change the transmission fluid and clear the code and it should fix it.


No there is problems shifting


if it doesn't fix it you could have something going on that could lead to the transmission failing. when you change the transmission fluid replaced its always good to replace the filter inside the transmission. if it hasn't been changed from the factory, then its most likely starving itself of fluid


is it shifting hard or not shifting at all

So where are they fuses


So where are they fuses


Can u tell me which fuß it is


the fuses are usually under the dash on the driver side. usually with a cover over them. i don't know exactly which one it is, you can pull out each one individually and check them for burn marks. if they are still good replace them in the same spot, otherwise you can end up messing up more than one fuse.
