Gary, I think you can find Sta-Lube in GL-4 in most good auto parts stores,
but probably not the big chain stores. I personally like the Redline
synthetic gear lube in my transmission, which for my car gives the smoothest
shifting and seems to minimize the notchy shift between first and second gear.
But it may be harder to get locally. John

My TR6 owner's manual says to use GL4 gear lube in the dif and trans. I
recall a conversation on the list about gear lube and that GL5 is corrosive
to
the copper alloy parts in the transmission. After shopping a bit locally, so
far what looks to be the best I can find is a NAPA product that says it
"services GL3, GL4 and GL5 requirements". I want to take no chances on this
item so I haven't bought anything yet. I wonder if one can even find a gear
lube that is formulated only to GL4 specs. Does anyone have a recommendation
they can make regarding a suitable product I can most likely get locally?
