My '04 400 sportsman's transmission is skipping under heavy load, much worse in low or reverse, sounds like one of the chains inside are skipping over the sprokets. Has anyone here every replaced these chains. If so what are some other parts that will likely need to be changed out as well. Is it most likely that both chains should be changed while i'm in there? Does the trans have to come out or can it be done in place? Thanks for any help

Hi,

The trans needs to come out of the bike. Thats the worst part of the entire job. Do both chains and while your in there, bearings are a good idea too. Not difficult at all, just get a good manual.

I have the service manual and it says to remove the rear rack, and fenders, air filter box is any of this needed, it looks like it should come out from the right side without any of that removed.
