Dodge Challenger (USA / CAN)

Automatic transmission fluid capacity & service interval

Dodge Challenger (USA / CAN) uses automatic transmission fluid with a capacity range of 15,6 to 16 liters. The service interval is 24000 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 318ci engine configuration carries an automatic transmission fluid capacity of 16 liters, which is a notably large fill volume consistent with a full overhaul or dry-fill specification rather than a routine drain-and-refill service quantity.
  • The 360ci engine configuration, introduced in 1973, carries a slightly lower automatic transmission fluid capacity of 15.6 liters compared to the 318ci's 16 liters, representing a measurable difference between the two engine variants despite sharing the same transmission type designation.
  • For the Dodge Challenger 318ci across 1970-1974, a change interval of 24,000 miles is specified under normal use conditions, placing fluid replacement on a relatively extended schedule by the standards of that era.
  • The 360ci configuration lists the same 24,000-mile change interval, but exclusively under severe use conditions rather than normal ones, meaning the interval applies to more demanding operating circumstances such as frequent towing, stop-and-go driving, or extreme temperatures.
  • The 360ci normal-use row carries a capacity figure of 15.6 liters without an accompanying change interval, while the severe-use row for the same engine and years pairs that same 15.6-liter capacity with the 24,000-mile interval, indicating the capacity value itself does not vary by use condition.
