The Chrysler Pacifica, with its 9-speed automatic transmission (the 948TE), uses Mopar ATF+4 transmission fluid. This specification applies to most 2017–present Pacifica models, including the hybrid variant. Dexron VI or other generic automatic fluids are not approved for this transmission, and using the wrong fluid can affect shifting and warranty. Always verify with the owner's manual or a dealer for your exact VIN.
In this article, we explain the official fluid requirement, how it applies across model years, and practical steps for sourcing and service to help you keep the Pacifica’s transmission performing reliably.
Fluid specification and model applicability
The 948TE 9-speed automatic used in most Pacifica models is designed to operate with Mopar ATF+4. Chrysler's official service data specifies ATF+4 as the correct fluid and warns against using Dexron VI or other universal ATFs. This guidance generally covers both the gasoline Pacifica and the Pacifica Hybrid, but always check your VIN-specific manual for any market-specific deviations.
To keep your engine and transmission performing well, adhere to the factory specification for maintenance intervals and service procedures.
Where to source and what to avoid
- Mopar ATF+4 is the official fluid recommended by Chrysler for the 948TE 9-speed automatic in the Pacifica.
- Avoid Dexron VI, Mercon, or other universal ATFs unless a dealer explicitly approves them for your VIN and market.
- When buying, prefer OEM Mopar ATF+4 or reputable brands that certify compatibility with ATF+4; check product labeling to confirm ATF+4 compatibility.
Concluding: Ensuring you use the correct ATF+4 fluid helps prevent shifting issues and preserves warranty coverage. Always verify with your manual or dealer if you’re unsure about your specific vehicle.
Service considerations and guidelines
Maintenance work on the Pacifica’s 9-speed automatic should follow manufacturer procedures. Because some models are sealed and rely on precise fluid levels, many owners opt for professional service to perform drain-and-fill or transmission flushes as recommended by Chrysler for their year and market.
- Confirm the transmission type (948TE) and the required fluid (ATF+4) from the owner's manual or dealer.
- Source Mopar ATF+4 from an authorized dealer or a reputable parts store; verify the product label.
- Choose the appropriate service approach (drain-and-fill or professional flush) per the manual and your vehicle's condition.
- Ensure the system is filled to the correct level and that the vehicle is operated at the proper temperature as per spec during fill.
- Document the service and monitor for any shifting or transmission behavior anomalies.
Concluding: Using the correct ATF+4 and following the proper service procedure is essential for the 9-speed automatic's longevity. If you’re unsure, seek professional service from a Chrysler-certified technician.
Summary
In short, the Chrysler Pacifica's transmission uses Mopar ATF+4 as the official fluid for its 9-speed automatic (948TE). Do not substitute Dexron VI or other universal ATFs. Confirm the fluid requirement with your owner's manual or dealer, and rely on professional service if you’re not experienced with sealed transmissions. This ensures smooth shifting and prevents transmission wear over time.
