68rfe P0868; obvious leak, but not sure where from; what to replace
Well, I'm in the club now. 2017 with 62,000 on it. Bone stock, small amount of towing (probably about 5k-7k miles towing an 8k lb trailer, no towing in the last 40k miles). CEL came on yesterday; threw a P0868. Still driving fine. I did notice when I first shifted into D, it didn't roll immediately like it normally does (should have been my first hint; but I was busy and brushed it off as it's been sitting for a couple weeks). Checked fluid, it was about a quart low. Refilled it just to get it home. Temps never went above 173F, sitting in traffic on a super hot day (about 95 yesterday when I was idling in traffic for almost half an hour). No smells, or anything like that. Checked the pan; it's obviously leaking, but I'm not sure from where. It seems to be all over the pan, and front of the trans but that could just be because it was blown back while driving. No leaks on the driveway, it's obviously just leaking while hot/driving.
Where do you guys think the leak could be coming from?
I suppose this is a good time to replace the pan with something with a drain plug, looking at the PPE; seems like a quality unit. Anything else (other than filters) I should replace while I'm all up in there?
