HELP- with installing a torque converter -727 trans .

That video is definitely telling me it was not in far enough. I noticed the old converter had no weights on it(383) THE Mopar in my brain is coming back to me from my 318 vs. 360 days. )- this trans & converter came from a cast crank 440 so I guess I should knock the weights of the outside too-
ANYWAY- I measured inputs just to be sure and noted the NOTCH in the converter is .600 in the old converter & trans and only .400 in the replacement trans & converter. thanx so much Crossy.
