Is there any difference between the silver coloured and the black coloured hook type seal rings in automatic (727/904) transmissions?

I have a badly worn seal ring on the back of my reactor shaft(back of pump). The old ring looks like a chrome one, and all I can find locally are the black ones.

Cheers

Peter
