Hey guys,

I've been reading forums regarding the VB issues and replacement process and have one question for you. How do you determine if the vehicle needs a VB work or a whole transmission? How would you diagnose it correctly?

So I just got through with this and would like to add a few thoughts.

I put in a whole reconditioned valve body from worldwidespecialityparts.com. We / I decided to buy a "B" code for my 2001 xc70, turned out wrong and we swapped it for the "A". At all times the gentleman Matthew was responsive, pleasant and knowledgeable. I would highly recommend.

I used the procedure from the PDF linked in this thread and precopsters variations on leaving the cooler lines connected to the radiator so that I didn't have to source the green clips. I took it apart with the radiator hose still on, but then changed my mind and took it off, IMHO it's quick and easy to drain the coolant and move the hose.

I also bought the gasket which is probably easier that using gasket goop, however I used some goop on it too.

The good news is that the car seems way better straight of the bat, it might still have a tiny clunk, or maybe perfect and I'm just hyper vigilant about it, also the car was old when I got it so I don't know what perfect is for one of these. But I have way less clunks and bangs. My worst symptom was going from R - D, there was a delay and big bang. That is now instant and quiet.

Neither my dealer or local independent specialist want to have anything to do with this issue. So I haven't taken it for any software or adaptations etc, nor did I do a full flush, just put in 4qts of new fluid to replace what came out. I don't know if really should or not, it seems fine to me, my local dealer can suck it, I am petty and will never go there, ever.

Most importantly, thanks to everyone who has contributed, you have collectively delayed this cars date with the junkyard for a while longer.
