starter grinding

Think about this for a second. When the transmission is mounted to the engine, the converter (bolted to the flex plate) is supported horizontally by: The pilot on the converter into the crank flange, AND the hub is supported by the transmissions pump. With what you're doing now , with it mounted just to the flex plate, the hub has no support at all. And I personally don't see mounting it to a B & M or any other flex plate will cure the problem. JMHO and others may not agree.:canada:
Ok, I tried lifting the converter by placing a piece of pipe in the drive hub and prying up, to take the weight… converter didn’t move at all….B+ M weighted flex plate behind the converter doesn’t have much “flex”…and powering the starter while prying up makes no difference… grinds the same. The hub has Pat Blais’s converter ring on it as well.
