This ZTR has two transmissions, one for each rear wheel. One of them has a slow leak. The Owner's Manual (page 55) says:
The transmission is maintenance free. There
is no need for level checks or oil changes. If a
leak occurs, replace the unit or contact your
Husqvarna dealer.
"No need for level checks" really means "there is no way to check."
Each of these transmissions has a readily-accessible breather tube. May I add fluid through this tube? If so, what fluid should be used?
