Does any body in the audience. I’m particular this type of transmission . Replacing this part would only serves gear changes. My problem is same transmission no reverse gear..,
If the band is this far gone, the drum needs replacing anyways. I guarantee you the center of it is wore down and you can see light when you put a straight edge across it. I’ve rebuilt a handful of 4l65e’s and not one had a drum that was reusable
