Gear Lube 2

[ShewFamily@aol.com]

Has anyone on the list had experience with a product made by Pennzoil and 
carried by Autozone that is a gear lube made for some GM and Chrysler manual 
transmissions?  It does not have the designation GL-4, but it explains that it 
is specifically made for syncromesh transmissions and that it will not damage 
the copper or bronze parts as the GL-5 fluids will do.

Thanks.
