My mother-in-law has a Husqvarna mower with a Peerless H2000-006A SilentTrac transmission. It stopped moving so she replaced the drive belt. This did not fix her problem. I cleaned the exterior of the transmission and it will not go into gear. There does not seem to be any exterior mechanical problem with the transmission and everthing on the outside is working correctly.
here is a rubber plug which I suspect is for oil. I would like to replace the oil.
What type of oil is used in this unit?
Is there a replacement kit for servicing the unit?
Is there anything else that can be replaced on the transmission?
Is there anything else that could be the likely cause of the problem?
