[6pack] Gearbox lubricant-TR-6

[Bill Wellbaum]

I almost dread bringing up this question but here goes:  I'm having the TR-6
gearbox w/overdrive serviced tomorrow (drain and refill) and am curious as to
the latest concensus of what type of oil to use. I see Valvoline 20w/50 R
recommended often--but am looking for the most current thinking.  Any
recommendations from high mileage owners?
