The pan did not look like it was concaved in causing the rubbing. But was had to see for sure. I wonder if you could get away with a thicker gasket to give you enough clearance. Unless some one tells you if there IS to much play in the sprocket, and can eliminate the play.
did you pull the drive sprocket and inspect it? very common for the snap ring to be forced out from converter pressure for the same reason also common to wear the crankshaft thrust bearing going in the other direction. easy to check crank end play many times i've seen it as much as about 1/4"
Wonder if somebody did not seat the torque converter properly and tightened it down, ran it before they figured it out, I am catching up so I assume the answer is coming up, lol.
Thank you for posting. I needed to see exactly where that vacuum modulator was!
Glad my videos are helping someone. Thanks for letting me know.

I was able to straighten the pan a little. A gasket was not used by the previous repair shop. So between the two I think there will be clearance.
did you find out why the drive sprocket was rubbing? if not you need to pull it back out and fix or replace the drive sprocket
The drive sprocket was rubbing because the cover was slightly dented in, and the PO didn't use a gasket.

@@deakin2880 yes removed both the drive, driven and chain. Checked chain wear per Manny. All is good.
real good chance that happened and was fixed before you got the coach.

No definitive answer. Thinking maybe the damage was done prior to the last rebuild.
