how are 3500 stall conveters sopasto act

Hummm... Lets see. First the vent is plugged and gets jury rigged to fix it. Now the converter grabs like your dumping a clutch (and of course that's a converter, not anything to do with clutch packs not engaging properly). And now you have a vibration from the B&M flexplate (which don't generally happen). Wow!!! Can't say it enough.

JUNK TRANSMISSION. Sheesh!!
