When was the lasttime you checked your tranny fluid? You might have fried your tranny.
If your not starting in low gear check the little snow flake button next to the gear shift. If this has been pressed your starting in 3 rd. gear.
Your Yamaha Bruin may not shift out of low gear because something may be wrong with the gear box, so you should have it checked.
Gear will not shift from park, is low fuel the cause?
No it will shift slow.
Try putting gear shift into "neutral" and then shift out of 4x4
D3 means that the vehicle transmission will shift through 3 forward gears (low gear/2nd gear/high gear). D2 indicates only low gear & second gear. Your vehicle will NOT shift into OverDrive unless the transmission is in D3 position.
Assuming you're referring to the transfer case gear shift, it should be in "high" for normal use
could be the modulator valve has went bad !
Park, reverse, neutral, Drive and low
Could be low ATF.
You may have a broken transmission or be low on transmission fluid.
I have the same problem!
