Additional Notes

  • The Dodge Charger LX automatic transmission carries a service fill capacity of 5 liters, which represents the amount of fluid needed when servicing the transmission without fully disassembling it, such as during a pan drop and filter replacement.
  • The overhaul capacity of 7.7 liters applies to all configurations covered here, reflecting the total fluid volume required when the transmission is fully disassembled and rebuilt from the ground up.
  • The 2.7-liter difference between the service fill and overhaul capacity indicates a significant volume of fluid remains trapped in the torque converter and other internal passages during a routine service, which never fully drains without a complete teardown.
  • For the Charger 5.7 (2006-2008), the normal-use automatic transmission fluid change interval is set at 120,000 miles or 120 months, whichever comes first.
  • Under severe use conditions, the Charger 5.7 (2006-2008) automatic transmission fluid change interval is halved to 60,000 miles or 60 months, reflecting the accelerated fluid degradation associated with more demanding operating conditions.
  • The Charger 6.1 SRT8 shares the same 5-liter service fill and 7.7-liter overhaul capacity as the 5.7 configuration, despite the larger displacement and higher-performance nature of the SRT8 engine.
  • The 6.1 SRT8 normal-use interval of 120,000 miles or 120 months mirrors the 5.7 specification exactly, while the severe-use interval is likewise 60,000 miles or 60 months for both engine variants.
  • The 6.1 SRT8 appears across two overlapping year ranges in the specifications: 2006-2009 and 2009-2010, with both ranges carrying identical capacity and interval values across both normal and severe use conditions.
