Ok, I know there is alot of information(pages and pages). I cannot find a clear answer to this. I did an oil change the other day. I have not ridden it yet(been working on LED lights). I removed both of the large drain plugs 17mm I think. I replaced the filter and filled it up, started for 15 secs, then filled to the appropriate level. My question is did I also drain the transfer case?? I know that the tranny and engine run on the same oil, and that the transfer case is seperate. Do I need to fill the transfer case now?? The two drain plugs were located: 1 was on the left side toward the front, and the other was on the right side near the rear shock. Thanks for any help.
