Reprogramming the transmission control module with the latest Kia transmission software may fix abnormalities in the automatic transmission and erroneous transmission-related Check Engine Light illumination. Software updates are commonly most effective on newer vehicles. Higher mileage vehicles may exhibit a similar symptom caused by a component failure. However, whenever major transmission repairs are performed the transmission software should be checked and updated as necessary.

    TRANSMISSION WILL JUMP WHILE DRIVING, TYPICALLY WHEN STARTING A TRIP, ONCE TRANSMISSION JUMPS IT STAYS IN 3RD GEAR AND WILL NOT DOWN SHIFT. I CAN STOP THE CAR AND RRESTART AND THE PROBLEM SEEMS TO GO AWAY.

    I recent just had the vehicle Speed sensor replaced for $180. Ok for a couple days then driving down the rode only a couple blocks from the house and about 35 m.p.h. the engine does a severe downshift and I hear the "check engine light" come on. I had it checked at Auto Zone which said it could be low fluid, ...transmission failure. Checked the fluid it was way over max (I had just bought this Sedona 3.5 van). Anyway I removed 5 quarts of a very contaminated fluid; remove drain pain plug with 24 mm. I added 3 clean quarts back to a normal level. removed the neg cable of the battery to reset the code to an off position. Started the engine and check light returned within 2 minutes but no downshift. It's going back to the shop that put the VSS in it tomorrow. Note: there is a recall on these cables that may help us. I'll report back my findings. Note #2-I read if a VSS is replaced their must be a factory update to the computer or the above can happen! Stay tuned!

    Transmission kicks hard once you stop after getting off the highway.

    Car jerks going up hills and sometimes when taking off from dead stop. Have to put foot heavy on accelerator to get car moving smoothly.

    Transmission locks and makes a grinding noise like metal being dragged across the pavement.

    Hard down shift to 3rd and wont come out of 3rd. Stopping and turning off engines resets it and may not dot it agin for months but again it might do it the next day.

    When I change from park to drive or to reverse position, I hear and I feel a big "toc"in the transmission, but that doesn't keep it to operate, work, properly.

    check engine light stays on, but mechanic says one of the four o2 sensors was replaced and it has to drive several hundred miles to align with the other three and not be seen as the bad one...for sensor to re-calibrate itself and be acceptable to the computer.
