    How many miles mate? Could be the fluid is low or needs changing. What are the gear changes like, does it bang around at all?

    I've seen a lot of contradicting things about the fluids in these boxes, but I think it should be changed at some point but I don't know when!

    Sounds as if it could benefit from a fluid change.

    Not got my head screwed on right at the moment at the moment but I am happy to write out some instructions for you later on?

    Check the how to sections though I expect somebody else has done this here and written a guide already.

    try to replace oil (filter can be changed only at full service gearbox opening) and maybe check for soft update for AT & ECU!
    For other users- how is Yours opinion wuth AF 40 gearboxes? is some typical problems knowed?
