Changing the fluids in Mama's '06 500 X2. She can't find the owner's manual. I changed the oil, front differential fluid, and drained the transmission fluid and upon the advise given by my local dealer put 15 ozs of AGL in the tranny. I can't find a drain or fill plug on the rear diff. So I guess my question is, does the rear diff share the fluid with the trans and if so, did I put enough in it? If there is a drain/fill plug on the rear diff, where is it because I can't find it?

 

Lawdog, this is what I can find for the rear transmission.

The transmission fill plug (1) is located on the left side of the ATV,
under the rear fender, behind the wheel.
1. Position the vehicle on a level surface.
2. Remove the fill plug.
3. Add the recommended oil as needed to bring the level to the
bottom of the fill plug hole threads.
4. Reinstall the fill plug. Torque to 20-25 ft. lbs. (27-34 Nm).

The transmission drain plug (2) is located on the right side of the
gearcase, on the right side of the ATV, behind the wheel well.
1. Remove the fill plug. Remove the drain plug.
2. Drain the oil into a drain pan. Dispose of used oil properly.
3. Clean and reinstall the drain plug. Torque to 20-25 ft. lbs. (27-34
Nm).
4. Add 32 oz. (948 ml) of the recommended transmission oil to bring
the level to the bottom of the fill plug.
5. Reinstall the fill plug. Torque to 20-25 ft. lbs. (27-34 Nm).
6. Check for leaks.

Thank you Sir. PM on the way.

 

The tranny and rearend are one piece and share the same oil.
