Was in an accident a few months ago - hit the kick down a wee bit too soon when leaving a round about and car went into a spin. Engine revs went very high and wheels spun taking me into a 360 degree spin.

Engine revs remained high throughout spin. I now seem to have a problem with the kick down - when applying kick down and keeping foot to floor - drops gear ok but then sticks at high revs and does not go up through the gears (unless accelerator pedal is de pressed). Normal automatic gear change is ok and tiptronic also works ok - only have a problem when kick down is applied.

Trying to asvcertain if original accident could be the cause of this problem ?

Would appreciate any advice.

Thanks
Stuart
