Volvo Troubleshooting Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
I too agree this is most likely the valve body causing this concern. I do have all the repair guides and diagnostic guides. Are there any steps or files you need?
I do not believe I am the best tech for you. I am not good at explaining how to do transmission repairs on this model I am going to remove myself from the conversation and opt out making way for someone else to help.
