Hudson Wasp

Automatic transmission fluid capacity & service interval

Hudson Wasp automatic transmission fluid capacity ranges from 8 to 10,4 liters. Service intervals include checks at 1000 miles and changes at 25000 miles. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Hudson Wasp automatic transmission carries 10.4 liters of fluid in the 1952-1954 trim, a capacity typical of early hydraulic automatic units that required substantial fluid volume to maintain hydraulic pressure across the torque converter and gear train.
  • The Super Wasp shares the same 10.4-liter automatic transmission capacity as the standard Wasp across the 1952-1954 model years, placing both configurations on an identical service footing for fluid volume.
  • A 1,000-mile check interval applies to all three configurations, reflecting a practice common to early automatic transmissions where fluid condition and level were monitored closely during normal operation.
  • The 25,000-mile change interval is consistent across the 1952-1954 Super Wasp, the 1952-1954 Wasp, and the 1955-1956 Wasp, all under normal use conditions.
  • The 1955-1956 Wasp automatic transmission capacity drops to 8 liters, a reduction of 2.4 liters compared to the 1952-1954 specification, which generally reflects a change in transmission design or unit size between those model year groups.
