Subject: Re: Broken bolt on torque converter

From the looks of the head of that bolt, the wear
pattern on it suggest that the other bolts are loose
on the torque converter. I would pull the engine and
make sure of the damage to the flex drive and torque
converter. On replacment get some 8.8 grade
bolts(8X1.25X30mm)and lock washers to replace the
bolts with. Phil.

The installer of my SVX used improper fasteners (SAE grade 5 instead of
grade 8)  Cost me plenty, no warranty support.

So FWIW  M 8.8 is SAE Gr. 5.  M 10.9 is SAE Gr. 8.

I'd recommend the M 10.9, look for 10.9 on the bolt head.  (Cap-Head Machine
