Additional Notes
- The Holder P 20 transaxle carries a manual transmission fluid capacity of 4 liters, which represents a service fill volume for a transaxle unit combining transmission and axle functions in a single housing.
- Under normal use conditions, the fluid check interval for the P 20 transaxle is set at 150 hours of operation, reflecting a time-based service schedule rather than a distance-based one, consistent with small utility or grounds-care machinery that accumulates runtime in hours.
- The fluid change interval under normal use is specified at 1000 hours, meaning a full drain and refill of the 4-liter transaxle is due after that threshold of operational time has been reached.
- The ratio between the check interval and the change interval is roughly 1 to 6.7, placing six or more inspection points within a single full change cycle across the 1985-1991 production span covered by the P 20 specification.
