Well i installed the new raptor tranny and TC i got from another member on here. Im pretty sure the tranny is ok, it however has no gears at all. I was on the gas pretty hard at about 5500rpm's, when it made a loud pop and went into a neutral. I stopped and it has no gears but its not throwing any codes or lights or anything on the dash like the old 4l60e did. Its also not leaking anything either. so im not real sure but im hoping the TC came apart or something. Its a 2500 TC. Im thinking that the fella who put it in didnt have enouph oil in it. were gonna get it back out and take a look tomarow. sorry about the long post
