      With that new of a car the computer should not have allowed the transmission to engage in reverse gear if the car was moving forward. There are safeguards built in to protect the car from that happening.

      Most newer transmissions have a override protection inside so you don't do damage or grenade transmission. Wouldn't worry if there were no unusual noises that occurred when you accidently selected wrong gear.

      See what the code is for. It is possible that the accelerator pedal position sensor located in the accelerator pedal assembly could have gone bad. Report back with codes and mileage.

    New front wheel bearing...
    just had new front wheel bearing pressed in at napa,when we try to slide it in will not go but flip it over hub side first backwards it slides right in,could the center spline part have been pressed in wrong??

      Check the lead-in edges on the axle shaft spline, and on the hub bearing spline - be sure there are no raised surfaces or damage.

      Deburr (carefully) the leading chamfer edges for both parts and to insure the splines will mesh together - using a fine grade file and crocus cloth. This may require several attempts - be sure to use patience with the deburring - just enough to achieve a slip fit.

      Or use the axle spline itself to "push" through the slight damage at the beginning splines when you slide the hub on backwards. This might be quicker than filing and trial and error. If the axle is able to engage the hub backwards for like an inch or almost an inch and then it stops, a small hammer with careful stikes will "clean up" the damaged spline. Been there done that.

    Transmission slipping
    Automatic Transmission: While driving down hill take foot off of brake and put on gas - car drove like it was in neutral. I slowed down and manually put car into 1st 2nd 3rd - then to drive and car shifted fine. Has twice happened to me.

      First step - check and refill the transmission fluid level as necessary. Once the fluid level is OK, check the condition. If still 'slipping' then time for further testing, up to and including transmission rebuild or replacement

      Transmission fluid level was fine. Some people are telling me to have the transmission fluid changed and flushed (I bought the vehicle used - the fluid has NEVER been changed); while others say this will only cause me problems as the vehicle has 200K miles.
    • Jimm

      The transmission fluid and filter should be changed - even if never done previously. It is a gamble - there may be no problems. However, if the fluid and filter is not changed at some point, then you can bet the transmission will not last.

      The transmission is not going to fix itself with the slipping going on. It already has a problem. Occasional slipping is not an acceptable situation so you have to do something. The worst that can happen is the fluid and filter change either helps it or makes it worse. I vote to change the fluid and filter because if you don't and you just end up spending $1800 to have the tranny rebuilt you will always wonder whether you could have avoided that expenditure because you didn't try.

      According to the Kia service dept., this make and model does not have a "changeable" transmission filter - it is the wire type that is internal. Does this sound correct to you? Also, I have been told to use Mopar 7176 or ATF + IV transmission fluid INSTEAD of the cheaper/regular transmission fluid - is this correct?

    Car Vibration while driving.
    Car Vibration at about 50mph and again at 80 mph, the vibration first started with braking but not anymore now only while driving, all break pads and disks are new so that is not the issue. Mechanic mentioned that i need the UJoints for the drive shaft? Please help.

      Yes the driveshaft issue sounds plausible.

      If have a very similar issue with Kia Sedona '02. At first it was worse at 78-80 mph. Pretty much went away after tire balance and rotation. Now between 45 and 50 mph while accelerating, there is a vibration and reduction in power. Goes away immediately if overdrive is turned off. If I then accelerate past 55 and turn overdrive back on, it shifts cleanly. Sounds to me like something in the transmission. Thoughts?

    Overdrive Question: A message on the dash says "OD Off." I have pushed the button on the shifter but no change.
    It is obvious that the automatic transmission will not shift into over drive. This is a real problem on the freeway!

    My air conditioner comes on cold for 5 minutes, then turns warm. So mechanic did the freon service but it didnt change.
    They also did a diagnostic and said my car is overheating and fan running full time. They said I need timing belt service. Then they said I have a transmission problem but I don't have any issues with that. They said I wouldn't know but the diagnostic shows it. ...

    Why does it sound as if I'm still trying to start the car when I press down on the clutch to shift into first.
    Mileage-130,000/ After I have started the car I press down on the clutch to shift into first or reverse and it sounds as if I am trying to turn the car on again after it's already on. This happens whether it's cold or warm, and only when I first start it. It is ...

      Are you saying the starter is hung-up on the flywheel? Check the starter and flywheel. Check starter wiring circuit. I haven't looked at your wiring, yet. There could be safety issues testing at the starter, safety is your responsibility. With the vehicle running, shouldn't be any issues. Tranny in neutral and functional parking brake set.
