PSA for anyone owning a post-1/13/2022 U800, I just found out that CFM quietly changed the crankshaft/crankcase/CVT to be more like the C800s but never updated the manual. Biggest change is that there are now two old dipsticks and their locations have changed. The oil dipstick under the access panel under the right passenger seat is now a transmission oil dipstick and the engine oil dipstick is now located by the rear axle, under the edge of the dump bed.
If you follow the 2022 U800 manual, you'll end up putting engine oil in your transmission dipstick tube. CFM told me that old manuals were accidentally shipped to dealers and they are sending new ones out now.
Learned this the hard way when I put engine oil in what is now the transmission tube. How damaging is that? Is it something I can just flush a couple times or should it go back to the dealer?
