1988 jaguar xj6 stopped working in any gear. it was not slipping-i was backing into a parking space when it stopped working. i changed the fluid and filter-there was no shaving in the oil pan-help if you can
Other than checking your linkages, the only other thing I can say is it looks like that 20 year old ZF is going to need to come out. The pump is probably out on it. Did it give you any kind of warning such as slipping or trouble in shifting lately??
i did not have any king of problem with it before this
