got the manual and a set of gauges to check with?
this is a chart from John smith's site. it is listed for the earlier prior models SOS.. but I'd at least read thru it.
the first section about remaining in park or neutral seems a place to start.
there are plenty of SOS guru's here ( not me for sure ).. so they an tell you more. I don't even know if this chart will apply.. but I have a feeling some of it is applicable .
