I was taking a back hand to the people that are prescribing service based upon marketing factors.
It seems that the concensus of techs are recommending the lifetime fill trannies be serviced at 50-60k. A subgroup says that if the trannie has not been serviced by 90k, don't touch it. This warning is among techs to prevent one from servicing and winding up married to the very possible driveability problems that can result from such service (after no service).
