View Full Version : Power Steering Fluid

Yet again I find myself puzzled by power steering fluid questions. The internet is filled with opinions on dexron 3 being a replacement for type A ATF but I can't get a straight answer if it is safe to use it as power steering fluid. My question boils down to what is better for seals to minimize leakage on a power steering system built in 1955. Dexron 3 or modern version Type F ATF

I would stay with trans fluid.

If all your steering components have been rebuilt with new seals then you can use the more modern fluids. If not then I would stick with Type F fluid.

Power steering fluid should not be used with early Ford power steering units as it tends to leak because it has a different composition. Use trans fluid as mentioned previously, Type F should be okay.

Totally agree as one that has gone through this issue with both of our squarebirds.
