how can i repair my bmw 330d gearbox?

Problems with these boxes is not very common. Is your gearbox SMG or steptronic SMG versions have paddles on steering wheel to change gear and is basically a manual gearbox with hydraulics to shift gear.Whats the fault symptoms?
Would suggest getting a 2nd opinion from local independant(BMW if poss) garage.
The diagnostics on the tiptronic box is very good when connected to the relevant hardware bmw-dis or the autologic systems used by some independants can tell if its electrical and/or mechanical. if electrical can be sorted fairly easily, if mechanical a good reputable autobox repairer MAY be able to repair cheaper than the price quoted. If new parts needed try specialist breakers yard?
