Loud clunk

You are exactly right jalodge. I seems like the trans shifts down as I slow down, not enough to slow the Rover (as if I were downshifting to reduce speed) but as if the trans was following the Rovers speed and sometimes getting a little ahead of where it should be. I have driven cars with excessive back lash in the drive train and the SOUNDS like that but if it were that I would think it would do it all the time. I still think it is a vacuum issue or a vacuum valve that controls the trans. Thanks for everyone's help and I will try all of your suggestions before I take it in and let them guess at it.

For those of you who are still following this thread, I think I may have found the problem. I was getting multiple misfire codes also but thought it was unrelated to the clunk. My mechanic said it sounded like the misfires were being caused by a vacuum leak which is what I had always thought the source of the clunk was (trans getting wrong messages). I searched and could not find any vacuum leaks so I took the Rover to him. He performed what he called a "baptism" by taking a jug of water and pouring it over the engine while it was idling. The idle smoothed out and he said I had bad injector seals. He replaced the injector seals and the clunk is almost completely gone and much much less savior when it does happen. I would have to day that now the Rover is normal and I am probably "over listening" for the clunk.
