I've got an 85 GL  w/ A/T.  I changed the fluid and filter in the main pan shortly after I got the van but I was wondering about the gear box behind the big  pan  ( closer to the engine)  I think it is the final drive if I am not mistaken.  mine seems to be leakin a bit.  Now my question is this.  Does the final drive use the same resivior of oil as the main pan or is  it separate?  If it is separate do I use the same fluid as the other and do I fill through the plug on pass. side?
