4l60e problem
 

i tried running a search first and couldnt find anyone with this same problem so here it goes. i was driving down the road after just starting my 97 blazer and it just lost all gears. there is no responce to any gear except park. before this happened there was no warnings there was no slipping, grinding, or shuttureing at all. i checked the shifter linkage and its fine. i checked the fluid and its a nice light red with no burnt smell. i got the tranny about 2 years ago with a fresh rebuild from the prior owner. i put on a new valvebody and soloniods, a deep pan, and a b&m shiftkit(since i allready had them laying around). i dropped the pan off this morning thinking maybe the filter dropped off makeing it lose fluid pressure and to my findings there was little metal flakes in the bottom of the pan. iam thinking maybe the pump or converter. any ideas? thank you.
