Recently on a road trip my fan clutch ended up dying on me.with this my car tempeture hit 110-115 this happen three times(i would stop and let it cool down) but on the 3rd time i was doing 50mph when i tryed to increase in speed the car started banging and wouldnt get past 65. now i replaced the fan clutch and did a tranny tune up and the car ran good for three days, but now i cant get it past 65mph it starts to bang and at start up there is a good amount of white smoke. any clues on why it not shift and why there is white smoke thanks joe
