mine went out like that in jan.. i didnt get the flashing tranny light or any warning just driving along and it went out, i figured the fluid wasnt getting thru the screens to the axles, i crawled home in 1st.. clutch pack or troque convert material comes off and clogs up the screens.. i had it in the dealer a 10 days earlier for a tranny flush they have always done the tranny fluids and on time.. they said the tranny was fine at the time..so they just go out.. its a 92 auto.. its normal to have some metal shavings on the plug its magnetic.. the dealer put in a used on they found it..1 yr warranty..
