i'm interested to know - have you established from testing that the 
lower failure rate is a function of this maint. schedule, or has allison 
changed anything in their transmissions?  and what was the failure mode? 
  metal fatigue for instance is not known to be influenced by oil filter 
cleanliness.  clutch life isn't rally affected by it either.  operation 
tends to get less smooth as particulates ac***ulate, but that's not 
necessarily going to affect overall life of the transmission.
