Let’s Play “Is it motor oil or ATF?”

The above can be done in steps if required ie, shut the engine down before the pan has been pumped dry and resume the process when refilled. That's how I did my trans. PAS is altogether a different matter! A shame GM in the manual didn't offer up some guidance on how to replenish the PAS reservoir as fast as the pump is shifting it.

Sounds like you need someone to put fluid in the PAS reservoir as you're letting it come out.... Kinda hard to do when working by yourself though!

Definitely easier with someone in truck, but a worthwhile and simple process.

I'm not sure it's even possible. The PAS pump throws it out faster than anyone could keep up with!

You can fill the reservoir, start and immediately shut off the engine, fill the reservoir, rinse and repeat until the level holds. Then turn the steering wheel back and forth, check level, rinse and repeat. If you get air in it, it may whine forever after.
