hi all, my 2004 vogue td6 l322, auto box seems to be melting, its the gm box about 110k done, today flashing is, trans, fail safe mode. keeps coming and going. hard to pull away as if clutch slipping, takes over 4k revs to do 50mph, slight judder coming to halt. the engine is running lovely, doesn't miss a beat, is it time to think its had its day, or is there any little common faults to check first, thanks guys
