What does Transmission control do when not working?

Thats a vauge question there are a endless number of things that could happen.If only it were that easy to diagnose a bad computer.Lets start with what is your car doing?

Well started didn't turn and well the owner put negative with positve to pass energy to the battry after the car made real bad gear changes, well after that the car turns off, when you try to turn it on it does but you put on the 'D' is car shakes it run very slowy and going to like a real small hill turns off and only makes it to fist gear and turns off

So when they jump started it was the polarity switched?Also did you have the battery and alternator tested?Made sure the battery cables are clean and tight?

Did you check all the fuses and is the MIL illuminated?

Battery good and alternator is good,yes I checked all fuses, and no is not on.

Even though the light is not on i would still check for codes.

I will I'm taking it to Kia to tell me what's wrong. do the codes tells you that it could be a trasmission control?

The codes are starting points for diagnose there are a couple of codes here and there that will say to replace a computer if the code sets.But thats not the norm you have to get in there and elimante everything else untill nothing else is left to find a bad computer.Thats what i do before i even think about a bad computer could be causing a certain problem.

I would think this is more of an engine rather than transmission fault.

What scares me is they said this happened after a jump start.The first thing that comes to mind for the power being so low and not shifting is a plugged cat.But that shouldnt have started after a jump start.A bad alternator or battery came to mind too but they said that tested good also would make sense for having to jump start the car.

Sometimes the information we receive is not what it should be so couldn't be helped if we get the thing wrong.

That is so very true.

I went to autozone told me both were good, but the problems started after the owner put the negative with postive cables to the battery, I took it to one auto mechainc told me gas pump he said it was good after checking other things told me the values are bad and have diffrent readings, I went to a second auto mechainc told me the same the gas pump he checked it and said it was good.The resond I think is the trasmission control is because after puting the cable wrong the problems started with the gears to be bad after about 2 weeks the car the car faild and it only turn on shakes when I put 'D' and runs really slow after almost going to 2 gear turns off.

Sorry for the wrong information at the first question. I know it makes no sense to jump start, but I jump started it when the car didn't turn on then having an accident with the cables,after that I did take the battery and alternator to auto zone to check and tested good, I hope this information helps now.

Thats what i asking from the begining if you jumped it backwards.That can damage a computer or if your lucky blow some fuses or fuseable links.

Well they checked the fuses but not the computer I'll have that check Friday.

Alright keep me posted.

They gave me these codes P0650, P0028.

P0028 = Intake Valve Control Solenoid Circuit Performance.

P0650 = Fault with the MIL. Is the MIL showing when ignition switch is turned on?

No Because one of the mechanic erase all the codes, kia also told me that the repair is 3,000+

If the check engine light isnt coming on when turning the key on you have a bad blub circuit etc.What did they say they were fixing for 3,000?Did they look at the car to diagnose it?

Yes they did they told me this both manifold converters and catalytic converter restricted

I was saying a plugged but you said it started right after your jump start.So you have a 2.7L engine?You dont live in california?Did they say what took out all the cats?Thats odd for the cats to fail at the same time.I would see if a exhaust shop can narrow it down to certain cat.Sounds like there just doing them all.Also looks like they just bolt in so easy install no welding.If you dont live in california you could get all the cats for less then 1500 and put them in yourself.

I know I checked on ebay and the total cost is about $1300 for parts and I have a friend that could do that for me for $300.

Yes is 2.7L and I don't live in California.

Look on www.rockauto.com check those prices and copy and paste the part numbers on amazon and see where the best price is.

These prices are very low thank you!!!!!!

Your welcome what was the total you found from the site i sent you.

Huge diffrents 924.19, and auto ware house was 1152.19

Cool that will help off set your labor cost.

Yes it will hope every thing goes well.

Please let me know how it works out.

I will.

Is not working out really good :(

What happened?
