WhiteTee - right on the money there - looks like one of the bands was slipping so its been shimmed and things are much better for the time being - eventually it will need an overhaul - guess that will depend on how I drive it.. Blokes at CNJ were really accommodating, they use a crew at Underwood who do the mods so took me around there and they took it for a spin... initially thought that it might be low on fluid but after a look could see where the band had been slipping - an additional 1.5mm tolerance to what it should be. This being said - with only around 30,000k's on it, in hindsight I should have had the bl00dy thing done under warranty prior to having the mods made, obviously the belt was already loose... so there’s the moral to the story - If you’re going to get the trans modified, suss it out first - if there is evidence of belt slip - get that sorted out under warranty first - then do your mods... nothing like hindsight.....
