A change has been made to the Transmission Oil Filter and Seal Kit (part number 24236933) (Fig. 18) for the 6L50 (RPO MYB), 6L80 (RPO MYC) and 6L90 (RPO MYD) 6-speed automatic transmissions used in a number of GM vehicles, including Silverado, Tahoe, Suburban, Sierra, Yukon, Camaro and Corvette models.

The filter (Fig. 19, #1) and seal (Fig. 19, #2) currently included in the Transmission Oil Filter and Seal Kit will now be available individually. The parts being sold individually will help improve packaging efficiencies. To obtain the filter and seal, order filter part number 24236517 and seal part number 24225347. The Electronic Parts Catalog (EPC) is being updated to reflect these changes.

Current service procedures require that the seal be replaced anytime the filter is removed. The fluid pan gasket is reusable. The gasket should be replaced if it is stuck to the case or pan. Be sure follow the appropriate Service Information procedures and use the correct special tools when installing the filter seal. (Fig. 20)

As with the production of all parts, the decision to offer parts kits is based on the resources available to produce the kit in the volume required.
Why would you separate the filter and seal. The seal is to be replaced every time the filter is changed as per service information. This is so counter productive, have the seal with the filter. It also goes for other parts, If requires a seal or gasket or bolts included it with the part.
