2005 Corvette - Transmission Issues Continued
So we are continuing to diagnose our 2005 transmission issues, and all of the electrical issues seem to be fixed with checking all the connections, changing a wiring harness, and a solenoid. But....yesterday when he was changing the wiring harness in the transmission, he found pieces of a broken spring in our transmission fluid pan. 
What would cause this? The car was fine until all of the electrical issues started, and then it snowballed from there. Can the electrical issues that were affecting the solenoid then cause something to seize up in the transmission, causing the spring to get in a bind and break? We have 1st, 2nd, and 3rd gear. He's hoping it won't be a complete rebuild. I am very confident in his abilities. I'm just really trying to wrap my mind around how this could have happened. We have about 79,000 miles on the car. It doesn't seem like it should be having these issues yet.
Thanks!

I hate to say it but its probably going to be a complete rebuild. 4l60e's are notorious for coming apart like this. Make sure you send off the convertor to be cleaned as well or you'll be in the same boat in a few months.

Thank you for the info. He is supposed to call us Tuesday or Wednesday to let us know what he finds.

According to the Carfax, we were 3rd owners of the car. It didn't show any previous issues like this and the service records were good. We bought it back in January, and it ran great until about March. We started having electrical issues. We troubleshooted through this group and determined that there is a fuse box under the passenger feet, so when I was riding in the passenger seat, my feet were going on that fuse box, and it was causing issues with the connectors. After two mechanics, we finally got that fixed. But the 2nd mechanic couldn't figure out why it wouldn't shift into 3rd gear. We had first and second, but that was it. Once we took it to a third guy (the best yet), he replaced a solenoid, the wiring harness in the transmission itself, and then found these pieces of spring in the fluid pan. I'm really just trying to wrap my head around whether or not the electrical issues could have caused something in the transmission to get in a bind and break it mechanically.

My 2021 GMC Sierra has a 10-speed (3.0L diesel) with ~40K miles. It will be interesting to see how well this holds up over time with that ~460 lb ft of torque.
