Torque converter install.

[SV13]

I’m putting in a 93 engine in my 90 2wd auto pickup. I accidentally removed the torque Converter from the trany. I for the life of me can’t get it back on. I’m pretty sure I’ve moved the splines on the input shaft. Do I need to get an alignment tool. 
I’ve been at it for three hours now. 🥵

I haven't done your particular job, but I think you have to line up two items - the splined input shaft and the tabs (or cutouts) for the pump.  Usually the shaft engages first (could be the opposite), then you need rotate the converter (with no axial pressure) to find the tabs for the pump engagement.  Just an educated guess.

Thanks for the reply. My trans has two shafts. An inner and an outer. The pump drive is easy to see to get the notches to line up, but I can’t get the torque converter on far enough to engage.

When I have a hard time lining up a convertor, I set the transmission into a vertical position and lower the torque convertor on to the shafts, spin the convertor and let gravity pull it into position.
