 It is my intention to change the oil in the transmission and front

  If so, are there any distinctions between Redline and Castrol?

 What weight would be appropriate for ambient temperatures that range from
 -20 F in the winter to 95 F in the summer?  Would 75W/90 be best?

 What is the capacity for the Syncro 094 transmission and front
 differential?  (I have perused my Bentley without success.)

 This oil change is scheduled for Monday, so quick responses would be most
 helpful.

 The best synthetic oil for any transmission would be "Sweptco" (not sure of
the spelling).  It's around $30. a gallon, but worth every penny. This stuff
is magic. I'll will post the phone number when I can find it. Michael M. 87
