WHICH POWER STEERING FLUID TO USE?

[62roadster]

My 1962 Thunderbird service manual says to use Ford “A” power steering fluid, for some reason I always though it should be the “F” trans fluid to use for the power steering. In any event, which is correct and is there a modern day replacement for these fluids?

Back in the day the manuals listed Type A Transmission fluid it is now known as Type F. Type F is what you should be using in your Thunderbirds power steering and convertible top pumps, it was also the correct fluid for the Ford transmissions back in the day. You can use other transmission fluids if your transmission has been rebuilt, but the transmission will not have the very detectable positive shifts that where originally present.

My transmissions have all been rebuilt but I still use Type F in all of them.

Thank you for your advice. I want to clean out my P.S. system and add new fluid, I am considering using a system flush made by Lubegard, wondering if it is ok to use this product, the link is below, they also made a flush and protect combo pack (second link) which is probably the one I would buy,,,thanks

Have no idea about Lubegard, all I have ever done is drain the steering system and refill with Type F steering fluid.
