Threads on the captive nut at the right-side end of the transmission mount are in lousy shape.  I tried to tap out the hole but it still looks ugly, and the bolt  won't go in smoothly. I don't think I've got much left there.  So my question is if install hel-coil, will it be strong enough to withstand the torque of the transmission?

 

Many thanks 

Heli-coil is really only a temporary fix, do it right with a Time-cert and never think about it again,  you might also want to replace that bolt with a new one if it is chewed up.

Thanks Granny (as always).

The new bolt was always in the cards.  8.8 grade and bigger head (yea I know, it's not original, but who else is going to be crawling under the tranny?).

"Time-cert" is a term I'm not familiar with, but will be looking it up asap.

Best regards,

I haven't used Time-serts in the past but I have used Keen-sert inserts. They're made for high strength joints in low strength materials, like aluminum transmission housings.
