Transmission Lubrication - Models with Dipstick
Transmission Dipstick
For most 2x4 models, a transmission dipstick is located on the right
side of the machine. On the Sportsman, the dipstick is located near the
rear brake disc.
The transmission lubricant level should be checked monthly or 1000
miles (1600 km), whichever comes first. Transmission oil should be
changed annually. With the ATV on a level surface, remove fill plug
dipstick and check the lubricant level. Lubricant should be kept at the
full mark on the dipstick. The correct transmission lubricant to use is
Polaris Premium Synthetic Gearcase Lubricant (PN 2871478).
