Speed sensor nearside front wheel

hi, dont suppose anyone could tell me how i can remove the speed sensor going into the front nearside wheel hub? after i diagnostic i have been told its faulty but may just not be in enough and its causing the auto transmission to hold out before changing. any help on removing it? thanks in advance

It should twist out side to side. But maybe quite tight. If it is put a clip around it and use a pair of pipe grips gently on that to loosen it. When you put it back grease it up and push in until it touches reluctor ring.
