* Incompatible Fluids: Transmission fluid and power steering fluid are chemically different and designed for different purposes. Transmission fluid is thicker and lubricates under high pressure and temperature. Power steering fluid is thinner and designed to operate at lower temperatures and pressures.
* Damage to System: Mixing these fluids will cause:
* Sealing Problems: The power steering system seals are designed for the specific properties of power steering fluid. Transmission fluid will cause them to swell, potentially leak, and fail.
* Fluid Pump Damage: The power steering pump relies on the specific properties of power steering fluid for lubrication. Transmission fluid is not compatible and will lead to premature wear and damage.
* Steering Problems: The fluid incompatibility will affect the steering's responsiveness and feel. You might experience sluggish steering, hard turning, or even complete steering failure.
* Potential for Damage to Other Components: The fluid mix could damage other components of the power steering system like the rack and pinion, or hoses.
What to Do:
1. Stop immediately: If you've already put transmission fluid in the power steering, stop driving the car.
2. Flush the system: Take your Altima to a qualified mechanic as soon as possible. They will need to flush the entire power steering system with the proper power steering fluid to remove the incompatible fluid and prevent further damage.
3. Inspect for damage: The mechanic will also inspect the power steering system for any damage caused by the wrong fluid.
Remember: Always use the correct fluids for your car's systems as specified in the owner's manual. If you are unsure, ask a qualified mechanic.
