Hycar Gaskets

In the parts list there are two types of Ultramatic gaskets: normal and Hycar.

Example:
3.508 ULTRAMATIC - GASKET SET-ULTRAMATIC TRANS
3.509 ULTRAMATIC - GASKET SET-ULTRAMATIC TRANS HYCAR

What's the point of two different types of gaskets?

Hycar is one company’s brand name for nitrile rubber. Compounds made from it will have better oil resistance than most other gasket materials

True, but any thoughts on why that would even be necessary to offer two types?

Speculation, but not developing leaks after a while due to gasket deterioration? The nitrile gasket is a higher part number, so running change?

Being different group numbers means they were different parts rather than a variation of the same part.
