Power steering fluid?

I just brought home a '79 C30 with hydroboost brakes. The power steering fluid is low, but what kind of fluid do I add? I know some vehicles use "power steering fluid" and some just use ATF...well the fluid I have looks like ATF but smells like PSF! I'm not sure which it is.

I've always used regular ATF, never had a problem.

Yeah, well, it's kinda both...the power steering pump powers the brake booster instead of a vacuum line.

Re: Power steering fluid?

Specs call for power steering fluid, period. This is especially important where hydro-boost is concerned because of the added load on the P/S pump. PS fluid is heavier and lubricates better, also it is less likely to foam or attack seals. jim

Re: Power steering fluid?

On closer inspection last night it does seem more like dirty PS fluid rather than ATF. I'll try and dump the whole thing so I don't end up mixing two different things....
