Third time was not the charm while trying to stop my rear main leak.
Put everything back together started her up (in neutral) only to hear the most gut wrenching LOUD grinding noise. I can only describe it as if one were to take a spinning flywheel and slowly move it into a solid piece of metal as if using the flywheel as a saw blade. I moved it from neutral into park before shutting it off.
Anyways. I am taking it apart again to investigate. Here is what the TC teeth look like. Any guesses as to what parts are interfering would be appreciated.
Usually only starts in neutral
Had to jack the tranny up past normal mount angle to get oil pan off
**Problem was a bent cover plate for the bell housing. Thank you NEWFIEZJ for convincing me to look past the jacked up torque converter teeth (unrelated damage) to see that the actual points of interference were at the flex plate bolt heads. Damage was surprisingly minimal for how gut wrenching the noise was.
