Is (GL-3,GL-4, GL-5) ok or do I need ONLY GL-4 gear oil?

Getting ready to do a clutch job on my G20 and went to Advance Auto, Pep- Boys, and NAPA and All I could find was:

work with GL-3, GL-4 and GL-5

on all of the bottles.

NAPA does carry a GL-4 ONLY that is 85W90 gear oil, but I thought ours were either 75W90 or 80W90. Would the 85W90 be ok or am I aslking for trouble.

I am not really interested in Redline MTL or MT-90. This is a stock replacement, I am price conscious and I am looking for a standard gear oil.

Any suggestions would be great!

Anyone?

Just need to make sure the 75W90 and/or 80W90 that is stated for GL-3, GL-4, and GL-5 is ok to use in our trannies.

Yeah, you're good. 75W90 and/or 80W90 that is stated for GL-3, GL-4, and GL-5 is ok to use in our trannies. I actually just did my gear oil change last weekend with great results. I used Redline 80W90 though. Much smoother shifting but I think it's because no one has done a gear oil change for a long time.

Just make sure that there is no sulphur content in the oil or it will eat up the synchros in the gearbox.
