I think this fell out of the front pump on my '66 C4 while I was rebuilding the trans. What is it and where does it go?? I don't see it in any schematics.
Someone told me it was used to prevent TC ballooning in high temp/high rpm conditions and only in '65 and '66 C4s. Can any one confirm? I still don't know where it goes exactly, but this person said you can run without it.
