420A Awful grinding from transmission

[DrewmHolland]

After some hard driving last night my transmission started making an awful racket so I took the starter off and found that every
flywheel bolt came loose but after tightening them up the noise hasn’t stopped, it shifts great through every gear and makes the same noise with and without the clutch in. Please help me

That's one of those noises that is hard to pinpoint from a video.

How loose were the flywheel bolts? Like walking out or just not very tight? If they were loose enough to allow play in the assembly, it has probably destroyed the throwout bearing and possibly some damage to the pressure plate. Unfortunately the only way to check for this is removal of the transmission.

Yeah I’m gonna assume my throw out bearing is cooked and now the whole transmission shakes violently so I’m gonna have to drop it out

I would go ahead and check the flex plate as well. It is quite thin and would probably warp easily in the scenario of a loose flywheel.

Well it looks like my bell housing isn’t doing great

Turns out the bolts holding the flex plate to the crank came loose as well and were literally walking their way out which caused this whole mess

Well that's not fun. There is a reason they have a certain torque spec.

They were torqued
