In conjunction with current TSB 16-94-15R, this bulletin provides a new service procedure for
repairing the drive motor case assembly. Previously, failure of the non-serviceable o-rings on the
electric oil pump relief valve located inside the case required replacement of the complete motor
case assembly. Although these o-rings are still not serviceable, a new relief valve assembly, p.n.
31869AA001 (with new o-rings already installed) is now available separately.
