so yeasterday i think the input shaft went on the truck. i was i believe in 3rd at about 2000rpm when i droped the tc lockup switch then ther was a huge bang an no power to the wheels. i then called fred swanson(dtt trans guy in az) and thats what he thought to happened. the only odd thing is that i should be able to put it in park and the truck not move but it stillmoves. so now im thinking its the output shaft. but i dont know. anyone ahve anyaddvice. im hoping its the output shaft bc thats alout cheaper9like the difference between 300 and 4200 dollers 4200 with new billet input shaft) please help i miss my truck already :{
