So in your opinion, GL-5 ok to use where GL-4 is required right?

GL-5 does not cause spalling on steel (note the EP rating). GL-5 actually
protects steel better than GL-4 because it has extra additives that form a
chemical layer on the surface of the steel, preventing metal-to-metal
contact better. The only reason not to use it in manual trannies is the
corrosion of bronze.
