You really just have to keep working it until it slides all the way in. I've never found any trick...its just patience. Seems like it takes me about 10 minutes to of wiggling to get a torque convertor on every time I mess with one.
This is one of those items in which I think "the other guys" had a better idea: Bolts through the flexplate into the converter, rather than fighting to pull the converter-mounted studs through the holes in the flexplate.
Anyway, I found that my Nail-Puller had just the right bend to reach behind the converter (through the starter opening) and leveraged it forward. Not sure of the officially recommended procedure but I'd suggest torquing the nuts in several stages, criss-crossing as if putting on a wheel. Good luck.
ditto on the patience. Put one on yesterday and could not conceptualize the method with the
equipment. As an exersize, after it dropped on I marked the placement and pulled it back out.
Close examination yielded no clues. Then I dropped it back in..lined up the marks...it did not drop!!!
Usually it is 2 clicks then a slide for installation. The 2 clicks occurred with minor wiggling.
Slide occurred about 45 degrees off after about 7 minutes of turning and jiggling!!
Ronny Milsap was singing "Let's take the long way around the world" on the radio so I was
having a good time.
Put the shift lever in the Park position before trying to seat the torque converter. Of all the ones I've ever done, I think the only one that took me over 15 seconds was when I was trying to seat a '66 converter into a '70 C4 (and THAT ain't gonna happen! *LOL*).
