Checking the Shell 2010 lubricants handbook against an older 2005 edition, T1 and T5 are still rated for hydraulic transmission duty making them suitable for wet clutches. The T5 is the new name for Rotella synthetic and the T1 is the new name for the old straight mineral oil. T6 has the antifriction additive that makes it unsuitable for transmission clutches.

Did Shell drop the Rotella T Synth???  I've always used this in my GPZ, and
my fiancee's EX250.  I couldn't find the stuff anywhere today.  I see they
have new lines of Rotella now.  T1, T5, T6.  Anyone know if any of these new
lines will wreck the clutch?  I miss my simple choice :(
