It seems fine after I have driven a couple of blocks. Filter & fluid was changed this summer - perhaps 2500 mi ago. No metal shavings in the old fluid. No burnt smell in the old fluid.

I haven't checked this week but vacuum measured at 18" or so the a month ago. There was a leak on the line going to the passenger side front. The line connects to a valve which also has an electrical connection. I think it has something to do with the EGR system but I haven't tracked it down in the FSM.
