What torque spec did you tighten them down to?
Did you use red Loctite?

 

Maybe that’s the problem? My neighbor does most of my mechanic work and he pretty much just tightened them till tight and snug. I’ only have basic understanding of engines but i know for a fact he didn’t measure how hard he tightened the bolts. So then they need to be tighten down to a certain spec? The bolts was MOPAR parts and came with blue loctite on them

 

Hey there! I’m sorry to hear that you’re having issues with your torque converter bolts to flex plate. I did some research and found a forum thread on Speed-Talk where a user had a similar issue with their torque converter bolts. The thread has some suggestions that might help you diagnose the issue.
One of the users suggested that the torque converter bolts might not be tightened to the proper specifications or in the proper sequence, which could cause them to loosen over time. Another user suggested that the flexplate hub has been known to break or crack at the crankshaft mounting bolts, which can result in a knocking or rattling sound.
I also found an article on GoBigBolt that explains how loose torque converter bolts can cause low acceleration due to slipping gears. It might be worth checking out.
I hope this helps you find a solution to your problem. Let me know if you have any other questions!

 

Is this a bot?
