It runs just like normal, but after a few minutes a fairly loud grinding noise is heard right at the flexplate.

I did make the mistake of leaving my starter out in the rain during this because I forgot it was out. So it rained pretty hard and then the starter sat outside for two days. Could the starter be my grinding issue? Or is it something I missed or did?

Now about 3 minutes after start up, a grinding noise happens right at the front of the transmission.
So now what?

Tried something else: started it up, quickly pulled the starter relay, but still had the noise after a few minutes.

Oh and I put it in reverse to see if anything changed, heard a bang then more banging: rear drive shaft u joint broke and it snapped 2 of four u joint strap bolts.

If the starter stays engaged or does not fully disengage it would immediately make noise, not this delayed reaction.

To bypass the c101 ???
