Be careful with the GL-5...
Look at the label and check to see if it says something like: "safe for modern synchromesh transmissions"
Else, smell the stuff!
Sulfates is going to stink like rotten eggs and burn your nose.
Gear oil without the sulfates don't smell like that.
If your synchros are already on their way out, old trick is to run heavier gear oil...
Running the same (or close) viscosity oil is most likely not going to help at all.
Since the recommend oil is (I think) 75W90, go heavier...like add some 85W140?
The heavier oil just makes everything work slower, so this helps the gear changes and failing synchros.
