if someone tells me it's more "manly" or "cool" to drive a manual i'm going to laugh so hard i'll cry! what does masculinity or coolness have to do with a transmission? It was a piece of machinery last time i checked.. and to be fair.. the manual is quicker, since it has more aggressive gearing, but.. It's too much for me at highway speeds to be turning nearly 4000 rpms at 75 mph.. It needs a 6th gear ..Yes I have driven a manual and it was too much at highway speed, sure it was fun around town but with all the highway driving i do.. I took the auto instead. It's not a slushbox by any means.. I think toyota did a great job on this auto, no lag, smooth shifting, i'm impressed.. :clap: and it has lower rpm's on the highway.. As far as acceleration 0.5 of a second difference between the auto and the manual in 0-60mph times.. isn't much of a difference on the street anyway..

bottom line? i think if the person likes the auto.. get one, be happy.. it's still a great car

who said an auto wasnt cool/manly? in my humble opinion a manual transmission gives you a litlle more control over your vehicle, you control the shift points you control the clutch slippage, and so on. im not saying it makes you less of a man. i feel its just a shame to have the option and not take it. hell i even own an automatic... strictly for drag racing though ;)

:eek:: Yeah all the transmission should be made 1 speed since you will spend more time accelerating and less time shifting right??? Wrong. Learn about gear ratios and short vs tall gearing and how having close ratio compares to lesser gears that are spaced apart since you don't have clue what the hell you are talking about.

To be fair, the act of shifting does take some time and slow you down a little bit, but that's usually offset by the efficiency of the gearing. For example, the Subaru STi is usually rated about 0.1 seconds slower than the Mitsubishi Evo8 in a 0-60 because it has to shift to third while the Evo can pull it off in second. However, the STi makes up for it in the quarter mile where it typically beats the Evo by 0.1.

As an extreme example, take a transmission with like 50 gears. You'd make a lot of power, but you'd spend so little time in the power band compared to shifting that you'd be a hell of a lot slower than someone with just a few gears to row through. Sixth gear in a sex-speed is also often just an extreme overdrive, with plenty of close-ratio five-speeds out there (SI Civic).

Without going into too much details, it all depends on how a car has been geared. There could be good manual transmissions and there could be potentially bad manual transmissions with the same number of gears due to the gearing being too short i.e the 6 speed transmission on the Sentra SE-R Spec V. It is downright awful and the car would do far better with a 5 speed manual. That has nothing to do with the number of gears. The faster car with the proper gearing will be the one that pulls the strongest for a longer period of time per gear. If the gearing is made too tall and spaced far apart with less number of gears, it will spend a lot of it's time on the powerband where it makes little or no power since the revs climb so slowly. Good and bad gearing can happen with any number of gearings due to the fact that transmission is responsible for putting out all the power to the wheels that is being generated at the crank. It completely defeats the purpose of putting an extra gear if it could not be faster than a 5 speed manual with the same engine since there is absolutely no other reason to put another gear except for increased performance. Generally with a skilled driver who knows how to drive a stick well, a car with a 5 speed manual (i.e 2001 BMW 330i) will substantially be slower than a car with the same engine if and only if a properly geared 6 speed manual (i.e 2004 BMW 330i) is used.

Hmm, the more gears the less gap between revs. The less gap, the more you're able to stay within the peak torque range. Being in the peak torque range on upshifts = better acceleration. So why would a 5-spd auto with it's millisecond upshifts be slower than a 4-spd auto? Also, why wouldn't its performance be improved?

Look at the gearing between the U250E (2005 Camry I4), E351 (manual), and U241E. Tell me how the 4-spd would be better than either of the 5-spds.
