Im Confused what oil should i use in my front transfer case. the manual say to use the demand drive fluid. But I have heard that the manual is wrong and i should use the LT instead. Also how do i tell if i have ADC? I have a 2006 sportsman 500X2

Lt fluid is the correct fluid for your machine. adc didnt come out untill 07

 

i thought the LT fluid was for ADC

As far as which to use, I'd use what's already in there. When you drain the fluid if it has a dark green tint to it, then thats the regular fluid. LT fluid does not have any colored tint to it.

My 500 has only used the regular fluid. I'll continue to use it until I can't get in any more.

 

The lt fluid superseads the demand drive fluid. It can be used in both adc and non adc. The demand drive fluid is no longer being made and will run out on the shelves. What you cannot do is run demand drive fluid in a adc differential.
