45RFE valve body question

[Mike Barbier]

Hi, I just joined and am not very knowledgeable about transmissions. I did change the solenoid pack today on my 07 ram hemi. A very nice guy on YT posted a video on how to do it. It's shifting correctly now and out of limp mode. YES!! I noticed some strange(?) wear on the side of the valve body. It's on a plate that holds the big springs inside.(told you I don't know crap, lol) the funny wear is around the big hole on the end. Can anyone tell me if its normal or is something getting beat up? I took a pic but you can't see it very well. I did also change both filters and put 9 quarts of synthetic atf+4 back in. Any advice would be appreciated. Thanks
Mike
