Thanks Peter Yes the rebuilt Auto trans and change over T/C was running behind the 3.9 and I have already checked the thrust bearings they have a small amount of wear but all within allowable tollerances. I think the thing must have started going bad after the 4.6 was fitted. I am contemplating finding someone that can test the auto and T/C to see if there was something amiss. As for trying for a claim through the auto/trans rebuilder it's probably not feasible as the warranty period has well and truly lapsed even though the rangie was off the road for twelve months whith the start of that period being only six months after it was rebuilt. Yep I know of Ashcroft's I might give them a call and see what they have to say. I know that I have not done anything wrong myself to cause this failure but it's all pretty much academic now. Thanks for your support Peter.
