I was recommended to this site by B_Lieder at turbotbird.com. My Brother has a 94 grand prix se with the 3.1 and his transmission wont shift out of 1st gear. He had a shop check it (he lives in a college town so he called me). They diagnosed it as a shift reactor and that it would cost 1200 dollars all said and done. Ive never heard of a shift reactor. They also gave him the option of a used transmission for $250 to $350, before install. Could it be something else? Hes lucky to afford rent and college so he doesnt have 1200 just to burn, any help would be GREATLY appreciated.
