Information
The 6L50 (MYB), 6L80 (MYC) and 6L90 (MYD) Transmission Oil Filter and Seal Kit part
number 24236933 is currently transitioning from a kit to the filter and seal being sold
individually. This is being done to improve packaging efficiencies:
– Filter Part Number 24236517 and Seal Part Number 24225347 will need to be ordered
separately to obtain both pieces.
– Current service procedures require that seal be replaced anytime the filter is removed.
– The Electronic Parts Catalog (EPC) is being updated to reflect these changes.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
