It could be a problem with the vacuum modulator located on the side of the transmission. It is quite easy to change simply remove it and replace it with a new one. The one thing you will need to do is to take a magnet and remove the internal valve and make sure you change the o-ring. Once this is done replace it with a new one reconnect the vacuum line and you should have no further shifting problems.

ok thank you i will try to do that
