transmission rebuilt , new problem on 2000 Ford F-350 Super Duty

Just had transmission rebuilt, got the truck back, runs great in forward, but when put in reverse rpm drops down to 500 and sputters then jumps to 900 then falls back down to 700 rpm. With trailer hitched, truck sputters even worse. any ideas?
