I have the 4-speed automatic slushbox with lockup. The CVTs back then weren't that reliable so I'm glad I don't have it, and not sporty at all.
If you look on or abouts page 14-118 onwards. I perused the chapter and didn't find any mention of an oil pan but I didn't look that closely. Page 14-118 is the fluid change procedure.
On page 14-187 it shows how to flush the transmission. It just involves unplugging the cooler lines from the radiator.
Maybe the transmission has a cover with a gasket on the end facing away from the engine, I'm not sure.
