Hi Guys,
I was wondering what weight and GL-rated oils are used in the MR 6-speed tranny? I'm trying to find out if Pennzoil Synchromesh (GL-S) or BG synchroshift can be used ... Also since the 05s have a helical LSD in front are these oils even safe to use? I'm looking for something that will enable the synchros to work a little faster ...

Thanks
Suraj

GL-4 for the tranny and GL-5 for the TC/Rear Diffs
