I have an 04 Vivaro and had 2 gearboxs ftted, I have heard the latter models are a different gearbox which is good to hear, not good to read a reply on this post saying they still have major problems with the newer gearbox.
maybe Vauxhall still has to prove a point, althouh my Vivaro is running great now ( fingers crossed ) after the fearbox going TWICE I would be very wary buying another.
