Kia Spectra/Spectra5 Transmission Questions
If anyone with a 2004.5/2005 Spectra experiences any shifting issues
with their transmission (esp, from 2nd to 3rd under heavy throttle) there
appears to be a known problem with the transmission's computer/brain.
It has been reported on another KIA Spectra forum that KIA has replaced
the transmission logic module on some poster's cars.
It appears that this problem is fairly rare, but it has been reported
by more than just one person. One person's experience was for the dealer
to reset the transmission's program by unhooking the battery, and then
having the owner run through a slow/medium/fast driving regimen This
helped the person for a short time, but then the problem reoccured. KIA
replaced the transmission's computer and the poster reported that their
car acts completely different... for the better!
My 2004.5 car's AT appears completely fine, so it must be an isolated
issue OR a problem that began after a later programming tweak in later
2005 production (perhaps after some programming adjustments to help
improve the Spectra's gas mileage???)
The 2006 model supposedly is getting a whole new transmission design,
so time will tell how well it works out.
So, if any of you experience any problems with your AT be sure to tell
your dealership that KIA's aware of the problem. There may even be a
TSB for this in KIA's warranty/repair computer system.
