Which year trans and converter and which type trans?
None of the 727 converters I've installed went in easy runaway shruggy
I stand the tranny up on its tail shaft and then align the pump drive teeth straight up and down and then try to install the converter with the pump drive slots aligned with the teeth on the pump scope
Even then I usually have to rotate the converter back and forth a 1/4 to 1/3 turn to get it to drop down both ways, onto the input drive shaft teeth and then down onto the pump lugs wrench shruggy
I have found that the race converters with the 7/16 holes in the lugs need to be down right at 3/4 inch from the front of the bell housing face to the face of the lugs, the converter flex plate side scope
Good luck, you can do this thumbs grin
