It's confusing because the rear drum is the one used for all forward gears, hence the "forward" clutch. But the front drum is used for reverse and third; sometimes called the "reverse/high" clutch, or the "direct" clutch. You might insert the converter for a test. Or turn the input shaft.
I'm getting my new converter Monday, I'll definitely give that a shot. And yes molars terminology of front and rear vs other manufacturers terminology calling them direct and forward confuses lots of people lol.
