@garagelogician, what are the reasons for dropping the pan and replacing the seals/sleeves? Are there known issues with the transmission?

In looking at the TIS guides, it looks like the front has a drain plug, but the rear does not: https://www.newtis.info/tisv2/a/en/e...fferential+oil (see the first two links on the search result).

And yes, the driveshaft was replaced under recall.
