My car is a 1955 Clipper Custom with the 352 V8. The engine is presently out of the car; I am having difficulty installing the torque converter on the Twin Ultramatic. The converter engages the splines on the shaft coming out of the transmission, but despite many tries and much rotating and jiggling of the converter, I cannot get the other 2 sets of splines (those on the converter) to engage. Is there some trick to doing this, or is it purely a "try until you get it" kind of thing? It's hard to picture a mechanic at a Packard dealership sitting there for a couple of hours (which I did) trying to get the converter seated.
