Can Use Transmission Fluid for Power Steering? What the Manual Says
Transmission fluid belongs in a power steering system only when the owner's manual names it, so match the fluid to the manual and keep the wrong bottle off the shelf.
On this page
A low reservoir and a noisy pump send many owners to the shelf for a bottle of fluid, and the bottle of automatic transmission fluid is often already there. The question on the label is whether you can use transmission fluid for power steering. Only when the owner’s manual names automatic transmission fluid for the steering system. When the manual names a maker-specific power steering fluid instead, that fluid is the fluid to use, because the wrong fluid may damage the steering system.

Can use transmission fluid for power steering: what the manual decides
Power steering fluid and automatic transmission fluid are both hydraulic fluids, but they are not the same bottle with a different label. The owner’s manual names the fluid for the seals, pump and valves in that steering system. That name on the manual page is the whole answer: match it, and the question is settled.
Honda’s own listing makes the point plainly. Its genuine power steering fluid is manufactured for all Honda vehicle power steering systems, and the listing warns that other manufacturers’ power steering fluid may damage the Honda power steering system. It also points the reader to the owner’s manual for more information. Pouring in transmission fluid without checking the manual works against the maker’s own warning.
That does not make every bottle of transmission fluid wrong for every car. It makes the manual the decider: use the fluid the manual names, whether that is automatic transmission fluid or a power steering fluid.
| What the manual names | Pour | Why |
|---|---|---|
| A maker-specific power steering fluid | The fluid the maker names, such as Honda 08206-9002 | Honda warns other makers’ fluid may damage its system |
| Automatic transmission fluid | The automatic transmission fluid the manual names | The manual is the authority for the system |
| No fluid named on the page | Nothing yet; read the manual | The Honda listing points to the owner’s manual |
Power steering fluid for the job
Once the manual names the fluid, the bottle on the shelf has to match it. The 3 fluids below cover the cases in this guide: genuine Honda fluid, in a single bottle and a pack of 3, and a general Valvoline power steering fluid in a 32 fl oz bottle.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
What to check before pouring
- Read the owner’s manual and use the fluid it names.
- Match the part number on the bottle: 08206-9002 for the single Honda bottle, 08206-9002PE for the pack of 3.
- Read the recommended-applications bullet: the Valvoline bullet names GM 1050017, Chrysler Spec 5931 and Ford Spec M2C195-A.
- Heed the warning on the listing: Honda states other makers’ fluid may damage its system.
- Keep the spare bottle: the Honda pack of 3 leaves fluid on the shelf.
FAQ: garage tools
Can I use transmission fluid in my power steering system?
Only when the owner’s manual names automatic transmission fluid for the steering system. When the manual names a maker-specific power steering fluid, use that fluid instead: the manual is the authority for the system.
What happens if I use the wrong fluid?
Honda’s listing warns that other manufacturers’ fluid may damage the Honda power steering system, and it points the reader to the owner’s manual. When the wrong fluid is already in the reservoir, check the manual for what to do next.
Can I mix power steering fluid and transmission fluid?
Do not mix them. Use the single fluid the manual names, and keep the other bottle off the job. The Honda listing warns that other makers’ fluid may damage its system, and mixing adds a fluid the manual never named.
What fluid does a Honda need?
Honda’s genuine power steering fluid, part number 08206-9002. The listing states it is manufactured for all Honda vehicle power steering systems. It is sold as a single 12 fl oz bottle, and a pack of 3 12 fl oz bottles is listed under part number 08206-9002PE.
Is Valvoline MaxLife a power steering fluid or a transmission fluid?

Its recommended-applications bullet names GM 1050017, Chrysler Spec 5931 and Ford Spec M2C195-A, and describes the fluid as suitable for ABS, disc, and drum braking systems, so read the bullet beside the title and check the manual before pouring.
How much power steering fluid do I need?
The bottles here hold 12 fl oz or 32 fl oz, and the Honda fluid also comes as a pack of 3 12 fl oz bottles. Check the manual for the capacity of the system before buying, and keep the spare bottle for the next top-off.
