The 2014 Jeep Wrangler uses ATF+4 automatic transmission fluid in its power steering system. Use Mopar ATF+4 or any brand that meets Chrysler MS-9602 specifications.
For the 2014 Wrangler (JK generation), the hydraulic power steering is designed to operate with ATF+4 rather than the older Dexron-style fluids. Using the correct ATF+4 helps ensure smooth steering, proper pump operation, and long-term reliability. Do not substitute Dexron II/III or Dexron VI unless explicitly approved by Chrysler/Mopar for your exact build, and always verify guidance in the owner's manual or on the under-hood label.
Fluid options that meet the spec
Below are common fluids that meet Chrysler MS-9602 and are suitable for the 2014 Wrangler's power steering system.
- Mopar ATF+4 (Chrysler MS-9602) – the factory-approved option.
- Valvoline ATF+4 Multi-Vehicle – a reputable aftermarket option that meets MS-9602.
- Castrol Transmax ATF+4 – designed to meet Chrysler specifications for ATF+4 applications.
Note: When using any third-party ATF+4 product, ensure the bottle clearly states MS-9602 or "ATF+4" compatibility and that it is suitable for Chrysler products.
What to avoid and maintenance tips
To keep the steering system in good condition, avoid mixing incompatible fluids and follow proper maintenance procedures.
- Avoid using Dexron II/III, Dexron VI, or other non-ATF+4 fluids in the power steering reservoir unless explicitly approved for your vehicle by Chrysler/Mopar.
- Never mix different brands of ATF+4; drain and flush if you are switching Fluid brands or if you suspect contamination.
- Regularly check the power steering fluid level with the engine running and the wheels centered to ensure correct readings and watch for leaks.
Using the wrong fluid or letting the system run low can cause noise, stiff steering, and eventual pump wear. For any doubt, consult the owner's manual or a Jeep dealership service advisor.
Additional notes
As a general rule, always refer to the 2014 Wrangler's owner's manual or service bulletin for the exact specification; if you own a modified or non-standard Wrangler, verify the fluid compatibility with the vehicle's power steering system.
Summary: The 2014 Jeep Wrangler's power steering system uses ATF+4 fluid meeting Chrysler MS-9602 (Mopar ATF+4 or equivalents from reputable brands). Do not use Dexron II/III or Dexron VI unless specified; use fluids labeled ATF+4/MS-9602, and consult the manual for exact guidance.

The Correct Fluid Spec: Why MS-11655 Matters
In the old days, power steering was easy: a belt, a pump, and some ATF. Today's Jeeps use electro-hydraulic systems that generate massive heat, requiring specialized stuff like Pentosin CHF 11S.
