Frequently Asked Questions
Can sealed transmissions be serviced?
Sealed transmissions can be drained and refilled through vent holes requiring unit removal, though manufacturer discourages servicing. Fresh 20W-50 oil sometimes extends life temporarily but often just delays inevitable replacement.
Why won't my Countax move forward or backward?
Non-movement indicates disengaged bypass levers left in freewheel position, broken drive belts, low transmission fluid, or failed hydrostatic units. Check bypass lever position first; verify belt condition second before diagnosing transmission failure.
What causes transmission to work when cold but fail when hot?
Hot-failure symptoms indicate worn internal components allowing fluid bypass when heated, low fluid levels reducing hydraulic pressure, or damaged pump surfaces losing compression. Typically requires transmission replacement rather than repair.
How do I purge air from hydrostatic transmission?
Purge air by engaging bypass levers, raising rear wheels, running engine whilst moving control levers forward and backward five times, then disengaging bypass and repeating. Air causes spongy response and power loss.
How often should transmission fluid be changed?
Change hydrostatic transmission fluid every 200-400 hours or annually on serviceable units, using proper 20W-50 oil maintaining optimal viscosity. Many consumer units feature sealed transmissions marketed as maintenance-free lasting 300-600 hours before replacement.
