After 2 years with my Yaris I have one complaint

[regal]

It needs a six speed manual transmission, it just pises me off reving too high at 65mph wasting gas. I plan on keeping this thing 20 years as I am just don't like hybrids (due to long term maintenance issues.)

As anyone found a bolt in 6 speed? Will the new Yari's have a 6 speed?

[marcus]

someone did a swap on his tranny..try to look it up..

[brg88tx]

i can't complain, i still get 38 mpg with the cruise set on 78 with my automatic sedan.

[Bredayaris]

Here in Europe you only get the 1.0 vvti with a 5 speed transmission.
The 1.3 and 1.8 petrol and 1.4 diesel have a 6 speed transmission.

[Hershey]

Go in between with a 5 speed automatic or a C.V.T.. Could bump up the mileage . Better coasting . Notice this with the 2011 FIT with the 5 speed auto . We test drove a SX-4 wagon all-wheel drive with a 6 speed manual and another with the C.V.T. on the same roads / streets . The C.V.T. would coast better .

how high does your revs get in 5th @ 65mph? :iono:
you sure your in 5th gear not 3rd? :iono:
maybe time for you to replace the clutch :iono:

In 5th at almost 70, I'm floating 3k rpm, 65 is about 2800rpm. Which is incredibly too high. I don't understand why Modern MTs don't always have a 6th, especially if one is already in production.

As previously eluded to is that our American engine (nzfe) is the top of the line n/a in Europe, they also have the sales and consumer base to have complaints refine the manufacturing. I believe it is the top selling car in its range in G.B. since 1999. Also Europeans sell so many more MTs and would hurt sales if it was only a 5spd. Why would Toyota have cared here in the states with a hugely disproportionate AT to MT sales, when the 5 to 6speed saves them in the long run. (the echo was great but didn't sell well in the states unfortunately)


I would be leery of a CVT they can shift faster than a human but have enumberable moving parts in compared to a MT. Toyotas CVT may be nicer but I prefer a standard.

The clutch really should not have anything to do with RPMs at speed.

[Flipper_1938]

My 01 Echo had a lot taller final drive ratio. I hated the Yaris transmission almost immediately.

[NZ-FE Vios]

I haven't done any research but has anyone changed the final gear in the Yaris at the same time as clutch? Is there a different 5th gear that can be swapped in? I would think it would be cheaper than doing whole trans and have a similar affect as 4th and 5th gear are close in ratio

[enviri]

3k rpm @ 70 is too high? I've owned a good amount of japanese cars and i just find it being normal?

[regal]

Roughly guessing there is at least a 5gp boost if a 6th speed dropped the rev's to 2000ish. My guess is the engine doesn't have enough torque to be "safe" on the highway, probably some stupid safety regulation put in place to keep the mid east oil rigs pumping.

[NZ-FE Vios]

A friend had mentioned something along those saftey lines in re to civic and that's a 1.8 with a bit more power and torque. The gov also most likely doesn't want us to be able to cruise near 90mpg at 3krpm

[Brianr4]

When I installed my tach my first thought was wishing I had a 6 speed to drop the rpm's down.
We would be looking at close to 50 mpg!

[DMZ]

3k rpm @ 70 is too high? I've owned a good amount of japanese cars and i just find it being normal?

Yep.

I recall my 72 Subaru GL would show 3,460 RPM's @ 70 MPH. It had a 1.267L EA - 62 engine. Albeit, with a 4 Spd manual.

[bronsin]

A 6 speed transmission is NOT necessarily better for mileage. It all depends on the ratios. If 5th and 6th are numerically the same a six speed will use MORE gas! You have one more gear to accelerate in. The ideal would be a three speed with numerically identical 3rd gear to a five speed 5th. It would work here in flat NJ but probably not in hilly country.
SIx speeds and even five speeds are stupid consumer driven idiot inspired devices. Auto trans are similiarly going through the idiot process of more and more speeds.

I disagree. In some cases it is not necessary, but in these times when you want to eek out as much gas mileage as you can, the right gearing on a 6 speed will help tremendously.

To the Op, there is a 6 speed that fits, but If I remember the final drive might have been numerically lower, meaning it would get worse gas mileage. If you could swap the Echo's final drive in that woud be much better for gas mileage. Not sure how much that would cost though.

When the Yaris came out I noticed that the rated mpg was less than the Echo's. I think the last year Echo was 43 and the Yaris was 40 highway. These are before EPA changed their rating system. This explains a lot.

[Yaristeve]

3k rpm @ 70 is too high? I've owned a good amount of japanese cars and i just find it being normal?

I agree. These cars only have a 1.5l engine. If you think the Yaris is bad, my IS300 5-speed, with the 3l, 2JZGE inline 6, unbelievably revs even higher (about 3300rpm @ 70 in 5th gear) than my Yaris 5-speed. But that low (numerically higher) rear end gives it a lot more pep than 200hp really should. But mileage really takes a beating, the best I ever got out of it is 30MPG at a steady, cruise controlled, 70MPH...

[Idahotom]

Higher and higher gearing can be overdone. Just try driving the 5 speed in top gear at 35 mph and see how good of mileage you get. While the rpm's may be construed as "high" (relative to what....) the engine is not working hard/manifold pressure is low. Granted it is a balancing act, and in theory I'd like a 10 speed to play around with, but I don't sweat not having a higher gear in my Yaris as much as I do not being able to open my rear windows!

I've seen different airplane drivers fooling around with ground adjustable pitch props, going coarser and coarser (like higher and higher gearing) hoping and getting lower revs at a certain cruise speed, but you reach a point where the economy doesn't improve past a certain point. Let's face it the Yaris is a inexpensive car, so the engineers' split the difference, a 5 speed instead of a 6 is one of those compromises. If you are obsessed with lower revs at a certain speed, it would be more practical to get larger tires and wheels. Keep in mind they'd weigh more and raise the vehicle thus more drag, probably canceling out any gains in MPG.

Well stated. I know from operating both 2 and 4 stroke motorcycles most of my life that there are "sweet spots" in the power curve, where the engine is operating efficiently and with little effort, (it is usually on the front side of the torque and HP curves). This is where you want to be to maximize your mpg, but also to extend the life of the engine. For a Yaris 1.5L, that seems to be between 2,250 and 2,650 RPMs. That is where my engine is most :biggrin:.

[NZ-FE Vios]

I'm sorry but what yall are forgetting to take into account is that in Europe out 1.5 comes with a 6speed

Echo was 3.54 final ratio. Yaris appears to be 3.72

That is only 5% different...sure seems more.

The diesel in Eruope has a six speed with 3.55 final ratio and more overdrive on the higher gears. It would be nice to get ahold of one of those it it would bolt to a gas engine.

[why?]

obviously, and we don't have the right gearing with the stock transmission. You just get a wider spread of better with more gears.

[Brianr4]

Well you are correct if the last gear for a 5 speed was the same as a 6 speed. I was looking at the transmission in the car now, but wishing it was 6 gears instead of 5. Which would obviously make the 6th gear a different ratio than the 5th.

[Idahotom]

I had a Dodge Colt in the early 80's, made by Mitshibushi. It had a two speed transfer case, and a 4 sp. tranny. It was a ball to drive, having two speeds in reverse was fun also! The concept never seemed to catch on, they only did it for a couple years I think.

[Blue Y job]

It's always a compromise. More gears cost more. But more features attract more buyers, if the price is right. Price it too low, and Toyota wouldn't make enough $ per unit.
I think it's geared pretty good. A six or more speed would be nice, but my car was so affordable when I bought it, it was a selling point. And the way the engine was designed and with the small displacement, it would be a complete dog at 2000 rpm at cruise speed. To change your speed or to go up even a slight hill, you would have to downshift.
In the Mustang world, it's the opposite situation, most everyone wants to make the engine spin more for more acceleration!:burnrubber:

this car is so light you almost need no torque to get the thing moving. Cruising at 2000 rpm is fine, and a stab of the throttle is all you need in most passing situations.

The problem is 1st gear and fifth gear are terrible. 1st is too short, even stock cars can spin the front tires too easily, and 5th gear is basically worthless, the difference between 4th and 5th is barely noticeable.

They should have stayed with the gearbox from the echo. Or at least 5th should be a proper overdrive gear.

[Bluevitz-rs]

That would be me... :cool:

The thing is, I'm getting better millage now with the 6 speed even though it revs HIGHER than the stock transmission. @100km/h it's now turning 2950rpm instead of 2600.

Process that one :biggrin:

It's not about revving lower, it's about running the engine more efficiently. And for the most part in the city I don't need any more than 2000-2500 in any situation because the gears are SO close together.

But if you're inclined to swap out an echo 3.5 F/D into the yaris, I have my old tranny guts for sale.

[N464AT]

Anybody figure out to drop a Camry V-6 in a yaris hatch yet?

[Bluevitz-rs]

Yes. But you'll need one of these.

It wouldn't bolt on.. the D4D engine is far different in shape than the 1Nz.

I can't possibly think it would be worth it, unless you had a spare camry engine and can do all the work yourself.

The revs for your car are normal and 3000rpm at 70mph the car is not working hard,it was designed to run that way,.
As for keeping a inexpensive econobox for 20 years?
the rust will get it long before the engine wears out.
Expect to get a new econobox every 10 years.

Not down south. Can keep an econobox rust free for as long as is desired and cared for.

You are right but the op is from Pa.
As for keeping the same car for 20yrs,? i'd get bored with the same old car after about 5-6 years or 200K maybe if the car was a specialty car i could see it but a plain old Yaris?

[NZ-FE Vios]

Jambo, I'm 24 but this is car 10 for me. I've also had over a yearlong stint of only bicycling for transport. None of my cars were anything special other than that they were mine (all other 9 were cash too).

Seems to me that the purpose of an econobox is to be economical. The longer you have it, the more economical it is for the buyer.

Don't get me wrong, I love my car, but its not fast, and when trying to get good fuel mileage its downright boring. But again that is the purpose of the car. So in my mindset, it doesn't make sense to get bored with a car whose greatest overall purpose is to be boring.

[jambo101]

Cant fault your logic NZ.
I would suggest some form of undercoating/oil spray treatment if you want to keep the car that long ..
