Re: Gasoline Prices Below 99 Cents/Litre By Christmas

Actually the issue described is common with EVERY automatic. If the drivers holds the gas to the floor, the ECU and TCM will decide not to shift until red-line. You have to lift to make it shift sooner.

If you think I'm wrong take your vehicle out and keep the gas pinned to the floor from 0 to 120 km/h.

As for the "air of superiority" comment, you missed my point. The point being is that you actually need to focus on the task of driving, not your hair, your makeup, the email from the boss etc.. Whether a vehicle is a utilitarian piece of machinery or something that you truly enjoy driving, driving is what you are suppose to be doing behind the wheel. Unfortunately all the technology they put into vehicles these days makes it so that more and more people are becoming disengaged from the act of driving and focused on everything else around them.

Depends on if the ECU is tuned for fuel economy or performance. ECUs tuned for fuel economy will downshift as soon as possible, and my Elantra does this unless I throw the shifter into manual mode at which point it will redline and then force a downshift if I don't do it myself. The XG350 I had before loved to ref up before downshifting, and I actually would throw that car into manual mode for the opposite reason so that it didn't rev so high. Different cars, different shift characteristics.

To claim all automatics do this is a misnomer. Prior to 2008 they might have, but a *lot* has changed since then, just like I'm sure a lot has changed with standard transmission cars since my father's Firefly.

if you floor the pedal, yes an automatic will downshift to the lowest possible gear, or if accelerating, will likely hold the gear until close to red line...however, no one i know drives that way...when you are stopped, you give it about an inch of throttle (pedal) and the car gets up to speed in a normal relaxed way, similar to how it would if you were shifting the gears on your own...in a manual, you don't floor the gas and red line every gear when you take off from a stop (unless you are driving a 5+ year old Honda Civic, with stupid ground effects, a big wing spoiler, a fart pipe exhaust, and wheels 4 sizes too big with so much negative camber you are almost driving on the inner sidewalls ).

In my day the automatic downshifting from 3rd to 2nd gear on the highway by depressing the gas pedal was called "passing gear"

quote:
Passing gear

An automatic transmission gear that shifts a vehicle into a lower gear for a short burst of extra power to pass other cars on the highway. The gear is engaged by sharply depressing the gas pedal. When the pedal is released, the vehicle returns to normal to normal driving gear.

And back in the day prior to ECUs there was a mechanical rod from the throttle to the trans and then vacuum modulators came along.

i don't really like the term "passing" gear...it isn't a gear that was made for passing...the term i was familiar with was "kickdown"...you simply went down a gear, the same gear you would have used when you were getting to that speed in the first place.

Please stop saying downshift when you mean upshift. Transmissions go up a gear to lower RPM on the engine.

I know. I just didn't want people to view your arguments in a bad light because you were using the wrong term by accident. lol

I meant to hop on the QEW and floor the Elantra on my way back from the store about an hour ago but with the fog rolling in this evening and the need to correct some issues with my Christmas light display (yes, my wife calls me Clark Griswold, haha) I decided to just head straight home instead. The Elantra has a redline at 6750 RPM. I know it doesn't come close to that when flooring it before upshifting, I just can't say for certain what the exact shift points are. I keep Eco mode enabled, which I am sure plays a part in how and when it shifts.

I remember this!! As a younger person driving my parents 1992 Ford Tempo...I4....2.3L engine apparently with a WHOPPING 98hp!!! That would explain why when I pulled off this manuever on some road trips that the car didn't really speed up that much lol.

Anywho, that being said, nitz has jumped into the small car market with a 2008 VW City Jetta...I know I know, I have the MK4 with some hideous front end, but I like it...its spacious for a tall guy like me and gets way better gas mileage than my pig 2007 Ford Freestyle...and with some personal changes in my life I don't need the CUV type space anymore, as well I get to go back to $55-$60 fillups and get more distance out of that tank now than I did before filling up for $80+ and getting around 550-600km in the city.

Anywho, gas prices hover around 126.9 in these parts...

I had a 1992 Topaz with the 3L Vulcan V6. Being a light car to begin with, it went zoom a lot better when you floored it than the I4s did.
