In my earlier post I was having a knocking or ticking noise in the torque
converter of my 700R4. Well, I removed the torque converter from the
transmission and found that the neck of the torque converter was broke. When
I say neck I am referring to where the input shaft from the transmission
slides into the converter. It has 2 notches in it and half of it is broke
off. I recovered the broken piece and there does not appear to be any marks
or rubbing that may have caused the break. The transmission was working
fine, it just had a knock in it. The transmission is in a stock truck that
is never run hard. Any ideas of why the neck broke?
