I was wondering if the aveo is a 4 or 5 speed automatic as the website lists 4 gears but when I drive I count 5 different gears.
i have a 2004 it's a 3 speed with overdrive.
four speed with o/d i think
4th speed is an overdrive. The "5th speed" you feel is the torque converter locking up.
reverse is a gear...
so the converter only locks up in 4th? im glad i got a manualQuote:

stick accelerates faster, but they both have about the same top speed
of course the manual is going to accelerate faster (most of the time), the extra forward gear allows the transmission to be geared tighter.
However; When in a slalom type situation where you're coming on and off the throttle constantly, often an automatic will be faster (if you can lock the gear). For some reason or another (maybe has something to do with the torque converter?), they kick harder in these situations (again, as long as you lock the gear).
i was counting the gears once too and it felt like five shifts...what your saying is the last one is the converter locking up?
Yes, last subtle "shift" is the torque converter lockup. Don't you have a tach even with the auto? rpms should drop ~200 rpm when the converter locks up vs the 1000-1500 rpm drop in between real gears. If you can't do it by feel, you can always look at the tach and counts how many times it shifts there, or do it manually with the lock feature. You just have no real control over the lockup cuz it's ECU controlled. It basically checks if you're more or less cruising at constant speed and if so, it'll lock it.
Some 4-speed autos with a hold at 3rd can lock the converter in 3rd. Since I don't know the Aisin tranny for the aveo, I don't know if it can...
On my old 89 Civic, I was able to de-lock the converter by pulling back on the shifter very slightly. If I didn't accelerate, it would lock back up after a few seconds... but it saved a few seconds when you had to accelerate a bit to pass by pre-unlocking instead of just pressing down more on the accel to have the ECU take a while to decide "oh, he wants to speed up, I guess I'll unlock the converter..."
i just hit the HOLD button and hit the gas and i'm cool i know that they say i have a 4 speed but it's a 3 speed with overdrive and the hold button works fine to pass cars on the freeway.
On my car though the "5th" gear drops about 800-1000 RPM's.Quote:

Doesn't matter what gear you are in, at a certain speed the converter locks up, at around 50-60kph IIRC Unless you have your foot down to the floor that is.

2000rpm=60km/hr on the "4th drop"
2000rpm=80km/hr on the "5th drop"
so this would mean that the last two "drops" are real gear shifts, so the "torque lock" happens anytime before 60km/hr. All the while i thought it was really 5 speed.
I refer you to this post: http://www.aveoforum.com/phpBB3/view...p?f=49&t=27350Quote:

But it ain't. It's a four-speed with a TCM program that can't be changed. GM put one over on us urban dwellers. If your driving is exclusively in city/local traffic, the FE sucks and you can't change it, no matter how you drive it. This car was designed to be pitched to and sold in rural America (or Canada, or worldwide). If you never do any city driving (under 45 MPH) it will be a wonderful car for you. If not, you're screwed, because it's a gas hog in the lower gears.
I wouldn't call it a gas hog... 20 MPG in city is still not that bad... Some cars I've driven had around 12 MPG in city and 22 MPG on highway on a very good day with only me in the car... 8)
"Not that bad" :?: Compared to what?Quote:

has you accelerator pedal stuck yet?Quote:

Compared to the CX-7 I described in the last post. It was a crossover SUV with a 2.3L turbo engine though.Quote:

I only fill the aveo once a week..
still comes from Japan though, this is a sorry transmission no matter what lolQuote:

dont like your aveo? I dont think you ever typed on here why you are selling or were going to sell your aveo?
It's a less sophisticated but very reliable transmission, also used on lower-end Toyota products. But Toyotas get better FE because they used the transmission manufacturer's specs for programming it, unlike the GM Aveo version.Quote:

Sooner up-shifts = slower performance, but better FE.
Apparently Chevy programs all their slushbox automatics the same way. "One size fits all."
I did. It's in my for sale thread. I like my Aveo, just at the moment I'm between jobs after I got out of military and paid off credit card sounds better than a custom ride. If everything goes well at the interview in middle August to get into welding training program for veterans, I'll be keeping it for the 75 mile commute to the training facility. 18 weeks of training, 75 miles one way, equals about 13.5K miles commute ... so if the training will be a go I'll be keeping it. And I'd get the Mazda just cause I thought it was a great quick crossover suv that's fun to drive.Quote:
