Just read somewhere on another forum about several different vehicles, where they actually do get a fault message relating to auto gearbox overheat after going up a steep hill, is it possible to get it plugged in and see what the fault code is ?? Might be worth a go, as if it is the auto box getting hot, then you are barking up the wrong tree with the other stuff.
Cheers for that, its good to know they all right hand except track rod ends. I am waiting for delivery of the parts(I live in France) will be back in touch when I start the rebuild. I will be getting the workshop manual so I shouldn't need to ask so many daft questions. Thanks for your help and patience so far. Pete
