This thread is awesome.

 

[Capt Caveman]

I called it. Fleabag2, CONFIRMED.

Yeah, he's been like this for a while, I just didn't want to call it. Car expert who buys a Corolla and disses the whole time. Makes sense.

Then he tows with it. /facepalm His knowledge/experience comments on automatics is so Fleabag.

edit - I've owned numerous vehicles with automatics and done quite a bit of towing, I've yet to have a transmission problem with any of those vehicles. Heck, I've never had a transmission problem. All sorts of other problems but not transmission. Knock on wood.

You're not doing it right. Maybe OP can give you some pointers.

For starters, you sell that piece of shit and buy a real car with a manual.

There's a reason big rigs always have manual transmissions. Jesus would drive a manual (if he were real).

 

[Malak]

I'm surprised the engine has lasted this long since the transmission is all too eager to redline the engine every single day. That manual Civic I had before this never once hit redline.

Funny since everyone else's auto doesn't have any trouble, just yours.

All of the vehicles I'm looking at only offer automatics. Oh noes!!!

Oh noes x2!!! New BMW M5 is now available only with auto (no DCT, auto-auto) as well!! Oh nooooo~

Ok, how about this. For starters, you trash that piece of shit driving habit and learn how to drive properly.

 

[ShawnD1]

But captain, surely you cannot expect the transmission fluid to shear more. She's shearing as hard as she can!

Ok, how about this. For starters, you trash that piece of shit driving habit and learn how to drive properly.

Please explain. In a past thread I said I accelerate at such a rate that the car reaches the 40mph speed limit in second gear then it drops to fourth gear. You guys said that was too aggressive. Then I complained about the transmission constantly lurching back and forth between gears 2-3-4 when accelerating up to 40mph and you said that too was wrong. What is the true correct way to drive an automatic transmission?

Driving a manual was way simpler. Just put er in a high gear and floor it. If it chugs, the gear is too high. If it jerks, the gear is too low. Simple as pie. Automatics..... complicated as figuring out how not to melt the torque converter D:

 

[evident]

ok fine I'll stop trolling and trying to anger people.

I'll update this thread after I take the car in and get an assessment done. It's probably something simple like changing the ATF. What's weird is that I took the dipstick out yesterday and right on the handle of the dipstick it clearly says that the ATF should never need to be changed. That seems like a very strange thing for a company to say. Around the AT Garage it's assumed that people change the ATF every once in a while.

toyota uses atf rated for the life of the vehicle, i believe. i'd still change it ever 70k or so even then

Would you behavior change depending on whether or not you are still under warranty?

I ask because someone posted something about changing behavior after warranty ended. Under warranty, they took it to reputable mechanics to have the oil changed just so there was a record. After the warranty, they did it themselves.

 

[zoiks]

someone doesn't know how to drive

the corrolla is not a performance car
nor is it a tow truck

stop killing your car by trying to drive it like one.

just because you car died to due driver retardation doesn't mean the company/cars are trash.

From the other thread I do see where he says that he'll tow a Uhaul but did he actually do it?

 

[Capt Caveman]

I've had my atf changed once in the 11 years I've had my QX4. Never had an issue with the transmission. Even pulled a large uhaul trailer from SF to Seattle. But my vehicle also has a tow rating of 5k lbs.

 

[JCH13]

:hmm:


:awe:

You killed your car by driving like a dumb ass. I'm going to ignore everything else you've said in the thread that's so flame-ably wrong, your broken transmission speaks for itself.

 

[PlasmaBomb]

That's how most people drive an automatic. You put it in "drive" rather than L or 2.

In your other scenario you should really have stuck the transmission in 2 if it was bothering you...

It's also worth noting that the act of changing gears is what wears out the clutches and burns the oil.

If you are changing gears properly you shouldn't be killing the clutch.

If it were up to me, it would stay locked in top gear.

If you labour/lug the engine you aren't doing it any favours... That's one of the best ways to ruin a modern engine...

When left up to the automatic transmission, it shifts gears around 20 times per minute. Imagine yourself driving a standard and while driving you are constantly pushing and releasing the clutch. That is exactly what an automatic does, and that's why the transmission is broken. My Ford Tempo had the exact same problem and most of the old people around me thought it was perfectly normal for an automatic to not have a clue what gear it should be in.

Considering that the Corolla would have a slush box that is exactly what it doesn't do...

Also that's like one shift every three seconds...

Absolutely. Even the US government agrees that automatic transmissions generate fuckloads of heat and are going to burn the oil just by using the car as a daily driver. Forget my autotragic corolla and look at my old 1992 Ford Tempo:
http://www.fueleconomy.gov/feg/compx2008f.jsp?year=1992&make=Ford&model=Tempo&hiddenField=Findacar
18mpg automatic vs 21mpg manual. Where do you think that extra fuel goes? It's heat in the transmission. Forget about how hot your exhaust system is, consider how hot the transmission is when 14% of the energy (3mpg out of 21) heats the transmission. That is why the ATF turns into black tar and that's why I had to sell my Tempo after 1 year of owning it.

Well done... assume the whole difference in fuel economy ends up in the transmission.

/facepalm

The Crayola is the same story. Right in the first post of this thread I said it was burning 9.6L/100km in combination city/highway driving. When I first got it, it would burn about 7.6L/100km. Where is that extra 26% fuel consumption going? Heat into the transmission. It's a million degree blast furnace inside that transmission. No wonder the thing is fucking up. That's the energy equivalent of holding a blow torch to the transmission.

The difference is 2 L of gasoline per Hundred kilometres...
So that is 0.02L per km.

Wiki puts gasoline at 114,100 BTU per US gallon, so that is
(114100/3.7854)= ~30142 BTU/l

Since we used 0.02 litres that would be -
30142 x 0.02 = 602.84 BTU

My propane blowtorch is rated at 7.7 kW, so convert BTU to kW -

(602.84/~3414) = ~0.176 kW or 2.3% of the energy in a burner, under the worst possible situation (that all extra energy ends up in the transmission).

In reality the inefficiencies of the ICE mean that 66% of the extra energy will likely go out the exhaust...

Which reduces the extra to ~0.05 kW/km or 0.76% of the power of the blowtorch.

For comparison sake, my manual transmission Honda Civic had the same 7.6L/100km city gas mileage for the entire time I drove it, which was 3 years. The only reason I no longer have that car is because some kid t-boned it. After 50,000 miles (80,000km) it still had the original brake pads too. Honda = good. Toyota = proof that 2 atomic bombs was not enough.

Shawn... Honda and Toyota are both Japanese...

Fuel economy doesn't tell you the whole story. Manuals for most people get fairly good gas mileage but not great because people (the AT garage) love to run the engine at super high rpm all the time and refuse to upshift.

The only person in ATG that I have seen recently taking about "super high rpm" was you, when you were comparing a gas engine at 5700 rpm to a diesel at 2000 rpm...

Surprisingly that weight in the trunk has almost no effect on gas mileage. The Civic didn't take a hit either. Of course that should be expected since a Corolla and a Camry get almost the same highway mileage despite one weighing 500 pounds more than the other in addition to having ~40% more horsepower.

Toyota: making it stop because the piece of shit automatic transmission doesn't work
about the weight thing:
Toyota Camry - 33mpg highway - 3263 pound car
Toyota Corolla - 35mpg highway - 2734 pound car

Oh noes!!! Adding 500 pounds of weight to the car drops the gas mileage by almost 6%!!! Shit! (35-33)/35 * 100 = 5.7%

You do realise why DBZ was laughing don't you?

By the way thanks for disproving your own point (bold).

Lol, no. I sure as hell don't drive around in 5th gear flooring it. I actually rarely floor it, half-a bit more throttle is usually all I need to get up to speed nicely. Only time I floor any car is if I want max acceleration, auto or manual.

 

[PlasmaBomb]

Lets call in some korean engineers to fix this.


Also, have you inflated to max sidewall yet?

Korean engineers know nothing! We must go and find Fleabag!!

 

[exdeath]

A properly working auto doesn't slip all the time, it only slips for a split second when making a shift. Under normal operation the clutches and brake bands don't slip any more than a clutch on a manual does when you aren't shifting. Most of the heat is caused by the operation of the pump and torque converter, especially when it's not 1:1, as in engine revving but vehicle barely moving due to load. Under this condition the fluid heats up and the other parts including friction material expand and break down prematurely as a result of inadequate cooling or wrong vehicle application.

 

[ShawnD1]

That's the main complaint. Constant shifting between 3-4 even on flat ground with the cruise control on. The car has a very strong bias toward changing gears rather than giving it more gas in the current gear.

You do realise why DBZ was laughing don't you?

By the way thanks for disproving your own point (bold).

This thread is awesome :thumbsup:

The 500 pound difference from a corolla to a camry is a weight increase of 18.5%. On top of that, the camry has a 2.4L engine instead of a 1.8L engine which would be a displacement increase of 33%. So after adding 18.5% more weight and increasing the engine size by 33%, it only drops the gas mileage by less than 6%. In the OP, the car is burning 25% more gas, and you're trying to tell me it's caused by added weight? How many tons of weight do you think is in the trunk?

Well done... assume the whole difference in fuel economy ends up in the transmission.

/facepalm

So the reason automatic transmissions require a special after market cooler to prevent them from melting is because the tranny is being attacked by radical islamic anti-transmission terrorists. Got it. There's no way the simplest explanation (excessive heat) is the correct one.

Nope. I said I drive around in top gear and ATG said that was wrong. If you're not in top gear, which gear do you think the car is in? The gears in a corolla are listed here. Gear 4 is 0.892 while gear 3 is 1.296. If the car is gently cruising at 1800rpm, dropping out of the top gear would change it to 1800 * 1.296 / 0.892 = 2615rpm. Understandably, doing that drops gas mileage by a lot, and this is what ATG is saying should be done. Do you guys always drive around at 2600rpm? My car would drink more gas than an M1 tank if I drove around like that all the time.

Big rigs have been available with automatics for a long time. We had them in the military in the early 1990's. 5 speed automatics, actually ten speeds.

Yes, I rarely drive below 2k rpm in anything other than 1st or 2nd gears. Not much torque down there and it lugs the engine. 5th on the highway = ~3k at 70mph. Most 4cyl cars will turn that speed at that rate.


edit: and you are forgetting manual transmissions can need oil coolers as well, especially if you track it. Anytime you've got oil moving around in some fashion like that it will need some sort of cooling, but generally the surface area of the transmission is enough.
