On a 2019 Ram 1500 with the 8-speed automatic, a full transmission refill typically requires about 9 quarts of ATF. The exact amount depends on whether you’re doing a simple pan drain and fill or a complete service that includes the filter and, in some cases, the torque converter.
Engine and transmission basics
The 2019 Ram 1500 uses a TorqueFlite 8HP70 eight-speed automatic transmission in most configurations. Transmission fluid capacity can vary by engine choice and service method, so it’s best to reference the factory spec or service manual for your exact build.
Common service scenarios
Below are typical fluid quantities you’ll encounter during maintenance, depending on the service you perform.
- Drain and fill (pan drain only): about 6–7 quarts replaced.
- Full transmission service (pan drop, filter replacement, and refill): about 9–10 quarts replaced.
- Total system capacity (including torque converter and cooler routing, for a complete refill): roughly 9–10 quarts.
In practice, the exact amounts can vary by model year, engine, and whether a new filter and gasket are installed. Always confirm with the vehicle’s service manual or a dealership service department.
How to approach a fluid change safely
When performing a transmission fluid service, adhere to the recommended fluid specification and steps. The 8HP70 typically requires Mopar ATF+4 (or a fluid with equivalent spec) that meets Chrysler MS-9602. Use the proper tools and follow a careful procedure to ensure a full and even fill.
- Confirm the correct fluid type and specification for your vehicle (ATF+4 or equivalent as per Mopar/Chrysler specs).
- Warm up the transmission by driving for a few miles; operate through gears if necessary to circulate fluid.
- If performing a pan drop, drain the old fluid completely and replace the pan gasket and filter if accessible.
- Refill gradually to the recommended total capacity, checking the level per the service procedure; many modern 8-speed units do not have an easily accessible dipstick and require a scan tool or a specified procedure.
- Recheck the level after a short drive and re-zero with the engine warm and the vehicle level.
Note: The Ram 1500's transmission may not have a traditional dipstick; level is often checked via a dealer diagnostic tool or a specific procedure in the service manual. Consult the owner’s manual or dealer for the exact procedure on your truck.
Summary
In short, plan to use about 9 quarts of ATF for a full fill on a 2019 Ram 1500 with the 8-speed automatic. Expect approximately 6–7 quarts if you’re only draining and refilling the pan, and around 9–10 quarts for a complete service that includes the filter and potential torque converter drain. Always use the recommended ATF+4 fluid and follow the official service procedure for your engine/transmission configuration.
Notes and practical guidance
This article reflects typical capacities for the 8HP70-equipped Ram 1500. Exact figures can vary by VIN, engine choice (e.g., V6 vs V8), and whether you replace the filter or gasket. For the most accurate specification, consult the vehicle’s owner manual or a Chrysler dealer service bulletin.
