600012 GM 700R4 12" Torque Converter 2200-2400 Stall 30 Spline

I'll start with it was supposed to be a 30 spline (replacement for 700r4 stock converter) (Yes I did count an verification with original number an part on stock one) I added trans fluid like you do to a torque converter before you put it up. Went to put it on the input shaft nothing lined up but took 30 45 minutes nothing worked went to send it back to get a refund obviously because they had the wrong splines they said they can't sell it as original and it looks like I attempted to install it (duh isn't that what you do when you buy a part to put on a car install it). I can't give less than a one star but buyer beware. They sent wrong part an blaming me. An only got half what I paid for there mistake. No stars from me if I could.
