Rebuilt 5r55w lost drive & reverse

[ROBERTB34]

i have an 02 MOUNTAiNEER with 6k miles on rebuilt tranny. suddenly drive and reverse slipping extremly bad. can put in low and pulls fine. pulled pan found magnet covered in a sludge. low/rev servo piston housing was seperated ? ohms checked ok on solenoid pack. put sevo housing back together and reinstalled and replaced fluid. still slipping in drive and reverse.
thanks for any suggestions

Take it back to the rebuilder, I would hope it at least had a 12k mile warranty.
