After further inspection, it looks like one of the bolt heads broke off so someone decided to weld where the head was. They also tack welded the other 3 bolts so they don't come loose.
At this point, we are unsure whats causing the knocking sound. Did all that welding throw the balance off and mess stuff up?
If we put the jeep in neutral or gear and feel the transmission oil pan, it vibrates. Once in park, it stops.
To even look at the tranny, we will have to replace the flexplate since they made it damn near impossible to remove. He also thinks it could need a torque converter, rear main seal, and possibly a tranny oil pump.
At this point, dad said he is going to talk to a transmission shop tomorrow and see what they think.
Also, on a side note. The tranny fluid was a whole quart low. Did driving it with low tranny fluid take something out?
