my 95 a4 z28 accelerates fine at WOT but when it gets to the redline area it doesn't shift, shifts any other time just not at WOT after it hits redline, i've taken it to a trans shop they say the trans is fine its an engine problem, some people say its the tps some say i need a trans flush and filter change im getting both done tomorrow but i wanted some feed back before i go in case its something more then the tps and flush/filter what do u guys think is the problem???
