I did my 4l60e 10+ times with the 450lb scissor lift one... I might have bent it once or twice doing it with the np241 attached.
I used the piss out of that one, finally snapped a guide pin on it.
I'm really shocked I haven't. It's actually been supporting the trans for the passed 5 days.
Apparently you two are actually nunkillers as well
I looked at that one scissor one too, but thought I'd bend it or tip it over trying to wrestle this combo out.
i'm sure it can be available to you after too...
from them too like their sand blasting cabinet
