I have owned my monty for 8 months I don't know if PO put GL-5 or GL-4 in it, as well as the fact as since the monty is 23 years old the odds are great that someone along the way dumped in some GL-5.
Thanks for the info on refilling, will do.
I'm going to replace fluid, and then clean up all the wet underneath. Drive it a bit and see if I can locate leak.
