I have an 05 Spectra that has been hunting for third gear since about 10k km. Now when it shifts to third is slams pretty hard. Kia is in the process of replacing the trans with only 30k kms. No codes in the ecu. Any ideas out there, anyone else with the same problem. No other posts on the net about this I could find... I can't be the only one with this issue.

DD:

I wonder what KIA did to the tranny and/or programming to cause this in the 2005's?

The auto trans in my 2004.5 EX shifts flawlessly, and it's got 10,000+ miles on it now.

I'll bet they tweaked the tranny's adaptive logic module/firmware for something related to fuel efficiency or something like that for the 2005's, and didn't get something "quite right".

Please keep us posted on here with the final corrections they make.

Thanks,

-SM

Well, after hounding the local Kia dealer once a week (Fredericton Kia) I was supposed to me with the district service manager. He was a no show yesterday morning.

After a few phone calls to the district service manager they decided to "reset" the cars computers by pulling the battery for 10 minutes. Then a specific driving sequence, three standing starts, one easy acceleration, one medium and one to the max acceleration.

The procedure would clear the memory of the computers. Apparently, the adaptive characteristics of the transmission and engine computers get mixed up when trying to deal with certain driving styles over a period of time. For the record, I'm an aggressive driver but not from the rice rocket crowd. I'm 37 and usually have my family in the car so it's not like I'm 16 and dogging it to death.

Initial impressions, everything seems pretty good so far. Transmission shifts much more smoothly. Down shifts to an appropriate get through rolling stops when before it would not. Shifts between 2-3 are smooth and do not slam hard so far.

I've only put about 60 miles/100KM on the car so it will take some time to see if this is a true fix. I think just for the **** of it, every time I change the oil I will pull the battery and run it through the 3 standing start procedure.

I'll keep everyone up do date.

Interesting. When I test drove a Spectra5, I almost killed myself and the salesman because when I tried to make a left-hand turn in traffic, it just kind of thought.... about.... it.... for.... a....long....time before the rpms finally kicked in and it went. I wonder if that comes from the adaptive logic after several different people with varying driving styles drive the car?

I had all but ruled out the Spectra5 but I'm thinking of taking another look. The other cars on my short list include Elantra GT 5 door (which I also didn't like the first time but was much better second time out), Suzuki Aerio & Suzuki Reno. The Spectra and Elantra share a lot of gear, but the Spectra5 looks much better imo.

My tranny only hiccups once in a while... and that is if I am pushing it really hard... going from 3rd to 4th... I think when I get my new ecu (from kfxperformance.com) it should take care of this issue.

Thank you for your post, you are the first person who I know of with tranny hiccups..... is it predictable, can you make it happen or is it very random. I can make it do it when ever I want.

I'm driving a 2004.5 Spectra and it just recently started to jerk really hard when shifting into thrid.. it feels like I'm running over a HUGE rock... I'm not sure if this is the same thing you were dealing with? How did the computer reset work out for you? Have you had anymore problems? I plan on taking the car in sometime this weekend, and I was wondering if I should ask them to perform the reset on my car... I did recently get my oil changed and it seems to have muted the jerk, but it's still not very smooth

Sounds the same as my problem. The reset helps for a while then it start the process of hunting for third. As it gets worse it starts to hit very hard.

They've ordered a new computer for the car in hopes that it has updated software. I doubt it though, I bet the computer has been sitting on a shelf for months and has old software.

Update,

The new computer was installed yesterday. All I can say is, WOW, where did all the hp come from. Excelleration is wicked fast. Top speed has gone from 180 to 200 and still climbing, I ran out of road.

Shifting is VERY good now with only a small bobble when the rev limiter kicks in.


So far so good, I'll update in a few hundred KMS.

It's an '05 so it was warranty from Kia. I'm going out of town for the day, 300kms or so. We'll see if things change or stay like they are now.

400kms since the new computer and all seems wonderfull. Lots of power, smooth shifts and I think better mileage.

Now if I could just do something with this sunburn!!

I have a 2004.5 spectra, from reading above it sounds similar to what mine is doing. When going from second to thrid it will not change gears under WOT (lot of getting on the Interstates), it just hits the rev limiter and starts cutting out, I have to take my foot off the gas, then it will change in to third. Any of you had this happen? BTW the dealership said it was normal with the new tranny in the 2004.5 and up models.

Whether the symptom you described is OK or not, your dealer might be telling you the truth. Same thing happens on my '05 EX A/T. My solution is that I just don't drive like that since there is no solution...

I noramally don't drive it hard, just need it sometimes to get it up to speed to get on the Interstate (short on ramp) and sometimes to pass someone. Should have just got the 5 speed, wife talked me in to the auto, it is her car anyway.

Glad to know I am not the only one with this.
