I replaced my flexplate this week. Got the transmission back in and everything connected. When we went to start the Jeep it made a loud click. Did this a few times and it finally turned over and started. Now it starts up perfectly fine. 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?

I was told the starter was the issue because it wasnt retracting after the jeep started. Replaced it with a new one.
Now about 3 minutes after start up, a grinding noise happens right at the front of the transmission.
So now what?

When i removed the starter there were a few flexplate teeth that had minimal damage. Like a tiny chip in them. Just assumed that was from the starter contacting it.
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.

It's seriously about to go to Aamco. This is day 5 of not having a car. I don't know how I'm going to keep getting 40 minutes to school.

Might need more direct exposure on this issue to get others involved. Perhaps start a new thread and copy/paste the details. Specifically about proper procedure for reinstalling Torque converter into transmission.

Nothing wrong with a little professional consultation on tranny issues. Just a double check but are the flex plate bolts tight? Wondering if one of them is loose and backing out as it runs.

Thats what I'm thinking. They'd at least have a better shot at diagnosing the issue.
