There the three engagement points, but no clicks. You first get the input shaft spline, then the stator shaft splines. These go in very easy. The last would be the pump hub into the pump rotor, that can sometimes be a challenge depending on manufacture of parts. The converter will bottom out on the pump rotor at which time base of converter hub should be almost against seal and should not see the converter hub. This would be seated all the way into pump rotor. Some converters are built off spec and this could change a little. Machined pumps can alter this also, but you can feel it bottom on rotor. After installed, check clearance from converter mounting pads to flexplate. It should be .125" to .188" spacing. If more shim to get the proper clearance in that range. I recommend as close to .125" as possible. Any questions feel free to contact me.
