The Vauxhall Monaro manual transmission fluid capacity is 4.4 liters across all four listed configurations, covering the 5.7 V8, 5.7 VXR, and 6.0 VXR variants from 2004-2006.
A 4.4-liter capacity is consistent with a transaxle unit, where the transmission and final drive share a common fluid reservoir, resulting in a higher combined fill volume than a standalone gearbox would typically require.
All four configurations share a 12-month check interval under normal use conditions, meaning the fluid level is inspected on an annual basis rather than replaced at a fixed mileage point.
The 5.7 V8 appears across two overlapping model year ranges, 2004-2005 and 2005-2006, both carrying identical 4.4-liter capacity and 12-month check interval specifications.
The 5.7 VXR and 6.0 VXR variants also share the same 4.4-liter transaxle capacity and 12-month check interval as the standard V8 configurations, despite the displacement difference between the two VXR engine options.
All specifications listed apply to normal use conditions, which in fluid service terminology refers to standard on-road driving as opposed to severe or high-stress operating environments.
