Re: Gearbox Oil - Overdrives

[Patrick McMullen <pmcmull@ibm.net>]

My personal preferance is a synthetic.

I have used Amsoil 75W-90 in my OD for two years now without any
problems.  It shifts far better then when I ran a straight GL-4
rated gear oil.  Amsoil gear lubes are rated a GL-5 and have
excellant limited slip properties.  The best part is that they are
safe for manual transmissions.  All their gear oils carry the MT-1
rating.  Syncronizer safe.
