Hi recently my 5 speed auto went bad so I had a reco put in and after 10,000km now this one went the same way no drive or reverse just free reving and my warranty ran out 3 months ago, so my question is what will be needed to convert it to the zf box my fg has 175xxx on it and don't want to risk over 2k on another record for it to go again In possibly another 10,000 km
