I know the oil in the diffs and the T/C is pretty dirty. I was thinking of doing a drain and fill on all three but I had two questions.
1) The dealer says I have either a model HF2A or HF2AV T/C in my 1995. One takes a GL-4 oil and the other GL-5. How can I tell which model I have?
2) I have the factory lockers in my diffs. Do I need to include any special additive(s) in the diffs or just any synthetic 75W-90 will do -- I don't do any towing or serious rock climbing at this point. so I assume I can get away with the factory weight of oil for the diffs.
