You don't want any stall converter with 2.56 gears.
Been on several Pontiac sites for about 5 years or so. Never heard anything like that before.
So, please explain why you think a stall converter should not be used with 2.56 gears. ???
Maybe he means you should have a manual transmission with that rear end?
