hi guys my family wagon is a vy 2002 ss 5.7 auto,the gearbox has reverse,1st and second gear and then slips(free revs),so I have been calling around and the experts tell me it is a common problem that the clutch package for 3rd and 4th gear fails on these models,they say I have to pull the box,rebiuld it for around $1800,then they say I have to go to holden to have the soft wear upgraded so that it wont happen again,dont know what that will cost?whats your thoughts?anyone herd of this before?
