Hey Dudes

Question: Ive been driving with the paddle shift recently (I got my car last week) and I noticed something i didnt know about. When you push the car and get to around 5.5 thousand revs it gears up automatically - whats up with that? Because inevitably that exactly when I want to shift and then i end up shifting up two gears...

Am i missing something should i be trying to shift that high? I mean whats the point of manual shifting of an automatic gearbox if its going to change automatically anyway

The transmission will automatically upshift/downshift towards the to ends of the rpm range to keep it from damaging the engine ie. it won't allow you to go passed redline, or to idle too low.

... it's a built in saftey feature, at no charge I might add.

This may be by-passed by a chip, not 100% sure though.

I wouldnt really recomend going much higher than 3500 for the simple fact as stated above you WILL ruin the transmission eventually..

Not much higher than 3500?
Alright grandpa do you just go 25 everywhere and take an hour and half to accelerate 0_o

Did you mean 5500? You can shift all you want -- it won't affect the tranny. Manufacturers wouldn't put the paddle shifters if it meant problems...there IS a 10 year/100,ooo mile warranty and I doubt they would win an arguement that you properly used what they provided...

Well, simply stated you ARE missing the point of the paddle shifters. They are there to make you feel like you bought a high end sports car and as a marketing gimmick. They serve little purpose in the real world other than a ploy to keep both your hands on the wheel.

It's still an automatic transmission in a reasonably priced compact car. It's going to try to save itself from you, no matter what setting you try to over-ride it with.

And I'm hoping you are well out of your break-in period if you're driving around like you claim to be.

Forgive me if I seem a little "stern" here, but people's expectations of the car need to be reasonable.

^^^word! Even the floor shifter on the 2010 Forte's do not let you shift the tranny in an abusive way. You can't get the tranny to shift "up" into 5th gear at slow speeds because the ECU knows it is not optimal for the car. Just enjoy manually shifting your autotranny if you feel so inclined...LoL!

Anyone know if there is also a rev limiter on downshifts on the Sportmatic?
Personaly...I'd rather not try to find out...LoL! If you downshift with the Sportmatic it won't go into first until you are slow enough...but I don't know about 2nd and 3rd. Never tried. Would be nice if it did protect the tranny!

Ya I'm pretty mindful about it since I'm used to it from my motorcycle. It has a rev limiter also but not on down shifts. I'm guessing that with the Forte, it probably won't let you down shift manually at certain speeds to avoid the RPM hitting into red line. It might be in the owner's manual somewhere but I'm too occupied with watching playoff football to check right now :D

not really such a thing as a break in period on modern day cars.

once the rings seat you are good to go and this is done by the factory during a break in/dyno procedure.
only exception to this is new car or new clutch installations on a manual transmission where it is typically a good idea to break in before doing any clutch dumps (though you shouldn't be doing those in a forte anyways)

in my experience running an engine hard the first oil change helps, it promotes better ring seal. i've build alot of high end engines.

Agreed. I've owned built short blocks before with other vehicles. The best way to promote maximum ring breakin is through hard accel and decel letting the engine slow the car down. Under hard accel, cylinder pressures are at a maximum meaning the rings seal to the bores are at max, letting the engine slow you promotes high vacuum which also draws the rings tight to the bores.

But most car manufacturers do this on a dyno before the vehicle ever leaves the plant. So you are good to go.

I have the 6-speed auto, no paddle shifter, but have the auto stick fuction and yeah it shifts when it wants to. At higeways speeds it will not let me go lower than 4th and that sucks as third would be awesome! One thing it will let you do is take off in second and that's nice for when it's slick out.

6 speed auto paddle question

I've had my '11 SX 5 door for 3 months. I use the paddle shifters to decelerate when exiting freeway ramps. The 6 speed auto will also let you make standing starts in 2nd gear - helpful on snow and ice. Manual over rides of the transmission shift points might be better than the transmission's program mode on hilly, curving roads and in anticipation of having to do a quick pass maneuver on two lane roads. For normal driving it's best to let the ECU and transmission pick the shift points since Kia hasn't programmed it to shift too early or wait too long for downshifts. But with the 2.4 liter SULEV engine, the shift action doesn't feel as crisp as it does with the ULEV spec engine. IMHO Kia did a good job on the 6 speed automatic. One source claims they've applied for 300 patents on this transmission.

I agree that Kia did do a good job on the 6-speed auto-I like it alot. I still wish they would have let us have more contorl when in manual mode

like ive said before, a sportshift tranny is NOTHING like a manual. there is no argument to that.

but yes a sportshift tranny is supposed to shift for you, you may be in sport mode but its still an automatic, its not gonna let you push the limits.

I love manual trannys - I have a race-bred miata with a racing flywheel and clutch. I bought it with a the 5spd swapped in place of the 6spd. It is high revving and much fun. It has lots of mods.

Having said that, we really wanted a manual SX Forte5, but none was available anywhere within 500 miles. In my case I am very happy with the 6spd automatic we got. I enjoy the paddles, but more importantly, I have a deep appreciation for the technology going into the design of the 6 spd. trans. The gearing, responsiveness, and smoothness all add up to the best driving experience one could expect out of a budget hatchback.

Here's some more reading about the new 6spd. auto:
