GL-1 90W gear oil...confirmed...

[Plymouthy Adams]

For those folks with lube need for their standard three speeds and the OD unit this is the proper API GL1 that you need.  Again, for transmission and OD's 

 

I have always pushed that the members here use GL-1 and as I never had a stock tranny/OD I never gave it any concern personally to look for it..but last evening I discovered my Toploader four speed in the Tiger needed topped off. 

 

Appears that the least you can buy is 1 gallon but for 14.00 how can you go wrong?  source;   NAPA

DO NOT USE IN THE REAR END..THIS LUBE NEEDS THE EXTREME SHEER PRISSURE PROTECTION PROVIDED BY GL-5

Tim, this Wikipedia entry verifies what you are saying. (Assuming you can trust it) I had been wondering what to use in my OD.

Thanks for posting.

This is what i used in my 3 speed transmission. However it is very thick when cold (below freezing), need to let the truck warm up for at least 10 minutes and then the gear shift moves freely again. when its cold shifting gears is like mixing peanut butter !!!
