I've got a stock P/G case that came with a car I bought. It has the hole for the band adjuster bored slightly over sized. Still has the stock threads, but down in the case the hole is larger, all the way through, than another stock case I have compared it to.. It has a rear roller bearing, too.
I was told it had a harder over sized adjuster rod for high apply pressure on the low band. Have you ever heard of such a part? Who sells it if you have? I hate to scrap the case because the rod moves around too much.
