Changing the auto gear box oil..
Unbolted the sump.. saved all the bolts
Unbolted the filter.. saved the 4 boths
cleaned up.. found in the bottom of the sump a bolt... thought, opps must have dropped that.
But, the sump had 18 short bolts
the filter had 4 long bolts..
there is one medium bolt..
see picture

The bolt with the orange square is extra!
Have I lost my mind?
Looking underneath I cannot see any place it would go..
Please help!
