Hello:

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?

Thanks.

The coupling that connects the pump to the gearbox is the most likely problem. Requires separating the two units. Special tool required to re-assemble. Coupling is less than $20 but tool is about $40. Gearbox uses 85w90 gear oil, pump uses 10w40 synthetic.
