How much transmission fluid does a ProMaster take?
Most Ram ProMaster vans with the common 6‑speed automatic transmission take about 11 quarts of automatic transmission fluid (ATF) to fill from empty, including the torque converter. If you drain only the pan, you’ll typically remove around 9 quarts, though exact amounts depend on the specific transmission variant and model year. Always verify the exact capacity for your vehicle in the owner’s or service manual.
Transmission fluid capacity for common ProMaster configurations
The following figures reflect typical capacities you may encounter when refilling an automatic transmission in a ProMaster. Variations can occur based on year, trim, and whether a filter is replaced during service.
- Total system capacity (full fill, including torque converter): about 11–12 quarts (10.5–11.5 liters).
- Pan capacity (fluid remaining in the pan after a drain, without a new filter): typically 9–10 quarts (8.5–9.5 liters).
- Fluid specification: use the fluid type specified in your manual (commonly Mopar ATF+4 or Dexron VI, depending on model year and transmission). Do not mix fluids; follow the exact spec for your vehicle.
Note: These figures are approximate and can vary with model year, transmission variant, and whether a filter replacement is performed. Always confirm with the official documentation or a qualified technician for your exact van.
How to check and refill accurately
When performing a transmission fluid change or refill, follow these steps to ensure the level and fluid type are correct:
- Warm the van to operating temperature to ensure an accurate reading.
- With the engine running and the van on level ground, shift through all gears (P, R, N, D) and return to Park, as applicable for your model.
- Check the transmission dipstick (if equipped) and add fluid in small increments until the correct level is indicated on the dipstick.
- Use the recommended ATF specification stated in the manual (often Mopar ATF+4 or Dexron VI, depending on year); never mix fluids.
- If you are replacing a filter, drain the pan completely, replace the filter, then refill to the proper level and recheck after a short drive.
Incorrect fluid type or over/underfilling can cause shifting problems and potential damage. When in doubt, consult a dealer or a certified mechanic.
Summary
For most Ram ProMaster vans, you should plan on roughly 11–12 quarts of ATF for a full refill, with about 9–10 quarts in the pan after a drain. Exact capacity depends on the transmission variant and model year, so always consult the owner’s or service manual to confirm the correct amount and fluid specification for your vehicle.
